Abstract

According to the double-rotor brushless motor for the pulsator washing machine and the mounting structure of the double-rotor brushless motor in the washing machine, an inner coil and an outer coil are arranged on the inner side and the outer side of a stator respectively, a closed magnetic loop is formed by a magnetic field generated by the inner coil and an inner rotor, and the inner rotor is driven to rotate; a closed magnetic loop is formed by a magnetic field generated by an external coil and the outer rotor to drive the outer rotor to rotate, so that independent driving control of the inner rotor and the outer rotor is achieved, and due to the fact that the double-rotor brushless motor is provided with the two rotors capable of achieving independent output, when the double-rotor brushless motor is adopted to drive an impeller and an inner barrel of the impeller washing machine, a clutch can be omitted, and the cost is reduced. The impeller is directly and fixedly connected with the inner rotating shaft of the inner rotor, and the inner barrel is directly and fixedly connected with the outer rotor, so that the overall height and the gravity center height of the washing machine can be reduced, the working stability of the washing machine is improved, noise caused by clutch switching and transmission is eliminated, and the user experience feeling is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of motors, and in particular relates to a double-rotor brushless motor for a pulsator washing machine and its installation structure in the washing machine. Background technique [0002] The pulsator washing machine is a vertical washing machine, which mainly includes a shell, an outer cylinder fixedly connected in the shell for holding water, an inner cylinder rotatably connected in the outer cylinder for holding clothes, and a rotatably connected bottom surface of the inner cylinder for stirring The water flow and the pulsator of the clothes and the driving mechanism that drives the inner cylinder and the pulsator to rotate. The driving mechanism used in the traditional pulsator washing machine includes a motor and a clutch, and the clutch is usually used to connect the motor output shaft and the inner cylinder and the pulsator. The clutch needs to be installed, so a high installation space for the drive m...
