Low-speed direct-drive three-phase permanent magnet synchronous motors
The concept of “direct drive” (also known as torque servomotor due to its large output torque) is based on the process of directly driving a load at low speeds without the need for a complicated mechanical transmission to reduce or increase torque.
Safe and reliable operation, simple structure, maintenance-free, to overcome the asynchronous motor and reducer transmission system of oil leakage and other problems.
- Directly drive the load, eliminating intermediate transmission equipment and improving transmission efficiency;
- High efficiency and energy saving, permanent magnet synchronous motor has a wider working range of high efficiency than ordinary asynchronous motor (i.e. induction motor), and the energy saving effect is obvious;
- Good torque performance, low vibration, low noise, low temperature rise, which can improve the working environment;
- Customized products with different speeds and torques are available according to customers’ requirements.
Product Description
Permanent magnet direct-drive motors cancel the reducer, hydraulic coupling directly drive all kinds of industrial machinery, compared with the traditional drive system, has a simple structure, reliable operation, low maintenance, small size, low loss, high efficiency, high power factor, high starting torque, drive intelligence, shape and size can be flexible and diverse and other significant advantages. At present, it is widely used in hydrometallurgy, new energy, biopharmaceutical, food and beverage industries.
1. Direct drive
Between the motor and the driven workpiece, it directly adopts rigid connection, without intermediate links such as screw, gear, reducer, etc., which minimizes the problems of backlash, inertia, friction and lack of rigidity existing in the transmission screw drive system.
2. High precision
Due to the adoption of direct drive technology, it greatly reduces the error brought by the intermediate mechanical transmission system, improves the system precision, and meets the occasions with strict requirements for precision machining accuracy.
3. Larger Motor Capacity Faster Response Speed
Direct drive motor can cover a larger power and torque range under the premise of low speed, providing larger motor capacity and faster response speed.
4. Low noise, simple structure, low maintenance cost
Direct-drive motors can cover a larger power and torque range at low speeds, providing greater motor capacity and faster response speeds.
5. Reduced intermediate transmission energy loss, higher mechanical efficiency.
