ESR Pollmeier GmbH - Servo Drive Technology

Servo Motors and Gear Boxes

With a torque range of 0.1 to 70 Nm, servo motors by ESR cover a wide spectrum of typical servo applications. The AC servo motors of the MR series impress by their high power density and high torques within compact dimensions; they are suited for universal use. The scope of delivery is rounded off by DC servo motors for lower powers.
