Permanent Magnet Direct Drive Motor

2021-11-02

Direct drive motor mainly means that the motor does not need to pass through the transmission device (such as transmission belt, etc.) when driving the load. 

1. Traditional motors are generally 1500rpm and 3000RPM, which cannot achieve low-speed or high-speed operation. In many cases, a reducer or speed-increasing machine must be installed in the motor and driven equipment to achieve the low-speed, high-torque, or high-speed operation required by the equipment. The transmission link is increased, the system efficiency is reduced, and energy is wasted.

2. The use of permanent magnet direct drive motors can eliminate the need for speed changers or mechanical reversing mechanisms to achieve direct drive of the equipment. High efficiency and energy-saving, saving 30~60% of electricity consumption compared with the existing transmission method, and the cost can be recovered through energy saving.

3. Good torque performance, large low-speed torque, small low-speed vibration, small motor starting current and running current, and strong overload capacity.

4. The system has a small moment of inertia, good dynamic response, and improves transmission quality.

5. Avoid the trouble of oil leakage and noise of the gearbox and reduce the amount of maintenance.

6. A variety of motor operation modes, such as continuous work, interval work, variable speed work, forward and reverse operation, fixed-point positioning, fast braking, soft start, and soft stop, etc. can be used according to the needs of the equipment.

7. The number of poles of the low-speed motor is large. According to different requirements, the number of poles of the motor is designed to be between 12 poles and 64 poles.

8. Multiple protection functions, multiple display functions, multiple communication functions.

9. A variety of motor shapes can be made into horizontal, vertical, double shaft extension, hollow shaft, and spline shaft extension.

10. The driver can be put into the box, and the box can install and protect the driver and can adapt to different environments. The box contains circuit breaker meters, indicator lights, buttons, wiring terminals, etc.
