Abstract

The invention discloses an operation mechanism of a motor. The operation mechanism comprises an auxiliary electronic switch, a controller, an angle detecting unit, a voltage detecting unit, a current detecting unit, a serial communication interface, a display unit, a data storage unit and a control button. The angle detecting unit is used for detecting the rotating angle of an output shaft of a motor speed reducer. The auxiliary electronic switch comprises a signal processing circuit and a power amplifying circuit, and the signal processing circuit comprises a TTL open collector six-normal-phase high-voltage driver, a TTL open collector six-reverse-phase high-voltage driver and multiple power amplifiers. The TTL open collector six-reverse-phase high-voltage driver is connected with the TTL open collector six-normal-phase high-voltage driver, and the power amplifiers are connected with the TTL open collector six-reverse-phase high-voltage driver. The TTL open collector six-normal-phase high-voltage driver is connected with the motor control end of the controller. The power amplifying circuit comprises multiple sets of solid relays. The operation mechanism is simple in circuit, reasonable in design, convenient to wire, good in using effect and capable of solving various problems existing in an existing operation mechanism of the motor.
