The heat dissipation motor comprises a motor main body, an
air cooling mechanism and a liquid cooling mechanism, the motor main body comprises a shell, a
stator, a rotor, a rotating shaft and a driver, the inner part of the shell is provided with a first chamber and a second chamber, the
stator and the rotor are both arranged in the first chamber, and the shell is provided with a ventilation opening; the
air cooling mechanism comprises fan blades, the fan blades are fixedly connected to the rotating shaft and located at the ventilation opening, the fan blades are provided with a first
air channel and a second
air channel, the second
air channel surrounds the first air channel, a plurality of first blades are arranged in the first air channel, a plurality of second blades are arranged in the second air channel, and the rotating direction of the second blades is opposite to that of the first blades; the liquid cooling mechanism comprises a radiator, a refrigerator and an
oil pump, the radiator is arranged on the driver and used for absorbing heat of the driver, the
oil pump is connected with an oil
pipe, the radiator and the refrigerator are in closed-loop connection through the oil
pipe, and the refrigerator is used for cooling oil in the oil
pipe. The heat dissipation efficiency is improved; and the
energy consumption is reduced.
