Escalator Supplier introduced that an elevator inverter is a kind of instrument specially used for elevator control.
The elevator-specific inverter is a high-end product among medium and small power inverters. It improves elevator efficiency, runs smoothly, and prolongs equipment life. Combined with PLC or microcomputer control, it shows the advantages of non-contact control: simplified wiring, flexible control, and improved operation. Reliability, easy maintenance, and fault monitoring. The frequency converter is very common equipment in modern electrical equipment, and the elevator frequency converter is an instrument specially used for elevator control. The control of the elevator inverter on the elevator is S-type, that is, the acceleration of starting and stopping is relatively gentle, and the acceleration is relatively fast in the middle process, mainly for the comfort of riding, and energy-saving is also on the one hand, which is the general advantage of the inverter. For the elevator to be comfortable, the elevator needs to accelerate slowly, which involves the problem of motor speed regulation:
1. Other speed regulation methods, such as series resistance speed regulation: reduces the voltage inside the motor and reduce the speed by connecting a resistor in series. The disadvantage is that a certain amount of energy is consumed on the series resistor;
2. There is no such situation with the inverter. It directly controls the output frequency and voltage to drive the motor, and there is no additional consumption.
