Atlas Vertical Wind Turbine Generator (15 kW motor, easy 1 kW)

Meet ATLAS — the world's best-selling vertical wind turbine, capable of generating power even by hand. Trusted at Arctic research centres, on California homes, and aboard Maersk and MSC fleet ships — wherever the wind is gusty, turbulent, or shifts direction.

This purchase includes the generator with built-in IoT charge controller. Blade set sold separately — three options for your site's wind profile.

Power & Performance

• Easy output: 1 kW in good wind
• Starts at: 2 m/s (low-wind blades) — one-third the cut-in of horizontal turbines
• Three swappable blade sets for any site: Low-Wind (2–20 m/s), Standard (4–25 m/s), High-Wind (5–35 m/s)
• Daily energy yield: 0.5–8 kWh per day depending on site
• Annual yield: 180–2,500 kWh depending on average wind
• Noise: 35–40 dB — quieter than a conversation
• Built-in IoT charge controller — monitor power, wind, and solar data from your mobile app

Why vertical-axis wins for real sites

Horizontal turbines need clean, steady wind from one direction. Atlas thrives on the real-world wind found at homes and urban sites — gusty, turbulent, constantly shifting. Atlas captures wind from any direction without yawing, generates in turbulent flow where horizontals stall, and self-starts in light, shifting gusts.

Inside the Atlas — Industrial-Grade Engineering

Atlas uses the same premium 15 kW continuous-rated motor as the Magnum. At Atlas's typical 1 kW output the motor runs at less than 7% load — cold-running, near-zero copper losses, service life exceeding 30 years.

• 24-pole permanent magnet generator with NdFeB N42 super magnets (60×25×5 mm, nickel-coated, bread-shape)
• Skewed magnet mounting — minimizes cogging torque, enables self-start in light winds
• 4 kg of pure copper winding, 90 turns per stator slot
• Class 200°C high-temperature enameled wire (IEC 60317-13 GR 2) — the same insulation grade used in industrial servomotors and EV drivetrains, certified CE / UL
• ±0.05 mm precision tolerances across all machined components
• Generator dimensions: stator 16 cm × 12 cm (2.4 L volume); 24 magnets at 60×25×5 mm = 180 cm³ total
• Vertical rotor: 1030 mm diameter × 1005 mm blade height = 1.035 m² swept area
• Three swappable blade sets — choose by site wind profile (low-wind set capped at 20 m/s for safety)

Why 15 kW continuous and 22 kW peak?

The motor's 15 kW continuous rating is what it can sustain indefinitely without overheating — set by the Class 200°C wire insulation, 4 kg copper mass for heat absorption, and passive cooling of the housing. The 22 kW peak rating is the short-term overload capacity for gusts, limited by the N42 magnet demagnetization threshold and stator iron saturation. For Atlas, which typically outputs 1 kW, this means the motor runs at less than 7% load — almost no copper losses (which fall with the square of current), no measurable temperature rise, and a service life that can exceed 30 years.

How power is calculated

Wind power available follows the formula P = ½ × ρ × A × V³ × Cp × η, where wind speed (V) is cubed — small increases in wind speed produce dramatic increases in output. Atlas's power coefficient (Cp) reaches 0.28 in good wind thanks to skewed magnets and curved aerodynamic blades. Combined with 92% electrical efficiency, Atlas extracts ~26% of available wind energy — strong for a vertical design that prioritizes consistency over peak.
