In equipment such as electric vehicles, electric tricycles, electric vehicles, washing machines, etc., motors are indispensable. less equipment. Ordinary motors have a high speed. In order to obtain a suitable output speed, the motor needs to be decelerated in practical applications. At present, the commonly used method is to transmit the motor to the reducer and decelerate through the first-stage pulley, and set a first-stage pulley in the reducer. Or multi-stage gear reduction device to complete the deceleration of a certain speed ratio. This structure is not only complicated, but also takes up a lot of space. In order to solve this technical problem, there are currently some proposals to remove the pulley and directly connect the motor and the reducer. Since the motor body and the reducer are still relatively independent, the motor body and the reducer need to occupy installation space respectively, and the structure is not enough. Compact and still bulky.
