TH43003B - Brushless DC motor for washing machine - Google Patents

Abstract

DC60 (08/10/57) brushless motor in a washing machine that includes a stator with windings. Coupled with The top frame and the rotor with the undercarriage frame are all formed from Metal in order to Covering the outer perimeter and underside of the stator, a number of magnets fit into the inner wall of the lower frame at a constant distance opposite to the rising stator and support parts. Figure is one set And in the middle part of the frame, the bottom frame that is connected with Drive shaft for transmission Of the rotational force of the lower frame to the drive shaft, that is, it allows for a smooth heat dissipation and smooth cooling from the motor. And to make karma The manufacturing method and the time used are shorter, the brushless motor in the washing machine. Containing The stator with coils coupled to the top frame and the rotor with the stator frame are all formed from metal to cover the outer perimeter and southern part of the stator. Then a number of magnets fit into The inner wall of the frame The lower frame at a constant distance opposite to the stator and the support parts that are formed as one set. And in the middle part of the undercarriage that is coupled to the drive shaft for transmission of the lower frame rotational force to the drive shaft, that is, it allows the Distribution of Overheating and smooth cooling from the motor And shortening the karma, production methods and time
