Industry Standard and High Efficiency A.C. Motors

One of the most popular and widely used products – Three-Phase Induction Motors IEC and NEMA.

Frame sizes from 63 to 200 IEC with IP 54 protection, single and multi-speed.
NEMA frame sizes from 140T to 326T.
Motors are constructed in light weight aluminium frame up to size 132, providing excellent heat transfer, the larger motors are produced in cast iron, providing excellent cooling and strength for heavy duty industrial use.

Motor only selection: IEC and NEMA 3-phase induction motors – 63 to 200 frame and flame-proof motors.

Our motors are designed for industrial applications and have been chosen for their flexibility and high performance with a full range of gearboxes and controls. This standard type of product is used in industry for air conditioning, elevators, escalators, agriculture and mining. Special configurations are available with performances ranging from 1 kW to 300 kW and mounting variations, foot, flange and foot/flange.

To order this type of motor, you may want to check the following to help us specify the correct product for you:
indoor/outdoor use, voltage, frequency, output, RPM, ambient temperature, direct or belt drive, type of enclosure, load inertia, application details and environment, size envelope, type of electrical supply.
