The invention discloses a plateau high-altitude motor reversing power switching device, and belongs to the field of motors. The plateau high-altitude motor reversing power switching device comprises a control box, a motor box, switching mechanisms, a power shaft, an output shaft, a rotating disc and a transmission mechanism, a switching cavity is formed in the control box, the motor box is arranged in the switching cavity and can move left and right, sliding cavities are formed in the upper side and the lower side of the switching cavity in a communicating mode, and the switching mechanisms are arranged in the upper sliding cavity and the lower sliding cavity. The switching mechanism is used for controlling the motor box to move left and right, a power motor is fixedly arranged in the motor box, the power shaft is in power connection with the right end of the power motor, a transmission cavity located on the right side of the switching cavity is formed in the control box, and the right end face of the power shaft extends into the transmission cavity. According to the scheme, the meshing mode of the transmission straight gear can be changed, so the positive and reverse rotating states of the output shaft re controlled, a reversing mode of a traditional brush motor is changed, and the service life of the electric brush of the positive and negative rotation motor is prolonged.
Description
technical field [0001] The invention relates to the field of electric motors, and more specifically, relates to a commutation power switching device for high-altitude and high-altitude electric motors. Background technique [0002] When ordinary engines are used directly on plateaus or high altitudes, due to the large difference in air pressure, there are serious problems in power loss and service life. [0003] The motor operates at high altitude, due to the low air pressure and poor heat dissipation conditions, that is, the loss will increase and the operating efficiency will decrease, and the altitude is not good for the power commutation of the motor, which will affect the life and performance of the carbon brush material, and more seriously It will cause the motor to burn out in a short time. Contents of the invention [0004] 1. technical problem to be solved [0005] Aiming at the problems existing in the prior art, the object of the present invention is to provi...
