On.
Common brushless direct current motor and common permasyn morot are using centralized winding and p-m rotor.It is concentrating
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 be will 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 and selection of number of poles have hard constraints, and armature is anti-
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 can generate slot ripples, and harmony wave generates additional torque, causes electromagnetism
Vibration and noise.Asynchronous motor generallys use the method for rotor chute, the electricity for incuding harmony wave 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
