TESUP Industrial Permanent Magnet Motor / Generator (15 kW continuous, 22 kW peak)

TESUP Industrial Permanent Magnet Generator — 15 kW continuous, 22 kW peak. The same premium motor powering our award-winning Magnum horizontal and Atlas vertical wind turbines — now available standalone for electric vehicles, industrial machinery, marine, robotics, and off-grid power systems.

Power & Performance

• Continuous rating: 15 kW (sustained indefinitely)
• Peak rating: 22 kW (short-term overload)
• Type: 12-pole stator (24-magnet rotor), 3-phase permanent magnet generator
• Max RPM: 2,000
• Direction: Bidirectional (CW + CCW)
• Efficiency: ~95% at rated load
• Weight: 20 kg

Industrial-Grade Engineering

• 12-pole, 36-slot, 3-phase distributed stator winding — fractional-slot configuration for minimal cogging torque and sinusoidal voltage output
• 90 wires per stator slot — 2 parallel strands × 45 turns of 0.70 mm Class 200°C enameled copper (IEC 60317-13 GR 2), the insulation grade used in industrial servomotors and EV traction motors, CE / UL certified
• Parallel-strand bundling doubles current capacity and distributes heat — motor runs cold even at sustained full load
• 4 kg of pure copper total winding mass — exceptional thermal reservoir
• 24-magnet rotor with NdFeB N42 super magnets (60×25×5 mm bread-shape, nickel-coated), 180 cm³ total magnet volume
• Skewed magnet mounting — minimizes cogging torque by ~80%, smoother torque curve, longer bearing life
• Silicon-steel laminated stator core — 240 individual 0.5 mm electrical-steel sheets stacked to 12 cm total height, ~16 cm outer diameter. Transformer/motor-grade construction that minimises eddy current losses
• ±0.05 mm precision tolerances across all machined components
• EMC compliance: EN 61000-6-3 (emissions and immunity)

Why 15 kW continuous and 22 kW peak?

The 15 kW continuous rating is what the motor sustains indefinitely without overheating — set by Class 200°C wire insulation, 4 kg copper for heat absorption, parallel-strand bundling that doubles current capacity, and passive housing cooling. The 22 kW peak rating is short-term overload for transients, limited by N42 magnet demagnetization threshold and stator iron saturation. Running at partial load means almost no copper losses (square of current), no measurable temperature rise, and service life exceeding 30 years.

Motor Output vs RPM

Applications

• Vertical & horizontal wind turbines (Magnum / Atlas bodies)
• Electric vehicles (cars, e-bikes, scooters, conversion kits)
• Industrial machinery and automation
• Marine propulsion and onboard generation
• Robotics and servo systems
• Off-grid hybrid power systems
• Hydroelectric micro-generation

⚠️ Driver/controller required. This motor requires a compatible driver/controller for proper speed and current control. Operating without one may cause excessive current draw, overheating, and damage. Due to its permanent magnet rotor, the motor can stop instantly when commanded by the driver — ideal for EV, industrial machinery, and automation applications.
