Product Description:

The MSK050B-0300-NN-M1-UG1-NSNN is an IndraDyn S synchronous servo motor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. The unit acts as the electromechanical drive element in automated cells, converting drive amplifier current into controlled torque and speed for material handling, packaging, and assembly lines. Its compact size 050 stator and length code B allow installation on axes where space and weight are limited, while continuous-duty accuracy remains important to consistent process performance.

The motor relies on natural convection for heat removal, so heat leaves the housing without auxiliary blowers or liquid loops. Its enclosure has an IP65 rating that prevents dust ingress and protects against water jets during washdown maintenance. Position feedback is transmitted through the Hiperface serial interface, enabling reliable data exchange with the drive. An electrically released holding brake provides 6 Nm of torque to keep vertical loads stationary when power is removed. Continuous operation is supported within an ambient temperature range of 0 to 40 °C, which suits standard industrial indoor conditions.

High-resolution optical sensing divides one mechanical revolution into 128 signal periods, and the multiturn absolute design retains position information over 4096 turns, which helps avoid homing after power cycles. The rotor end uses a plain shaft, allowing backlash-free clamp collars or couplings to be fitted without keyways. A Class 155 insulation system resists thermal aging during rapid acceleration duty, while winding code 0300 aligns the electrical characteristics with compatible IndraDrive controllers. The rotatable 240° encoder connector eases cable routing, and the standard build also meets explosion-protection requirements for use in designated hazardous zones.
