Variable frequency motors that are designed specially and equipped with frequency converter can work under variable-frequency power.
Variable frequency motors drives with constant torque variable speed by under base frequency, and with constant power variable speed by over base frequency.
Motors are equipped with ventilation for good cooling under different speed.
Power range: 0.55~1800KW
Frame range: H80~H630
Frame material: gray cast iron or steel plate welding
Standard mounting: IEC60034-F
Standard protection: IEC60034-5
Specific winding can support various voltages (50HZ or 60HZ)
Motors can be equipped with encoder that can fluently start and exactly controlled.
It’s suggested that big power motors be mounted with insulated bearings.
Heater can be added to prevent moisture.
PTC, PT100 and other thermal elements can be chose to protect winding and bearings.
