Rexroth MSK061C Servo Motor

Rexroth MSK061C precision industrial motor
MSK061C IndraDyn S compact high-torque motor
Bosch Rexroth MSK061C high-performance servo motor

Description:

The Rexroth MSK061C is a high‑performance synchronous servomotor from the MSK (IndraDyn S) series — engineered for precision motion control, automation, CNC, robotics, and industrial applications. Compact in size yet capable of delivering up to 32 Nm peak torque, it balances robust power output with a compact frame. With its optical absolute encoder (Hiperface interface), IP65 protection, and natural or surface cooling options, the MSK061C offers reliability, accuracy, and durability for demanding drive and control systems.
