AI Technical Summary
The existing flat wire motors with 2 slots per pole per phase have high winding complexity and poor balance, which leads to circulating current and abnormal temperature rise, affecting the normal use of the motor.
The double short-pitch balanced winding structure is adopted. By setting rectangular conductors in the stator slots, the number of slots per pole per phase is specified to be an integer multiple of 2, and the number of branches per phase is an integer multiple of 2. Different span methods are used to connect the windings at one end and the other end of the stator slots, which simplifies the winding process and ensures a balanced distribution of conductor layers.
This reduces the difficulty of winding, avoids the generation of circulating current and abnormal temperature rise, and ensures the normal operation and stable performance of the motor.
