Low-speed permanent magnet direct drive synchronous motors can provide high torque at low speeds directly on the driven machine. Due to the permanent magnet rotor, high efficiency and high power factor can also be achieved at low speeds.
The low-speed permanent magnet direct drive synchronous motor is provided as a coordinated system together with the variable frequency drive cabinet, forming a long service life drive solution with low life cycle cost and high efficiency in low operating speed applications.
Client benefits:
1. For low-speed drives, the efficiency of high-power torque motors is 2-3% higher than similar drives;
2. The multi-pole motor design ensures that these motors are space-saving and lightweight compared to similar asynchronous motors, and high-power torque motors do not require the use of reducers in many cases, reducing configuration, assembly, and maintenance costs, as well as investment and operation cost.
3. Environmentally friendly system (no need to deal with gearbox oil when applicable: energy-efficient drive system).
4. The frequency converter and the high-power torque motor form an optimally matched high-efficiency system, and there is no need to use an encoder during operation.
5. The high-power torque motor has a long operating life (nominal bearing life > 60,000 hours), is maintenance-free, and has high availability, especially for applications where the reducer can be omitted.
6. Customization
Typical application:
Applications with high requirements in terms of drive solutions with high efficiency, low space requirements, and low life cycle costs. The main application areas are as follows:
1. Roller and press drives in the paper industry
2. Propeller drives (main drive and auxiliary drive) in the shipbuilding industry
3. Worm drives, servo press drives, and shearing machine drives in the steel industry
4. Extruder screw drive and pull mill drive in the plastics industry
5. Wide application in the crane industry
6. Sugar centrifuges in the sugar industry
