Product Description:

The MSK103D-0300-NN-M2-UG0-RNNN is a synchronous servomotor built by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. As an IndraDyn S synchronous servomotor, it delivers closed-loop torque and position control to automated axes in machinery such as packaging lines, gantry systems, and process equipment. The motor integrates with compatible drive controllers to convert commanded current into precise rotary motion for indexing, feed, and positioning tasks. Its compact construction supports installation where machine space is limited but accurate response and repeatable motion are still required.

Cooling relies on natural convection, so heat is removed through the housing without external fans. The motor uses frame size 103 with D length code and winding code 0300 for its intended torque range, and its design reduces radial runout at the shaft for smoother mechanical operation. Feedback is provided by an optical encoder that communicates through the EnDat2.1 interface, and its connector is rotatable 240° to help route the feedback cable in tight mounting spaces. The encoder delivers 2048 signal periods per revolution, allowing the drive to interpolate fine position values for precise motion control. A plain shaft transmits torque directly to couplings or gearboxes and suits applications that do not require a keyed shaft connection.

The motor is supplied without a holding brake, so standstill holding must be provided by drive torque or an external clamping device when required. Its housing carries an IP65 rating that protects against dust ingress and low-pressure water jets in industrial environments. Continuous operation is allowed within an ambient range of 0–40°C, which supports typical indoor machine conditions. The Class 155 insulation system supports winding temperatures associated with cyclic duty and helps the motor tolerate repeated load changes during operation.
