Description

A small motor assembly platform

technical field

Background technique

At present, small motors with a power level of tens of kilowatts and a weight of hundreds of kilograms have been widely used in various industries, with a huge market and many manufacturers. However, there are still some manufacturers whose production facilities are relatively backward in the field of manufacturing, and the degree of automation of the equipment is not high. The rotor is directly moved into the horizontal stator for assembly. Although this method does not need to move the motor stator, it is easy to cause damage to the stator winding and damage the bearing during assembly, and the operation of aligning the rotor to the center is extremely inconvenient. If the vertical assembly method is used, the above problems can be effectively overcome, but the motor stator needs to be turned over 90° so that the open end of the motor is vertically upward during assembly. However, there are also problems such as inconvenient operation, high labor intensity, and low efficiency.
