How to choose enameled wire material for brushless motor stator coil needle winding machine? What are the tips and methods?

When choosing the enameled wire for brushless motor winding machine, it is really necessary to consider many aspects in detail to ensure that the comprehensive performance of the motor reaches a good state. So how to choose enameled wire for brushless motor winding machine? What are the techniques and methods, Vacuz will introduce it to you!

First, the motor type and power requirements of the exact match

1. Motor type: first of all, we should clarify the specific type of brushless motor, such as outer rotor or inner rotor, which directly affects the winding design and the choice of enameled wire. Different structure of the motor on the enameled wire temperature resistance, voltage resistance and conductivity requirements are different.

2. Power requirements: high power motors on the conductive properties of enameled wire and high temperature resistance to put forward higher requirements. Therefore, in the selection of the enameled wire need to pay special attention to the current carrying capacity and thermal stability, to ensure that the motor can still run stably under high load.

Second, the enameled wire material and performance of the depth of consideration

1. Material selection: copper enameled wire has become the first choice for most brushless motors due to its excellent conductivity and corrosion resistance. Polyimide (PAI) and polytetrafluoroethylene (PTFE) enameled wire is suitable for specific high temperature, high humidity or corrosive environments due to its special properties.

2. Performance evaluation: Heat resistance, electrical conductivity and insulation properties are key indicators for assessing the quality of enameled wire. Selection needs to ensure that these properties meet or exceed the design requirements of the motor to protect the long-term stable operation of the motor.

Third, the fine selection of specifications and parameters

1. Wire diameter selection: according to the specific needs of the motor and the capacity of the winding machine, a reasonable choice of enameled wire diameter. Thicker wire diameter can withstand greater current, but may increase the difficulty of winding and occupy space; finer wire diameter is easier to wind, but need to consider its current-carrying capacity.

2. Insulation thickness: the thickness of the insulation layer should be moderate, not only to ensure good insulation properties, but also to avoid over-thickness caused by the increase in wire diameter and cost. According to the motor voltage level and working environment to determine the insulation thickness.

Fourth, applicability and economic trade-offs between the synthesis

1. Applicability: ensure that the selected enameled wire can adapt to the working environment of the motor, such as temperature, humidity, corrosive gases. In a special environment, need to choose the enameled wire with corresponding protective properties.

2. Economy: Under the premise of ensuring performance, consider the cost of enameled wire. By comparing different brands and models of enameled wire, choose cost-effective products to reduce the manufacturing cost of the motor.

V. Rigorous control in actual operation

1. Winding process: When winding coils, the operation should be carried out in strict accordance with the requirements of the process to ensure that the coils are neatly arranged and tightly without crossing. This helps to improve the electromagnetic performance and heat dissipation of the motor.

2. Quality Inspection: Strict quality inspection is carried out on the enameled wire in storage to ensure that it meets the specifications. At the same time, sampling inspection should also be carried out during the winding process to detect and deal with quality problems in time.

In summary, the selection of enameled wire for brushless motor winding machine is a complex and detailed work. Only by comprehensively considering the type of motor, power requirements, enameled wire material and performance, specifications and parameters, as well as applicability and economy, etc., can we ensure that the selected enameled wire meets the performance requirements of the motor and has good economy.
