Efficient heat dissipation motor for wall breaking machine and control method

Abstract

The invention discloses an efficient heat dissipation motor for a wall breaking machine and a control method, which belong to the technical field of wall breaking machine motors. The motor comprises amotor shell, a heat dissipation shell and a supporting frame, wherein the supporting frame is fixed to the outer side of the motor, a port is connected with the inner wall of the heat dissipation shell, a rotating shaft is installed on the motor, the surface, located between the motor and the heat dissipation shell, of the rotating shaft is sleeved with an outer heat dissipation device, and airflow generated by the outer heat dissipation device reduces the temperature of the outer surface of the motor. According to the efficient heat dissipation motor for the wall breaking machine and the control method, the gap between the heat dissipation shell and the motor increases the flow velocity of airflow, so that the high-speed airflow passes through the cooling fins in the radial direction todrive the overflowing temperature of the surface of the motor, and external cooling is achieved; the internal temperature of the motor is reduced by cooling the interior of the rotor, the external temperature of the motor is reduced by matching with the fan, and the heat dissipation effect is improved by utilizing the internal and external synchronous working state.

[0003] The patent document (CN201811584295.6) discloses a counter-rotating motor and a wall-breaking machine. The counter-rotating motor of the wall-breaking machine is provided with two sets of inner and outer windings and rotors, and a set of inverters is used to synchronously control the outer winding and the inner The winding can save brushes, reduce noise, and improve the life of the motor. At the same time, because there is no need for two sets of inverters, the cost is lower and the control is simpler. However, the cooling effect of the counter-rotating motor is poor, and long-term revolution will affect the motor. At the same time, the air moisture content near the motor in the wall breaking machine is relatively large, which will affect the normal use of the motor for a long time
