Motor rotor plate, motor rotor having motor rotor plate, and motor having motor rotor

A motor rotor comprising a plurality of motor rotor plates stacked together, each of the plurality of motor rotor plates comprising:

• a rotating shaft;
• a connecting portion coupled to the rotating shaft to drive the rotating shaft to rotate;
• and
• a plurality of electrode portions used to wind a coil, the plurality of electrode portions spaced around the connecting portion at a same interval, one end of each electrode portion coupled to the connecting portion, and another end of each electrode portion extending outward in a radial direction of the connecting portion, wherein a width of each electrode portion gradually increases along the radial direction of the connecting portion to increase an area of the electrode portion, thereby increasing a magnetic flux, so that an electric current of the coil is reduced while maintaining a certain rotation speed to reduce heat generation.

A motor comprising:

• a housing;
• a motor stator fixed in the housing;
• a motor rotor;
• and
• a rotating shaft fixed on the motor rotor and rotationally coupled to the housing, the motor rotor comprising a plurality of motor rotor plates stacked together, each of the plurality of motor rotor plates comprising:
• a rotating shaft;
• a connecting portion coupled to the rotating shaft to drive the rotating shaft to rotate;
• and
• a plurality of electrode portions used to wind a coil, the plurality of electrode portions spaced around the connecting portion at a same interval, one end of each electrode portion coupled to the connecting portion, and another end of each electrode portion extending outward in a radial direction of the connecting portion, wherein a width of each electrode portion gradually increases along the radial direction of the connecting portion to increase an area of the electrode portion, thereby increasing a magnetic flux, so that an electric current of the coil is reduced while maintaining a certain rotation speed to reduce heat generation.
