Schindler Variodyn VF11BR

The Schindler Variodyn VF11 is a custom designed inverter for controlling a permanent magnet motor at very low speeds. NDC Elevator Drives provide repair for both the Variodyn drive and the associated MRL motor, giving you a single point of contact for all your major engineered elevator components.

Most often used in flagship MRL elevator applications and ‘feature’ lifts the Schindler Variodyn drive can be mounted inside the shaft with the motor eliminating the need for a separate machine room to provide drive and control for the elevator, a concept pioneered by Kone with the V3F range of drives.

As a gearless MRL system the motor must be tightly controlled when operating at low speeds to avoid any passenger discomfort.

The Schindler Variodyn MRL drive system therefore relies upon a number of high speed communication protocols to move the information around the system quickly. Not only monitoring the drive performance but also the real time status of the motors own encoder via a serial link.

Running in conjunction with the latest series of Miconic processor the Variodyn system is by far one of the most complex elevator drive systems to test outside the elevator and has taken NDC Elevator Drives many years of research and development to complete a suite of simulators capable of running the drive system in order to prove repairs 100% under simulated real word operating conditions.

This dedication to quality and reliability has made NDC Elevator Drives a global leader in the supply and repair of elevator drives.

The Schindler Variodyn VF11BR is the 11amp version of the Variodyn range which is available in a variety of capacities from 8amp through to 42amp for differing applications.
