The elevator is a large mechanical equipment that is transported by changing the potential energy, such as the mine elevator, the dam elevator, etc. Elevator generally refers to large power, strong lifting capacity of large mechanical equipment.

The motor as the power source of the elevator work, if the motor is selected properly, then the elevator will definitely lose the chain when working, so the permanent magnet motor plays a very important role in the elevator.

1. The use of low-speed high-torque permanent magnet motor drive system, remove the external reducer, reduce the intermediate transmission link, safety reliability greatly increased. Prevent leakage, reduce environmental pollution spare parts consumption.

2. The use of low-speed high-torque permanent magnet motor drive system, because the rotor does induce current, so the rotor does generate heat, heat dissipation is easier to solve, the motor temperature rise is low.

3. Small size, light weight, high comprehensive cost performance. It is suitable for new construction renovation projects that have limited foundation load installation space.

4. Under the same working conditions, the use of low-speed high-torque permanent magnet motor drive system to directly drive the conveyor can reduce the power supply capacity reduce the procurement 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 high efficiency.

5. It can run at a low speed when it is stopped for maintenance, because the auxiliary transmission system is cancelled, which further reduces the complexity of the equipment improves the working efficiency of the system. Moreover, due to the low speed of the system, the vibration noise are significantly reduced.

Permanent magnet motor uses permanent magnet to generate the magnetic field of the motor, no excitation coil nor excitation current, high efficiency simple structure, 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 motors will become more extensive.
