One motor, inside every Atlas and Magnum, now sold on its own

The motor that turns inside every TESUP Atlas and Magnum is now sold on its own, as the TESUP Industrial Permanent Magnet Motor / Generator.

It is a 3-phase permanent magnet machine rated at 15 kW continuous and 22 kW peak. In our turbines it works as a generator, turning wind into electricity. With a driver, it runs as a motor.

Tested before it ships

Every TESUP generator is tested before it ships. On the bench, each one is wired to a TESUP charge controller through its three phase wires, and it carries a label with its own serial number and QR code.

Inside the Atlas and the Magnum

The Atlas, our vertical turbine, reaches about 4.5 kW at 500 RPM in a 35 m/s wind. The Magnum, our horizontal turbine, reaches about 12 kW at 1,200 RPM in a 22 m/s wind. Both stay inside the motor's 15 kW continuous rating, so it rarely has to work hard.

How it is built

• Stator: 12 poles, 36 slots, 3-phase distributed winding, laid out for low cogging and a smooth sine-wave output.
• Magnets: 24 N42 neodymium magnets, mounted skewed to cut cogging torque by about 80%.
• Copper: 4 kg in total, Class 200 °C enamelled wire, wound in two parallel strands to share the current and the heat.
• Core: 240 laminated silicon-steel sheets, 0.5 mm each, to keep eddy-current losses low.
• In numbers: about 95% efficient at rated load, up to 2,000 RPM, turns in both directions, 20 kg.

It cuts in at about 50 RPM and gives around 1 kW at 200 RPM, a typical Atlas speed in light wind.

Sold on its own

Outside our turbines, the same motor suits electric vehicles and conversion kits, industrial machinery, marine propulsion, robotics, off-grid hybrid systems and micro-hydro.

One thing to know: as a motor it needs a compatible driver or controller for speed and current control. Running it without one can cause overheating and damage.
