1. What is an Electric Motor Winding Machine?
The electric motor winding machine is an automated device specially used to manufacture motor coils. It winds the enameled wire or other wires around the iron core in a specific way through precise control to form the heart of the motor: the coil. This coil is a key component for the motor to generate a magnetic field and determines the performance parameters of the motor.
The motor is like a heart, and the coil is its blood vessel. The winding method, number of turns, and material of the coil directly affect the power, speed, efficiency, etc. of the motor. The bldc motor winding machine is like a skilled weaver. It weaves threads of various colors into exquisite cloth according to specific patterns based on different motor design drawings.
The electric motor winding equipment is an indispensable equipment in the motor manufacturing process. It winds the wire into coils in a specific way through precise control and automated operation, thereby manufacturing various types of motors. With the development of the motor industry, the automatic motor winding machine will also continue to innovate and provide stronger support for the development of the motor manufacturing industry.
2. What are the Classification and Characteristics of Motor Winding Machine?
There are many types of motor winding equipment, and their classification and characteristics are mainly divided according to the degree of automation, winding method, product type, etc.
According to the degree of automation:
-
Manual winding machine: simple structure, flexible operation. Low production efficiency and low precision are mainly used for small batch, customized coil production. The high proportion of manual operation is easily affected by human factors.
-
Semi-automatic winding machine: some processes are automated, such as wire feeding and wire cutting. The production efficiency is higher than that of manual winding machine, but the accuracy still needs to be improved. Suitable for small and medium-sized batch production.
-
Fully automatic winding machine: The entire winding process is automated, including wire feeding, wire cutting, wire winding, forming, etc. High production efficiency, high precision, stable product quality. Suitable for mass production.
According to the winding method:
Needle winding machine: insert the wire into the core slot through the needle bar, and then rotate the core to realize the winding of the wire. It has the characteristics of high degree of automation, high precision, wide application range, and can use a variety of complex winding processes. Needle winding machine is widely used in the winding of various motor stator coils, especially suitable for small batch and multi-variety customized production.
Flat winding machine: The wire is laid flat on the iron core, and then the winding is achieved by moving the wire rack and the iron core. It has the characteristics of simple structure, easy maintenance, simple operation, and lower cost compared to other winding machines. Flat winding machines are mainly used to wind simple coils, such as single-layer coils, cylindrical coils, etc.
Flying fork winding machine: The wire is clamped by the flying fork, and then the wire is inserted into the core slot to achieve winding. It has the characteristics of fast winding speed, high production efficiency, wide application range and high degree of automation. Flying fork winding machine is widely used in large-scale and high-efficiency motor stator coil winding, especially for the production of high-performance motors such as automotive motors and servo motors.

3. Motor Winding Machine Selection Guide
-
Determine the type of motor to be produced (such as brushless motors, brushed motors, stepper motors, etc.). Different types of motors have different requirements for winding machines. Choose a suitable winding machine according to the production scale. Small batch production can choose manual or semi-automatic winding machines, and large batch production requires fully automatic winding machines. For high-precision motors, such as automotive brushless motors, you need to choose a high-precision winding machine. Different winding processes also have different configuration requirements for winding machines, such as single-layer winding, multi-layer winding, staggered winding, etc.
-
Pay attention to key performance indicators. The higher the degree of automation, the higher the production efficiency, but the higher the cost. Winding accuracy directly affects motor performance. Choosing a winding machine with high accuracy can improve motor quality. Whether the winding machine can adapt to a variety of motor models, the stronger the adaptability, the higher the flexibility. The stability of the winding machine directly affects production efficiency. Choosing equipment with high reliability can reduce downtime.
-
Compare the technical parameters of winding machines of different brands and models, such as winding speed, wire diameter range, and tension control accuracy. Compare standard configurations and optional configurations, such as servo motors, tension control systems, and automatic mold change devices. Understand the supplier's after-sales service policy, including warranty period, repair services, spare parts supply, etc.
-
Visit the motor winding machine manufacturer factory and conduct on-site inspections. Visit the factory in person to understand the production process and equipment performance. If conditions permit, you can try out the machine to understand the operating interface, ease of use, etc.
-
Consider the cost of the equipment: Compare the prices of equipment of different brands and models and choose the product with the best cost performance. In addition to the purchase cost of the equipment, the operating cost, such as power consumption and maintenance costs, should also be considered.
-
Get professional advice: You can consult motor manufacturing industry experts or experienced engineers to get professional advice. Refer to relevant industry standards and choose a winding machine that meets the standards.
