Product Description:

The MSK100A-0450-NN-S2-BG0-RNNN servo motor is manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. As a compact rotary actuator, it converts drive signals from IndraDrive controllers into mechanical torque for positioning, feed, and auxiliary axes in automated cells and machine tools. Its design follows the series emphasis on high torque density and encoder-integrated feedback, enabling precise closed-loop motion control in industrial automation lines. The motor is well suited to applications that require repeatable motion and a compact installation footprint.

Thermal dissipation relies on natural convection, so the frame disperses heat to ambient air without auxiliary fans or liquid lines. Motor size code 100 and length code A give the unit a medium-power envelope that fits standard MSK mounting dimensions. The motor uses a plain shaft and is built with increased concentricity, which helps reduce radial runout during coupling. Position feedback is generated by an optical single-chip sensor that provides 2048 signal periods per revolution, and this data is exchanged through the EnDat2.1 bidirectional interface for real-time position and diagnostic transmission to the drive.

Cable management is simplified because the power plug is on the B-side, allowing motor, encoder, and auxiliary conduits to run parallel along one face of the housing. The motor is supplied without a holding brake, so any axis that must remain fixed at standstill needs holding torque from the drive or an external mechanical restraint. Because the brake is omitted, the rotor can coast freely after drive shutdown unless the machine provides separate holding force. Electrical behavior is set by winding code 0450, which matches the voltage constant, current demand, and torque behavior expected by the IndraDrive amplifier.
