Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings.

[0017] like figure 1 As shown, a high heat dissipation explosion-proof three-phase asynchronous motor includes a frame 7 with a cylindrical cavity on the inner wall, and a front end cover 2 and a front bearing outer cover 1 are sequentially installed on the front end of the frame 7 from the rear to the front. , the rear end cover 5 and the rear bearing outer cover 6 are installed in sequence from the front to the rear at the rear end of the machine base 7, and the stator core 3 is installed in the machine base 7, and the stator core 3 manufactured after lamination of punching sheets In the groove on the outer circumference (formerly a buckle structure), there is a rib plate (marked in the figure), the thickness of the rib plate is equal to the depth of the groove, and the outer surface of the rib plate and the outer surface of the stator core 4 Located on a circumfere...

Abstract

The invention discloses a high-heat-dissipation explosion-proof three-phase asynchronous motor. A stator iron core is installed in a motor base. A rotor matched with the stator iron core is installed in the stator iron core. End rings are respectively fixed on two ends of the rotor. A plurality of rotor fan blades are arranged along the peripheral directions of the two end rings. The widths, along the peripheral direction, of the rotor fan blades are forwards or backwards gradually reduced. Rib plates are arranged in grooves formed in the outer periphery of the stator iron core, and the thickness of each rib plate is equal to the depth of each groove. The outer diameter of the stator iron core is equal to the diameter of a cylindrical cavity of the motor base. The high-heat-dissipation explosion-proof three-phase asynchronous motor solves the problems that a V-shaped ring on a bearing of an original motor is poor in protection capability, wet dust can easily enter the inner part of the motor through a contact surface between the V-shaped ring and the bearing, and after a long time, lubricating grease loses effectiveness and an explosion-proof surface is damaged.

Description

technical field [0001] The invention relates to the technical field of an explosion-proof motor, in particular to a high heat dissipation type explosion-proof motor. Background technique [0002] Explosion-proof motors usually use relatively thick flat end covers to meet the explosion-proof strength requirements. Although this meets the explosion-proof requirements, its structure is relatively bulky, and it affects the heat transfer inside the motor. It is very troublesome to disassemble and assemble, and the manufacturing cost is also high. IC411 cooling method The rotor inside the motor is in close contact with the stator core and there is no radial air passage. The heat generated inside the motor can only reach the outer surface of the machine base and end cover through multi-layer transfer, and finally exchange heat with the surrounding air. Heat dissipation; the stator core is made by stacking multiple punching sheets. Its outer surface is not neat at first and cannot f...
