Description
Technical field
A kind of machine winding is the utility model is related to, more particularly, to a kind of nested winding for non-gullet motor.
Background technology
For slotless magneto, motor main parts size includes stator core, stator winding, rotor magnetic steel and turns
Axis, wherein winding are the core components of slotless magneto.
Traditional hollow-cup motor (such as US.4,5543,507) is since winding is directly exposed to the open air in air-gap field, at a high speed
Very big eddy-current loss can be generated in rotating magnetic field, sees Fig. 1, needs use thinner when designing drag cup winding for this
Copper wire winding coil, based on this demand, in order to make full use of the rotor space of motor, it is necessary to using multiply and around side
Case coiling, if but traditional lap winding scheme using multiply scheme coiling, and around coil between can produce one
Phase difference, if by two coils from parallel connection of coils, then the phase difference can cause internal circulation, then cause loss.
