VVVF - Smoothly motor speed control

Elevator motor speed control by VVVF

VVVF (Variable Voltage Variable Frequency) – Inverter to regulates input voltage and frequency when elevator is moving. With VVVF elevator will draw less current when accelerating or decelerating, reduce energy consumption, leads to superior ride quality and accurate floor leveling.

ZIEHL-ABEGG ZAdyn series are frequency inverters developed exclusively for elevator technology. The varied housing designs and universally compact construction make them ideal for either switch cabinet installation or wall mounting in the machine room or elevator shaft.

Applications:

> Cable elevators with asynchronous or synchronous motors;

> Speed up to 6.5 m/s;

> Nominal current of 11 A – 180 A;

> Nominal output of 4.6 kW – 90 kW
