5. 내 용 :





An inherent property of slotted permanent magnet motors is the


presence of cogging torque. Sometimes its existence is a welcomed property, but in most applications it is a nuisance. Left uncontrolled, it can cause mechanical vibration, noise, position and velocity errors. It is also difficult to predict accurately. This presentation explores the cause of cogging torque, its


characteristics, how it can be predicted, and ways it can be minimized.
