MRL Motors: An Overview

For lift companies to support these motors, having a repair partner that has the correct in-house technology and know-how is crucial.

At NDC, we understand the shift in the complexity of elevator technology and the expectations this places on companies operating in the repairs market.

For MRL applications, the electronic drive and the motor can be a ‘matched pair’. Therefore, having the capability to refurbish both is important to guarantee safety standards, reliability and a fast turnaround. NDC’s elevator drives business, and ServoLab facilities ensure that we can offer a credible alternative to the motor OEM’s themselves.
