In the winding process of formula winding, the width of rebate of stator core wire casing cannot be too small, otherwise centralized winding can not be wrapped in
On stator core magnetic pole.If the width of rebate of stator core wire casing is larger, the cogging torque of motor can increase, to increase
Generator loss reduces motor performance.Therefore common brushless direct current motor and common permasyn morot majority use
Fractional-slot winding reduces cogging torque.The major defect of fractional-slot winding is:Slot number has hard constraints, armature anti-with selection of number of poles
It answers magnetomotive force to contain a large amount of harmonic waves, rotor eddy current loss and noise can be caused.If there is a kind of motor stator technology, do not influencing
Under the premise of centralized winding technique processing, reduce the width of rebate of stator core wire casing or the notch of stator core wire casing
Width is zero, i.e., the stator core wire casing is closed slot, then while reducing cogging torque, brushless direct current motor or permanent magnetism
Synchronous motor can use integer slot winding, slot number and pole when increasing brushless direct current motor or permasyn morot design
Several ranges of choice, and improve motor performance.
The stator core wire casing of asynchronous motor will produce slot ripples, and harmony wave generates additional torque, causes electromagnetism
Vibration and noise.The method of asynchronous motor generally use rotor chute, the electricity for making harmony wave incude in rotor bar
Kinetic potential is partially offset, and reduces the additional torque that harmony wave generates.Therefore, reduce asynchronous motor stator winding slot of core
The width of rebate of width of rebate or stator core wire casing is zero, i.e., the stator core wire casing is closed slot, is conducive to asynchronous electricity
Motivation reduces the additional torque that harmony wave generates, and improves motor efficiency.
