Selection of motors for different Engg. application

1. For Cement industry:

Various types of motors for pumps, fans, conveyors ,crushers, kilns an mills
Major mill motor may be synchronous motor.
Motors should be dust protected, highly reliable automatically controlled.

2. Chemical, Rubber, Petrochemical Industry

Require all types of motors, all size of motors
Requires non sparking, flame proof, increased safety
Variable frequency synchronous motors supplied by static frequency converters.
Direct coupled induction motors requires for compressor drive

3. Material handling applications.

Squirrel cage motors with high starting torque are used for conveyor applications.

4. Machine tools application

Generally fixed speed motors with gear selection are employed
Special purpose synchronous motors with straight drive supplied at appropriate high frequency are used for high speed
Complex duty cycle drives needs special high accuracy servo system
