LOHER DYNAVERT L PWM Inverters for Lifts

Technical data overview Rated input voltage Typ. Safe, lohwr and disturbance-free operation using the integrated filter, reactors and contactor s for the travel commands.

Line supply cos phi 1: Low Voltage Converters go. Today, elevator drives are designed either as gearless or as geared solutions.

Loher Dynavert Drive System

They can control both synchronous as well as induction motors. The power flows from the line dnyavert to the motor for a motoring load.

They have a fully controlled B6 bridge circuit on the line side and a B6 inverter circuit on the output side, which utilizes the principle of interphase commutation; this distributes the DC link current from the DC dynavret reactors with a square waveform with frequency f to the motor winding.
