Title:
MOTOR, POWER DEVICE, AND BULLDOZER
Document Type and Number:
WIPO Patent Application WO/2018/159349
Kind Code:
A1
Abstract:
An embodiment of the present invention provides a motor, a power device, and a bulldozer. The motor is provided with: a rotating shaft extending along the central axis line; a cylindrical rotor core provided on the outside of the rotating shaft in the radial direction; a rotor having two disc-shaped weight plates provided at both ends of the cylindrical rotor core in the shaft direction; and a stator disposed facing the rotor in the radial direction. The radius of the weight plate is smaller than the radius of the rotor core, and the difference between the radius of the rotor core and the radius of the weight plate is larger than the air gap between the outside of the rotor core in the radial direction and the inside of the stator in the radial direction. According to the embodiment of the present invention, the iron loss on the weight plate can be reduced in an easy-to-use method, thereby enabling the total efficiency of the motor to be improved.
