Description

technical field [0001] The invention relates to the field of motor manufacturing and assembly, in particular to a hanging rail DC brushless fan motor. Background technique [0002] For the hoisting of objects or devices, motors are the most commonly used power output devices. Most of the motors used in the existing hoisting process are three-phase asynchronous motors. The existing three-phase asynchronous motor has certain deficiencies in use. [0003] First of all, its starting torque is not large, and when the load is large, it is difficult to meet the demand for starting; secondly, the large torque is not large, and short-term overload loads are prone to occur during the driving process; in addition, it uses three-phase current, and its voltage Higher, the control process is more complicated, it is not easy to control the speed, the application is limited, and the safety is not as good as the DC motor. Contents of the invention [0004] The object of the present inve...
