Description
Applications
Recommended use: driving devices that need a small, light and powerful motor.
Inverter and cooling
If the motor runs briefly with long breaks, pouring about 1 l of Reniso KM32 oil (used in refrigeration) into the motor is enough. For the motor to run long at high power, connect it in delta to an inverter with twice the motor's power, about 150kW, and fit very good cooling.
Oil cooling
Connect a car radiator or heater core, an expansion tank and an oil pump to the motor. Fill the cooling system with enough oil for it to circulate evenly. The motor temperature should not exceed 90°C.
Power and current
With very good cooling, the motor can draw 140A continuously, reaching 35kW, and 20A for 280 seconds, reaching 70kW.
Do not connect the motor directly to 400V three-phase power; connect it through an inverter. The leads connecting the inverter to the motor should be as short as possible. Cover the screws holding the electrical leads with an insulating cover.
