EFFECT OF SKEWING ON THE COGGING TORQUE IN INDUCTION MACHINES

Electric Machines & Power Systems, 1994
ABSTRACT This paper presents a simplified method to predict the cogging torque in induction machines including the skewing effect An equivalent circuit including die effect of both slot harmonics and rotor skewing is developed. A special attention is paid to study the skewing effect on the machine behaviour especially at starting instant. Moreover, the

Study of cogging torque in permanent magnet machines

IAS '97. Conference Record of the 1997 IEEE Industry Applications Conference Thirty-Second IAS Annual Meeting, 2002
Cogging torque is produced in a permanent magnet machine by the magnetic attraction between the rotor mounted permanent magnets and the stator. It is an undesired effect that contributes to the machines output ripple, vibration, and noise. This paper analyzes various cogging torque minimization techniques as applied to a permanent magnet machine used ...

Study of Cogging Torque in Permanent Magnet Machines

Electric Machines & Power Systems, 1999
Cogging torque is produced in a permanent magnet machine by the magnetic attraction between the rotor-mounted permanent magnets and the stator. It is an undesired effect that contributes to the machines' output ripple, vibration, and noise. This paper analyzes various cogging torque minimization techniques as applied to a permanent magnet machine used ...
