There are many reasons for the torque fluctuation of Brushless DC motor, which can be divided into the following aspects: torque fluctuation caused by electromagnetic torque generation principle, torque fluctuation caused by current commutation, and torque fluctuation caused by cogging effect. In addition, there are torque fluctuations caused by armature reaction and motor process defects. They are described as follows:

?The programmable controller is the core component of the equipment. It cooperates with the manipulator, pneumatic control elements and executive accessories to complete the functions of automatic wire arrangement, automatic winding, automatic wire cutting, automatic loading and unloading of framework, etc. this model has high production efficiency and greatly reduces the labor cost. Only one operator is required for……

The existing technology has the following shortcomings: 1. In the process of using the existing winding machine, the coil of the motor rotor is mainly wound by semi-automatic equipment. For products with a large number of coil turns, the production efficiency is too low. To meet the capacity demand, multiple equipment need to be added, and the production cost is high;

1. Hardware problems: typical problems are the tension and induction of the tensioner. The tension setting of the tensioner is unreasonable, there are burrs at the place where the wire passes, and the lubrication is not enough to jam the wire, resulting in wire breakage.

?Brushless DC motor is difficult to match in variable speed applications because of its unique performance and simple control. Although AC motor and control have recently developed to compete with many of its advantages, brush DC motor is still common in many industries, especially in mechanical equipment, automotive electronics, home intelligence, automatic doors and windows and so on.

Many times, industrial and manufacturing plants need spare motor inventory, so the environmental problem of motor storage is particularly important. Motor damage may mean missed deadlines, employee downtime or deteriorated products. These enterprises rely on their motor work, so having a spare motor on hand can help reduce long-term costs.
