Problems solved by technology

[0002] Because many of the rotor slots in the existing motor rotor structure are odd slots instead of even slots, some problems are prone to occur in the process of winding the motor rotor, such as: ① Symmetrical winding cannot be used; ② If a single flying fork is used Winding, the windings are superimposed in sequence according to the winding order. After the winding is completed, the balance amount is biased towards the direction of the last coil, which increases the dynamic balance amount. In the dynamic balance production process, the large dynamic balance amount leads to a decrease in production efficiency;③ In addition, due to the large amount of dynamic balancing, the amount of heavier balancing glue to be used increases, resulting in an increase in cost; ④ Due to the excessive amount of balancing glue used, there is a risk that the balancing glue will fall off or rub against the stator

Abstract

The present invention discloses an odd number slot motor rotor and a winding method thereof. The odd number slot motor rotor comprises a rotor slot, a commutator, a first coil winding and a second coil winding, proper distances k between adjacent coil starting slots are selected according to the number of the rotor slots, distances between adjacent coil starting hooks are determined according to the number of hooks of the commutator and the distances k, a starting slot of a first coil of the second coil winding is taken as a starting slot of a second coil of the first coil, and a dual-layer coil winding mode is employed to performing winding of the first coil winding and the second coil winding. The odd number slot motor rotor and the winding method thereof employ double-kick winding to effectively reduce the dynamic balance, are high in production efficiency, reduce the balance glue amount, reduce the cost, are low in motor energy loss, low in service life and low in risk of balance glue shedding or friction of a stator.
