Turn off more accessible mode. Today, elevator drives are designed either as gearless or as geared solutions. Customer benefits Cabinet units in IP21 or higher degrees of protection All of the drive units have their own connection space Compact dimensions Equipped with radio interference suppression Low harmonics fed back into the line supply, mainly on and louer versions Almost unlimited motor cable lengths possible inherent to the system High overvoltage strength, e.

Output voltage basic fundamental: As a consequence, the motor cable length is almost unlimited. Low Voltage Converters go. This is the reason that no additional wiring is required. Two closed-loop control types for induction motors: This means that from the inherent principle, 4-quadrant operation is possible without requiring any additional measures. Depends on the motor Line supply frequency: Medium Voltage Converters go. IP21, higher degrees of protection optionally available.

Loher Dynavert Drive System

Low Voltage Converters go. Up to an elevator power of 30 kW the drive unit can be dynvaert in a control cabinet with a depth of mm. Selection and Engineering Tools go. For regenerative operation, the rectifier on the line-side feeds the regenerated energy back into the line supply. They can control both synchronous as well as induction motors.

Customer benefits Compact and ready-to-connect unit with integrated EMC filter, line reactor, braking chopper, braking resistor and a quiet contactor for the travel commands. 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 link reactors with a square waveform with frequency f to the motor winding.
