AC servo-motor

With a torque range of 0.1 to 70 Nm, serovo motors by ESR cover a wide spectrum of typical servo applications. Standard AC servo motors MR 4 and MR 6 are intended for universal use. Additionally there are the MR 7 motor series with particular high power density; they are mainly used when high torques are needed within compact dimensions. The scope of delivery is rounded off by DC servo motors RS/RX/AXEM for lower powers.

Characteristics of the AC servo motors
- maintenance-free, since brushless
- high dynamics
- wide speed control range
- high power density through rotor with rare earth magnets
- compact servo motors with particular high power density due to improved winding techniques (MR 74, MR 77) or standard servo motors for universal use (MR 4, MR 6)
- ball bearings suppliers with grease filling for 20,000 operating hours
- integrated resolver for sinusoidal commutation, optional optical encoders (incremental or absolute, single- or multiturn) for highest dynamics and accuracy
- insulation according to insulation class F, DIN VDE 0530, withstanding tropical conditions
- easy connection of motor and professional encoder using connectors supplier or terminal cases
- self-cooling, on request cooling through external professional fan motor
- design with flange according to DIN 42 677, installation position as required
- form according to DIN IEC 34 part 7, IM B 5
- bearing suppliers plates and housings made of high-quality light metal alloy
- speed of up to 15,000 r.p.m. possible
- rotor dynamically balanced according to vibration severity grade R, on request S
- standard shaft end without groove, special version possible, e. g. with keyway
