In order to further improve the performance of the permanent magnet DC motor for K mechanism, certain improvement measures are needed in structural design and fabrication. For example, when the number of stator slots and the number of rotor poles form a specific proportional relationship, concentric windings can be used, thereby reducing manufacturing costs, improving production efficiency, reducing copper wire usage and copper consumption, and improving motor efficiency.
In this way, after the structural improvement, when the stator slot number and the number of rotor poles form a specific proportional relationship, the straight slot structure can be directly adopted, thereby further reducing the manufacturing cost, improving the production efficiency and the motor efficiency. The permanent magnet DC motor comprises a stator and a rotor, the stator is provided with a slot, the slot is embedded with a winding, and the rotor is provided with a permanent magnet pole, wherein each winding is embedded in two adjacent slots. And each slot contains only one active edge of one winding.
Therefore, the permanent magnet DC motor of the K mechanism can not only start and run normally, but also has simple processing, and can be mechanically and automatically disconnected, which has high production efficiency and low cost. 2. The winding end is line-saving, the copper consumption is low, and the motor efficient.
