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
