Abstract

The invention discloses a permanent magnet direct drive roller motor with heat dissipation and braking functions, which comprises a main shaft, a stator, a mounting seat and a rotor, and is characterized in that the main shaft is fixed on the mounting seat, the stator is fixed on the main shaft, the rotor is sleeved outside the stator, a braking device is fixed at two ends of the rotor, and a cooling device comprises a water cooling device and an air cooling device; the water cooling device is located in a cavity between the stator and the main shaft and wound on the main shaft, and the air cooling device is installed at one end of the main shaft and axially parallel to the main shaft. The device has the advantages that the problem of heat accumulation of equipment is solved by utilizing the water cooling device mounted in the main shaft and the air cooling device mounted on the side surface of the main shaft and blowing air into the main shaft, and meanwhile, the problem that the equipment cannot be stopped quickly when being closed is solved by utilizing the brake devices mounted on the two sides of the edge of the rotor.

Description

technical field [0001] The invention relates to the technical field of electric drive systems, in particular to a permanent magnet direct drive drum motor with heat dissipation and braking functions. Background technique [0002] The permanent magnet direct drive drum has a simple mechanism and reliable operation. It is suitable for high-torque scenarios and is widely used in mining and belt transportation. However, the coils on the inner stator of the external drum rotor will generate heat during the working process. The accumulated heat will cause the demagnetization of the permanent magnets fixed inside the drum rotor. At the same time, because the mass of the belt transport is relatively large, the equipment cannot be stopped quickly due to inertia. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is the problem that the permanent magnet direct drive drum accumulates heat during operation and cannot be stopped quickly when t...
