Wound stators in their housings, before assembly. Copper, laminated steel, three phases.

What “15 kW continuous, 22 kW peak” actually means

Two ratings, two entirely different limits. The 15 kW continuous figure is what the machine will sustain indefinitely without cooking itself, and it is set by heat: Class 200 °C enamelled wire to IEC 60317-13 GR 2, four kilograms of copper acting as a thermal reservoir, parallel-strand bundling that doubles current capacity and spreads the heat across thin conductors, and a housing that cools passively. The 22 kW peak is short-term overload for transients, and it is bounded by physics of a different sort — the demagnetisation threshold of the N42 magnets and saturation of the stator iron.

Here is the part that matters more than either number. A generator rating describes what the machine can absorb without damage. It says nothing about what it will produce. That depends entirely on what you connect to the shaft. Maximum speed is 2,000 rpm, efficiency is about 95% at rated load, and it runs bidirectionally — but a modest rotor turning slowly will draw a small fraction of 15 kW out of it, and no amount of generator headroom changes that.

A rating is a ceiling, not a promise. What turns the shaft decides the number you actually get.

We would rather say that plainly than sell one to somebody expecting fifteen kilowatts from a small rotor in light air. The headroom is still worth paying for — a generator run permanently at its limit is the most reliable way to kill a machine early, and this one at a typical few kilowatts is loafing — but headroom and output are not the same thing.

What is inside it

A 12-pole stator with 36 slots, three-phase distributed winding in a fractional-slot configuration for minimal cogging and a clean sinusoidal output. Ninety wires per slot — two parallel strands of forty-five turns, 0.70 mm enamelled copper, the insulation grade used in industrial servomotors and EV traction motors. Four kilograms of copper in total.

The rotor carries 24 NdFeB N42 magnets, bread-shaped, 60 × 25 × 5 mm and nickel-coated — 180 cm³ of magnet in total. They are mounted skewed, which cuts cogging torque by around 80%: smoother torque, easier starting, longer bearing life. The core is not a casting but a stack of 240 individual 0.5 mm silicon-steel laminations built up to 12 cm, about 16 cm in outside diameter, which is what keeps eddy-current losses down. Machining is held to ±0.05 mm, and the unit is EMC compliant to EN 61000-6-3. All in, it weighs 20 kg.

None of that photographs well and none of it appears on a box. It is, however, the entire difference between a generator that is still turning in ten years and one that is not.

Olympia — state capital, county seat of Thurston County, at the head of South Puget Sound.

Where they are going

Olympia is the capital of Washington and the county seat of Thurston County, a city of 55,605 people at the 2020 census anchoring the South Puget Sound region, about fifty miles south-west of Seattle. Its downtown is partly built on filled tideland from the dredging that created the deep-water port, and its climate is warm-summer Mediterranean — dry Julys, and the rain arriving between November and January.

We do not know what these motors are for, and we are not going to invent a story about it. This model goes into electric vehicles, industrial machinery, marine installations, robotics and off-grid power systems, and a port city is a plausible home for most of those. One thing is worth saying regardless: if the intended use is wind, the head of Puget Sound is a sheltered inland waterway, and it is a considerably weaker wind resource than the Washington coast or the Columbia Gorge. That is not a reason against the motor. It is a reason to measure before sizing anything around it.

What it costs, and what it does not include

The motor is $659 on this store as this is published, on the product page, itemised, with nothing held back for the checkout. That buys the machine on its own: generator, housing, shaft. It does not buy a rotor or blades, a mount or a tower, a rectifier, charge controller, inverter or batteries, the wiring between any of them, or the electrical work and permissions that apply where you are. A component sale is honest about being a component.

If you are building something wind-driven around it, one more purchase comes first: an anemometer at $219. Power in the wind goes with the cube of speed, so a site that is 20% slower than you assumed gives roughly half the energy. A season of real measurements at your own address is worth more than any figure we could publish about ours.

Our thanks to the customer in Olympia for the order. Every specification above comes from our own published data for this model and is checkable on the product page; the price is the one on this store on the day of publication. If you are designing around a generator, hold us to all of it.

Crates on the line in our own factory, each packed to the same list.

Where it is going, for anyone picturing the Aegean

Ilioupoli takes its name from Heliopolis — the sun city. It was settled from 1924 by Greek refugees from Asia Minor, and it is now a dense suburb of about 12.7 km², its built-up area continuous with the suburbs around it, with the forested ridge of Hymettus covering its eastern half. That is a very different place from the postcard. It is not a headland, it is not an island, and it is not the open Aegean.

This matters because the wind that reaches a roof in a continuous built-up area has already been through several kilometres of buildings. It arrives slower, more turbulent, and constantly changing direction — and with a forested mountain immediately to the east, the direction it arrives from depends on the day. The etesians, the meltemia, are real: strong dry north winds that blow across the Aegean from roughly mid-May to mid-September. But they are a sea wind, and a suburban rooftop under a ridge sees a considerably rougher, more broken version of whatever is happening offshore.

A suburb is a harder wind site than a cliff. That is not a reason to skip the turbine — it is a reason to pick the right kind.

One thing that does not matter much here: altitude. Ilioupoli climbs the foot of Hymettus, but at a couple of hundred metres the air is only about 2% thinner than at sea level, and power scales directly with air density. It is a rounding error. We mention it only because we made a great deal of the same correction when we wrote about a customer at 1,600 m in South Africa, where it costs about 15%. Here it does not, and it would be dishonest to imply otherwise.

Why a vertical machine for a site like this

A horizontal turbine has to point into the wind to work. In clean, steady air that is an advantage — it is why every large wind farm is horizontal. On a suburban roof, where the wind changes direction every few seconds, the machine spends a meaningful part of its life turning to face air that has already moved on.

