Schindler Variodyn VF44BR

The most robust drive in the Schindler Variodyn range the VF44BR is a regenerative drive for use with MRL motors which require close control at very low speeds in order to maximise passenger comfort.

With international distributors NDC Elevator Drives provide a high quality repair service for both the Variodyn drive and the associated MRL motor worldwide. This gives you a single point of contact for all your MRL elevator motor and variable frequency drive repair requirements.

Highly efficient the VF44BR has the capability to recoup the energy created by the elevator carriage during descent and feed this back into the supply offsetting energy used and, thereby reducing the carbon footprint of the elevator.

As with the other Variodyn drives the Variodyn VF44BR can be mounted inside the shaft with the MRL elevator motor eliminating the need for separate machine rooms, saving on the space required for the elevator system and on the ongoing running costs.

This highly complex regen VF44BR drive therefore requires high speed communication protocols to process system information quickly, not only monitoring the drive performance but also the real time feedback from the MRL motor encoder.

Using the Miconic processor the Schindler Variodyn system is one of the most complex elevator drive systems and NDC Elevator Drives has committed many years of research and development to developing test rigs capable of running the drive system in order to prove repairs 100% under real word operating conditions.

This approach to developing and maintaining quality and guaranteeing the reliability of our repairs has made NDC Elevator Drives a global leader in the supply, repair and service exchange of Schindler Variodyn elevator drives.
