The application discloses an explosion-proof high-speed
permanent magnet motor and relates to the technical field of motors. The motor shell is provided with end covers at two ends, high-precision bearings are used to install the shaft, so that
dynamic balance and
low friction during high-speed operation are ensured, an
oil storage groove is arranged on the end cover, the
oil storage groove is filled with lubricating oil, and through a rotating speed adjusting unit and a temperature adjusting unit, adjusting liquid in the groove is adjusted to flow into the
oil storage groove according to the rotating speed and temperature change of the shaft, so that the adjusting liquid pushes the
extrusion block to move, the lubricating oil in the oil storage groove flows into the bearing interior through the inflow channel of the bearing, and the bearing is supplemented with
lubrication, a reset spring is arranged between the
extrusion block and the oil storage groove, so that the
extrusion block can be reset when the rotating speed and temperature of the shaft recover, and the explosion-proof effect of the motor is enhanced through the arrangement of the explosion-proof mechanism.
