Description

technical field [0001] The invention relates to the field of motors, in particular to a brushless motor with a threaded adjustment lock shaft structure. Background technique [0002] The brushless motor is a motor with precise speed control. It controls the direction of the driving current through a controller to realize the change of the direction of the magnetic field to drive the motor to run. [0003] Existing brushless motors are all in the form of a single motor, and its rated power and other parameters are still determined during manufacture. In use, it can only output power below the rated power externally. When the power demand on site increases, it can only Replacing a new motor with higher power does not mean that the original motor is scrapped, but also needs to remove the original connection structure to replace it, which is very troublesome; sometimes the power consumption of two similar locations of power consumption fluctuates, often There is a surplus of po...

Problems solved by technology

In the prior art, the clamping spring and the wave ring are generally used to adjust the locking degree through a gasket of a certain thickness. During assembly, it is necessary to repeatedly adjust and replace the gasket with a suitable thickness. Adjustment, time-consuming and laborious assembly, unable to finely control the degree of locking
