The invention discloses an enhanced heat dissipation type double-frequency-conversion integrated variable frequency motor, and relates to the technical field of motors. The motor comprises a motor body and a protective shell. A frequency converter fixing rod is fixedly connected to the inner circumferential side face of the protective shell. A frequency converter host comprises a frequency converter host box; one end of a mini rotating shaft is fixedly connected with a mini fan; a double-frequency-conversion control panel is fixedly installed in the frequency converter host. cylindrical flow guide holes are formed in the peripheral side surface of the motor body along the axial direction; and the interior of the cylindrical flow guide holes communicates with the interior of the protectiveshell. Through the design of the protective shell, the frequency converter host, the frequency converter host box, the main rotating shaft, the mini rotating shaft and the double-frequency-conversioncontrol panel, integration of the motor and the frequency converter can be achieved, independent frequency conversion control over the motor and the cooling fan is facilitated, a large amount of usingspace is saved, the production cost is greatly reduced, and meanwhile, the efficient heat dissipation effect of the motor is effectively ensured.

Description

technical field [0001] The invention belongs to the technical field of electric motors, and in particular relates to a heat dissipation-enhanced double-frequency conversion integrated frequency conversion motor. Background technique [0002] A motor is a device that converts electrical energy into mechanical energy. It uses energized coils to generate a rotating magnetic field and acts on the rotor to form a magnetoelectric force rotating torque. Motors are divided into DC motors and AC motors according to the different power sources used. Most of the motors in the power system are AC motors, which can be synchronous motors or asynchronous motors. The motor is mainly composed of a stator and a rotor. The direction of the current-carrying wire in the magnetic field is related to the direction of the current and the direction of the magnetic induction line. During the use of the motor, it is often necessary to adjust the motor speed according to actual needs, which requires ...
