Variable frequency adjustable speed three-phase asynchronous motor is completely enclosed, squirrel cage type structure. It has the advantages of novel design, compact structure, beautiful shape, high efficiency and torque, good starting torque performance, energy saving, low noise, small vibration, safe and reliable operation, etc.
This series of base ranges from 63 to 355, and the power rating and mounting size fully comply with the IEC standards.
The cooling mode is IC416, and axial fan with independent power supply is forced to cool. When the cooling mode is IC411, external fan rotating with the motor to cool.
