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
