In view of the high energy consumption, complex structure, and high maintenance cost of traditional metal drawing equipment in the cable industry, the use of a low-speed and large-torque permanent magnet direct drive motor will effectively solve the problem. The power structure design and process of low-speed high-torque permanent magnet motor improve the transmission efficiency and service life of the wire drawing machine, solve the inherent loss of wire drawing during the working process of the traditional wire drawing machine, and save the motor installation space and effectively improve motor efficiency.
The direct-drive permanent magnet synchronous motor for wire drawing machine has the advantages of high efficiency, energy saving, environmental protection, low noise, maintenance-free, etc., and has good performance goals. Compared with traditional wire drawing machines, energy consumption is reduced by 15%-20%. In the traditional asynchronous variable frequency speed regulating motor, when working under 60% load, its power is reduced by 15%, the power factor is reduced by 30%, and the energy target is reduced by 40%. The efficiency and power of the permanent magnet synchronous direct-drive motor are similar to a horizontal curve. Even when the motor has only 20% load, the force energy target of the permanent magnet synchronous servo motor is still more than 80% of the full load, thus increasing the power and power of the electric energy.
Design features of permanent magnet direct drive motor:
1. The design of high-temperature-resistant multi-pole rare earth magnets has good control dynamic performance;
2. Support industry customized motors, and can design standard non-standard speed high-efficiency permanent magnet motors such as 20Rpm~3000Rpm/Min;
3. Small torque fluctuation accuracy, silent design, high dynamic response speed, use vector controller for application control;
4. Support step-less speed regulation and operation in various speed conditions.
5. It can replace the traditional belt transmission method, remove complex transmission structures such as belts, pulleys, and reducers, optimize power output and reduce torque loss;
6. With a large inertia design, it can easily adapt to low-speed operation, high-torque start-up and heavy-load requirements, and high-speed operation with a small current;
7. Support jog and slow-motion functions to meet a variety of working conditions;
