Wound rotor type motors are a common type of electric motor whose design and construction make them suitable for a variety of applications, including industrial production, household appliances, and automotive engineering. Known for their simplicity, reliability, and efficiency, this type of motor usually consists of windings, magnets, and a rotating shaft.
The core component of a wound motor is the winding, which is made of insulated coils and installed on the iron core of the motor. These coils are usually made of conductive materials, such as copper or aluminum wires. When current is passed through these coils, they generate rotational torque in the magnetic field to drive the rotation of the motor.
Wound rotor type motors also include magnets, usually permanent magnets or electromagnets, that are used to generate the motor's magnetic field. This magnetic field interacts with the current in the windings to produce the force and torque required by the motor to operate the motor. The rotating shaft of the motor is connected to the load or transmission system to convert the rotational force generated by the motor into actual mechanical motion to complete the required work.

In the manufacturing process of the wound rotor motor, ensuring the accurate number of turns of the electromagnetic wire and even force is crucial to improving the performance and service life of the motor. Shanghai Pinxing Motor, as a leading company dedicated to global industrial motor technology solutions, has integrated advanced management and technical means in the winding process to ensure the high precision and high reliability of this key step.
Accurate control of the number of turns
Automated winding equipment: Pinxing Motor uses a high-precision automated winding machine to wind the electromagnetic wire. The equipment has a built-in precise counting system that can accurately control the winding of each turn, effectively avoiding errors caused by manual operation, and ensuring the accuracy of the number of turns.
Intelligent programming: Combined with information management systems such as ERP and PLM, Pinxing Motor accurately programs the winding parameters of each motor, including the number of turns, wire diameter, winding speed, etc., to achieve data traceability and adjustability, and further optimize production efficiency and product quality.
Uniform force control
Tension control system: The automated winding equipment is equipped with an advanced tension control system that can monitor and adjust the tension of the electromagnetic wire in real time during the winding process to ensure that the electromagnetic wire is uniformly stressed, avoiding the phenomenon of thinning or breaking due to excessive tension, and also avoiding the problem of loose winding due to insufficient tension.
Material selection and pretreatment: Pinxing Motor strictly selects high-quality electromagnetic wire materials, such as high-quality copper wire or aluminum wire, and performs necessary pretreatment, such as annealing, to improve the flexibility and tensile strength of the electromagnetic wire, thereby further ensuring the uniformity of force during the winding process.
Quality inspection and feedback: After the winding is completed, Pinxing Motor implements a strict quality inspection process, including turn review, appearance inspection and performance testing, to ensure that each motor meets high standards. At the same time, customer feedback is collected through the CRM system to continuously optimize the winding process to meet the special needs of different application scenarios.
With its advanced automated winding equipment, intelligent management system and strict quality control process, Shanghai Pinxing Motor ensures the accuracy of the number of electromagnetic wire turns and the uniformity of force during the winding process of wound rotor motors, thereby providing customers with more reliable and efficient motor products.
After the winding of the wound rotor motor is completed, how to effectively insulate the windings to prevent electrical faults and short circuits?
After completing the winding process of a wound rotor motor, effective insulation treatment of the windings is a crucial step, which is directly related to the electrical performance, safety and long-term operation reliability of the motor. Shanghai Pinxing Motor, as a leader in the motor industry, has demonstrated significant advantages in winding insulation treatment with its advanced production technology and strict quality management system. The following are the key steps to insulate the windings of wound rotor motors based on the company's advantages:
High-quality insulation material selection: Shanghai Pinxing Motor uses high-quality insulation materials that comply with international standards, such as high-performance insulating paint, insulating paper, and insulating sleeves. These materials have good heat resistance, chemical resistance and mechanical strength, ensuring that the windings can maintain stable insulation performance under different working conditions.
Precision winding and solidification process: During the winding process, Pinxing Motor uses precise winding equipment and technology to ensure that the coils are arranged neatly and tightly, and to reduce gaps and looseness. After the winding is completed, advanced curing processes, such as vacuum dipping and high-temperature drying, allow the insulating material to fully penetrate into every detail of the winding, forming a strong insulating layer to effectively prevent electrical failures and short circuits.
Quality control under information management: Pinxing Motor uses information management systems such as ERP and MES to accurately control and record every step in the insulation treatment process. From material warehousing and use to quality inspection during the production process and finished product delivery, traceability is achieved in every step to ensure that the quality of the insulation treatment meets the highest standards.
Strict inspection and testing: After completing the insulation treatment, Pinxing Motor will also conduct strict electrical performance testing and insulation strength testing on the windings. Through high-voltage testing, insulation resistance measurement and other means, we ensure that the windings can still maintain good insulation performance under extreme conditions such as high voltage and high temperature to prevent the occurrence of electrical faults.
Continuous technological innovation: As a leader in motor technology, Shanghai Pinxing Motor continues to invest in research and development to explore new insulation materials and processes. Through technological innovation, we continuously improve the insulation performance of the windings and the overall performance of the motor to meet the market's demand for energy-saving, efficient, and environmentally friendly motors.
Shanghai Pinxing Motor ensures the effective winding of wound rotor motors by selecting high-quality insulation materials, adopting precision winding and curing processes, implementing quality control under information management, strict inspection and testing, and continuous technological innovation. And reliable insulation treatment to prevent electrical faults and short circuits, providing customers with safer, more reliable and efficient motor products.
