Problems solved by technology

[0002] At present, the frame used in metallurgical and lifting medium-sized motor fixing devices on the market is generally made into a hollow cylinder shape, and the outer surface of the cylinder is provided with heat sinks along the axis of the frame. The cooling effect of this type of frame is not good. , and the overall volume is relatively large; the junction box pile on the outer surface of the existing motor base blocks all the cold wind brought by the tail end of the cooling blade of the base, which easily causes the local temperature rise of the motor and reduces the service life of the motor
In addition, the machine base is prone to blade breakage during the entire motor assembly and transportation process, which affects the normal use of the machine base

Embodiment Construction

[0018] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0019] Such as figure 1 The shown motor frame includes the frame body 1 and the frame cooling blades 18 provided on the surface of the frame body 1, the frame body 1 is a hollow cylinder, and the front end face 16 and the rear end face 17 of the frame body 1 are Four end caps 13 are evenly arranged in the circumferential direction, and a connected internal circulation ventilation channel 14 is provided between the two end caps 11 on the front end face 16 and the rear end face 17 on the same column busbar. The sub 13 strengthens the rigidity of the machine base, and the internal circulation ventilation channel 14 provides 4 internal circulation passages for the motor, which can better help the motor to dissipate heat. The outer surface of the internal circulation air duct 14 is provided with air duct heat dissipation blades 11 arranged in parall...

Abstract

The invention relates to the technical field of motors, in particular to a motor frame adaptive to a middle-scale motor for metallurgy and crane. The motor frame comprises a frame body and frame heat radiating blades arranged on the surface of the frame body; the frame body is a hollow cylinder; the circumferences of the upper edge of the front end surface and rear end surface of the frame body are provided with four end cover bosses; a through inner circulating ventilation channel is arranged between two end cover bosses of the front end surface and rear end surface of the same bus of the cylinder, and the outer surfaces of the inner circulating ventilation channels are provided with parallel ventilation channel heat radiation blades along the cylinder buses. The motor frame is high in rigidity, the heat of the motor can be radiated better, and the partial temperature of the motor is dropped.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a motor frame suitable for medium-sized motors used in metallurgy and hoisting. Background technique [0002] At present, the frame used in metallurgical and lifting medium-sized motor fixing devices on the market is generally made into a hollow cylinder shape, and the outer surface of the cylinder is provided with heat sinks along the axis of the frame. The cooling effect of this type of frame is not good. , and the overall volume is relatively large; the junction box pile on the outer surface of the existing motor base blocks all the cold wind brought by the tail end of the cooling blade of the base, which easily causes the local temperature rise of the motor and reduces the service life of the motor .
