Servo Motors

The Quantum (QB) series is offered in both frameless and standard NEMA housed versions. The frameless models are designed for direct integration with the driven shaft or gearbox. The housed NEMA models can be equipped with an encoder or resolver for feedback. Custom versions of the Quantum series to exactly match application requirements are easily developed from our standard platform designs.
