The car elevator uses a permanent magnet synchronous traction machine that is energy-saving, environmentally friendly, stable in operation, low in noise, and small in space. Next, the elevator sales editor will introduce to you.
Structural characteristics of car elevators:
1. The structure is simple, no reduction box is needed, the process is simpler, and the volume and weight are reduced, and the utilization rate of the effective space is improved.
2. Low vibration and low noise, especially in the low-speed working area, the advantages are more obvious, the work is stable, and the speed regulation accuracy is high. Geared traction elevator noise is mainly caused by the mechanical vibration and noise of the gearbox and the high-speed rotating motor itself. Since gearless traction does not require a reduction box, the rated speed of the motor is very low, so the vibration and noise of the motor itself are very small, thereby greatly reducing the noise of the entire elevator system.
3. The car elevator realizes gearless speed regulation and does not require the secondary deceleration process, which saves gearbox losses and improves efficiency. After using permanent magnets for excitation, there is no need for excitation current, no excitation loss, and the efficiency of the system can also be improved.
4. The power factor is too high. The energy coefficient can reach more than 0.9.
5. It is safe, reliable and comfortable; it is driven by a permanent magnet synchronous motor, which can effectively prevent the elevator from slipping. At the same time, the motor can also provide sufficient torque at low frequency, low pressure, and low speed to avoid the jitter of the elevator during the start-up retarding process, and improve the comfort of the elevator's braking process.
6. Machine-room-less elevators with various traction modes can be arranged, even if the machine room and small machine room are arranged, they can show a high degree of freedom and flexibility.
