Product technical characteristics




Electrical performance data of products




Mechanical dimension data of products

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

Cooling: IC416

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.

Product advantage


Product application area

Motors can be used for non-pole speed machines for good efficiency and control, such as ventilation, pump, hydraulic system, paper machinery, rubber machinery, etc.
