Permanent magnet synchronous motors have the advantages of simple structure, small size, high efficiency, and high power factor. Permanent magnet synchronous motors have achieved performance in medium and low voltage motors in industries such as metallurgy (ironworks and sintering plants), ceramics (ball mills), rubber (internal mixers), petroleum (pumping machines), and textile (double twisting machines, spinning machines), and gradually accumulated design and operation experience.
In the textile industry, the load has a large moment of inertia and requires high traction torque motors. Starting from the characteristics of the textile industry, the company reasonably designs the no-load magnetic leakage coefficient, saliency ratio, rotor resistance, permanent magnet size, and stator winding turns of permanent magnet variable frequency motors, thereby improving the traction performance of permanent magnet motors and making them more suitable for the new textile industry, adding another efficient and energy-saving motor product to the textile industry.
Structure and characteristics
Permanent magnet synchronous motors for textiles have the following advantages:
1. Stable performance, energy conservation and emission reduction, good synchronization, simple structure and easy installation;
2. Cancel excitation system losses and improve efficiency;
3. Cancel the excitation winding and excitation power supply to ensure reliable operation;
4. Rare earth permanent magnet motors have a compact structure, small size, light weight, and flexible and diverse sizes and shapes.
Main applications
Used in conjunction with equipment in the textile industry (double twisting machines, spinning machines).
