Abstract

The invention provides a permanent magnet adjustable-speed motor for oil field equipment. Relates to the technical field of permanent-magnet motors. A flow passage is arranged in radiating ribs of the casing, transverse through holes and a central hole between the two transverse through holes are arranged on a motor shaft, the rotor is fixedly connected with a centrifugal spiral blade, a rear filter screen is arranged on the rear side of the fan cover, the fan cover extends forwards to the position of the front end cover, and a front filter screen is arranged at an annular space position between the fan cover and the front end cover. The fan has the following beneficial effects that the fan cover covers the radiating ribs to form a forced ventilation condition, and air flows through the radiating ribs orderly when the fan blades rotate, so that the utilization rate of overflowing air is increased; and meanwhile, dust, rain and snow in the external environment can be prevented from entering and accumulating on the heat dissipation ribs to reduce the heat dissipation performance by covering the fan cover and arranging the front and rear filter screens.

Description

Technical field: [0001] The invention relates to the technical field of permanent magnet motors, in particular to a permanent magnet speed-regulating motor used in oil field equipment. Background technique: [0002] The permanent magnet speed control motor has become an important development direction of new high-efficiency and energy-saving motors. However, the practice shows that due to the limitation of the cooling structure of the existing permanent magnet speed control motor, the cooling structure of the existing permanent magnet speed control motor mainly adopts its own fan cooling. In this way, the rotating shaft drives the fan to blow the cooling air to the cooling ribs on the outer surface of the machine base through the holes of the windshield, and then take away the heat generated by the permanent magnet motor through the cooling ribs. This cooling method cannot remove the heat generated inside the permanent magnet speed control motor The heat is fully taken away,...
