The bad use of the hoist may be related to the selected permanent magnet motor!

The hoist is a large-scale mechanical equipment that transports by changing potential energy, such as mine hoist, dam passing hoist, etc. The elevator generally refers to the large-scale mechanical equipment with high power strong lifting capacity.

The motor is the power source of the hoist. If the motor is selected properly, the chain will be dropped when the hoist is working, so the permanent magnet motor plays a very important role in the hoist.

1. Using the low-speed high torque permanent magnet motor drive system, removing the external reducer, reducing the intermediate transmission link, greatly increasing the safety, reliability reliability. It can eliminate the leakage, reduce the pollution to the environment the consumption of spare parts.

2. Using the low-speed high torque permanent magnet motor drive system, since the rotor has no induced current, the rotor does generate heat, the heat dissipation is easier to solve, the temperature rise of the motor is low.

3. Small size, light weight high comprehensive cost performance. It is suitable for projects with limited foundation bearing installation space in new construction reconstruction projects.

4. Under the same working condition, using low-speed high torque permanent magnet motor drive system to drive the conveyor directly can reduce the power supply capacity purchase cost. The new equipment adopts the low-speed high torque permanent magnet motor drive system, which will greatly reduce the project cost reflect its energy saving efficiency.

5. It can operate at low speed during shutdown maintenance, because the auxiliary transmission system is cancelled, the complexity of equipment is further reduced, the working efficiency of the system is improved, the vibration noise are significantly reduced due to the low speed of the system,

The permanent magnet motor uses the permanent magnet to generate the magnetic field of the motor, without excitation coil excitation current. It has high efficiency simple structure. It is a good energy-saving motor. With the emergence of many good permanent magnet materials the rapid development of control technology, the application of permanent magnet motor will become more extensive.
