Slip of Induction Motor with Frequency Speed Control

  • Received Date: 01 Dec 2004
  • Publish Date: 25 Feb 2006
  • Based on the torque-speed characteristic curve of induction motors,analyses were done on changes in slip with an variation in frequency when an induction motor drives different kinds of loads,including those with constant torque,constant-maximum torque,variable torque(except fans and pumps) and constant power,as well as fans and pumps.The formulas to calculate the slip and the speed under different frequencies and loads were presented.The analyses show that slip changes with an change in frequency for an induction motor with frequency speed control.This conclusion does not support the viewpoint that the slip of an induction motor with frequency speed control is constant.
