Problems solved by technology

But there are the following disadvantages: 1. The disengagement of the conical brake device is realized by the axial component force produced by the conical rotor. Therefore, when the conical brake motor is frequently braked, the rotor shaft as a whole frequently The axial movement of the ground affects the strength and life of the whole machine, and the noise is relatively large; 2. The rotor and stator cores of the conical brake motor are both conical, because the diameter of each piece of the core is different , so that during manufacture, t

Abstract

The new type of crane motor includes rotor shaft, cylindrical rotor, stator, side magnetic device, compression spring, conic brake and fan. The side magnetic device and the conic brake cooperate, that is, the side magnetic device generates the axial play force moment of the conic brake and there is no need of complete play of the rotor shaft. The present invention has reliable braking, raised rotor shaft strength, long rotor shaft life, low noise and other features.

Description

technical field [0001] The invention relates to a novel hoisting motor, which is applied to hoisting machinery. Background technique [0002] At present, there are two kinds of motors commonly used in hoisting mechanisms in China. One is a conical brake motor, which uses a conical rotor and a conical brake device, which has the characteristics of large braking torque and reliable braking. But there are the following disadvantages: 1. The disengagement of the conical brake device is realized by the axial component force produced by the conical rotor. Therefore, when the conical brake motor is frequently braked, the rotor shaft as a whole frequently The axial movement of the ground affects the strength and life of the whole machine, and the noise is relatively large; 2. The rotor and stator cores of the conical brake motor are both conical, because the diameter of each piece of the core is different , In this way, during manufacture, the punching sheet adopts ...