A vertical machine has no direction to find. It takes wind from any bearing, which is exactly the property you want where the flow is broken and shifting. It starts turning at 2 m/s with the low-wind blade set — about a third of the cut-in of a typical horizontal machine — which matters on a site whose average is modest and whose good hours are scattered. And it runs at 35–40 dB, quieter than the conversation you are having beneath it. In a neighbourhood where the houses are continuous with each other, noise is not a specification, it is a relationship with the people next door.

Athens at dusk. Ilioupoli sits six kilometres south-east of the centre, under Hymettus.

There are three blade sets, each laser-cut from 1.2 mm high-strength aluminium and matched to a wind profile rather than to a marketing tier. Low-wind blades run from 2 to 20 m/s for a 2 kW peak. Moderate-wind blades run from 4 to 25 m/s for 3.8 kW. High-wind blades run from 5 to 35 m/s for 4.5 kW, in a six-blade configuration built for exposed coastal sites. Choosing the wrong one is the most common way to be disappointed by a small turbine, and for a sheltered suburban roof the answer is usually the low-wind set — the one with the smallest headline number.

What is actually in the crate

The machine going to Athens is an Atlas, and its body is one sealed aluminium housing containing the generator, the built-in IoT charge controller, the display and every connector. There is no second box to find a wall for and no separate enclosure to weatherproof. Weighed on our own workshop scale it read 22.30 kg — a Teknika TCS-K2+R, 300 kg capacity, 50 gram divisions, which is a workshop instrument and not a certified trade one. That is the body alone, without blades or mast, and it is the number your roof structure has to start from.

Mounting flange, cabling, fixings, tools and the manual, packed around the body.

Inside the housing is the same 15 kW continuous-rated motor we put in the Magnum, which at a typical 1 kW output is running at under 7% of its rating — cold, unstressed, and a long way from the limit. The stator is a 12-pole, 36-slot three-phase distributed winding in Class 200 °C enamelled copper to IEC 60317-13, the insulation grade used in industrial servomotors and EV drivetrains. None of that photographs well. All of it is why the machine is still there in ten years.

What it costs on this store, and what it does not cover

It is $1,399 on this store as this is published, and that price includes the built-in IoT charge controller — there is no separate controller to buy, which is the main reason this bill is shorter than the Magnum one. The blade set is chosen to match your site rather than picked off a shelf, so please talk to us before you order rather than guessing from this page: the right set for a sheltered suburban roof is not the one with the largest number on it.

What the price does not buy: a mast or roof mount, the foundation or fixings into your structure, the cable run down to wherever the power is going, batteries and an inverter if you are storing it, and any electrical work, connection agreement or planning permission that applies where you live. None of that is hidden — it is simply site-specific, and anyone quoting you a single all-in figure for a Greek rooftop has not seen your roof.

Before any of it: measure your wind

Every figure above is worthless without one we cannot supply: the wind at your address. Our own published range is 180 to 3,500 kWh a year, and that span is not vagueness — it is the honest width of the answer once you account for site and blade set. Power goes with the cube of wind speed, so two roofs on the same street can differ by a factor of two in speed and eight in energy. In a dense suburb under a ridge, that variation is the rule rather than the exception.

So measure first. An anemometer costs a fraction of a turbine and settles the question inside a season. Then put your own measurements into the calculator on the product page — your wind, your tariff, your roof. For some of you it will say the numbers work comfortably. For others it will say a turbine is the wrong purchase at your address, and we would far rather it told you that before you bought one than after.

Our thanks to the customer in Ilioupoli for the order. Prices are those on this store on the day of publication and are checkable on the product page at any time. The weight came off our own scale and the wind facts are the ones we would want if we were the ones buying. Measure your site — then hold us to every figure above.

Tonight, the summer sky is preparing for one of its most beautiful sights: the Strawberry Moon. This full moon, traditionally connected with June, is known as the first full moon of summer and will brighten the night sky as the month comes to an end.

Despite its sweet name, the Strawberry Moon does not usually appear bright pink or red. Its name comes from seasonal traditions linked to the time of year when wild strawberries were ready to be gathered. However, when the Moon rises low on the horizon, it may appear warm, golden, or amber because of the way light passes through the atmosphere.

For many people, tonight’s moon will be more than just a beautiful view. It is also a reminder of how closely life on Earth is connected to natural cycles. The movement of the Moon, the changing of the seasons, the direction of the wind, and the conditions of the sky all shape the world around us.

This is where nature becomes more than something to observe. It becomes something we can work with.

As the Strawberry Moon illuminates the night sky, Wekraft wind turbines can help illuminate your home by turning the natural power of the wind into clean, usable electricity.

Our smart Brazilian distributor, Company Import Brasil, recently introduced a simple yet effective improvement for the Atlas Wind Turbine low wind speed blades. With a practical idea, they created an additional surrounding support around the blades, helping them connect more firmly with each other during rotation.

This simple intervention made a noticeable difference. By strengthening the connection between the blades, vibration was reduced, and the blades began to rotate more smoothly and efficiently. As a result, the Atlas wind turbine gained a more stable spinning performance, especially in low wind conditions.

The beauty of this improvement lies in its simplicity. A small structural support around the blade set helped create better balance, stronger movement, and smoother rotation. It is a great example of how practical field experience can lead to smart product improvements.

Wekraft proudly works with creative and solution-oriented partners around the world. The idea from Company Import Brasil shows how our global distributor network contributes not only to sales and delivery, but also to continuous product development and real-world innovation.
