Double-rotor motor

Abstract

The invention discloses a double-rotor motor which comprises a stator (1), an outer rotor (2) is arranged on the outer side of the stator (1), an outer rotor shaft is arranged on the outer rotor (2),an inner rotor (3) is arranged on the inner side of the stator (1), and an inner rotor shaft is arranged on the inner rotor (3). The stator (1) comprises an annular stator outer framework (10), and aplurality of first magnetic poles (11) distributed in the circumferential direction are arranged in the stator outer framework (10). The washing machine has the advantages that clothes are easy to clean, washing damage is not prone to occurring, and energy consumption is low.

Description

technical field [0001] The invention belongs to the field of washing machine motors, in particular to a double-rotor motor for washing machines. Background technique [0002] The structure of the motor used in the existing washing machine includes a stator, a rotor is arranged in the stator, a rotor shaft is arranged on the rotor, and a motor cover that is passed through by the rotor shaft is arranged on both sides of the stator, and the motor cover is used to fix the rotor shaft. The installation structure of the motor in the washing machine, the stator is fixed to the base of the washing machine through the motor cover, the rotor is fixed to the pulsator of the washing machine through the rotor shaft, the magnetic repulsion between the stator and the rotor drives the rotor to rotate, thereby driving the pulsator to rotate , the pulsator drives the clothes to be stirred in the outer bucket for cleaning. In order to increase the rotation speed of the pulsator and make the cl...

Problems solved by technology

[0003] After long-term research by the applicant, it was found that because the outer tub is fixed, the clothes are only driven by the pulsator, the power is single, and the clothes are driven by a unidirectional and constant rotational force. For some very dirty clothes, the rubbing force is too low and it is difficult to clean Clean, for some clothes that are easily deformed (such as wool clothes), the rubbing force is too large, and it is easy to be washed (washed and deformed)

In addition, there is a large resistance in the gearbox, and there is a relatively large loss in the process of transmitting the driving force of the motor to the pulsator, resulting in a large energy consumption of the washing machine

[0004] Therefore, the washing machine using the existing motor has the disadvantages that the clothes are difficult to clean or easy to wash, and the energy consumption is relatively large.
