Product Description:
The MSK100C-0300-NN-M1-RP2-NNNN is an IndraDyn S synchronous servomotor built by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It converts drive current into controlled rotary motion for machine tools, packaging axes, and automated handling cells that require accurate positioning and repeatable speed control. The motor is intended for closed-loop operation with a matching drive so commanded torque changes can be translated into smooth shaft response during indexing, feeding, and transfer moves. An integrated electrically released holding brake helps keep the axis locked during standby or power-off intervals, which is useful on vertical or intermittently cycled stations. This makes the motor suitable for applications that alternate between rapid acceleration and precise dwell periods.
Mechanically, the unit uses natural convection cooling, so clearance around the housing is needed to support airflow across the ribbed frame. Because no auxiliary fan is required, the outer dimensions remain free of added cooling hardware. Its enclosure has an IP65 rating that helps keep dust and water jets away from the internal windings and feedback components. An electrically released holding brake provides 70 Nm of static torque for secure load retention when drive power is removed. The motor can operate in ambient temperatures from 0–40 °C under normal conditions, and a shaft with keyway supports positive torque transfer to couplings, pulleys, or similar driven elements.
The motor uses an optical encoder with a Hiperface interface for position data exchange with the drive. It provides 128 signal periods of base resolution, and its multiturn absolute capability allows position tracking across multiple mechanical revolutions without losing reference after shutdown. This feedback arrangement supports immediate position availability at startup and stable commutation through the operating range. The stator insulation system is rated for class 155 thermal limits, matching the thermal demands of the 0300 winding code. A right-side power connector helps keep cable routing compact in machines where space beside the motor is limited.
