Product Description:

The MSK101E-0300-NN-M2-BG2-RNNN is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat as part of the MSK IndraDyn S Synchronous Motors series. It converts drive current from an electronic inverter into controlled torque and motion, allowing automated machinery to execute accurate positioning and velocity profiles in packaging, machining, and material-handling stations. When paired with a compatible drive controller, the motor supports closed-loop operation that helps maintain stable motion during changing load conditions.

This motor carries the cooling classification FN, meaning it relies on natural convection and can dissipate heat without an auxiliary fan or coolant circuit. Its rotor and stator are machined for increased concentricity to keep runout minimal at high speed. Position feedback is supplied by an optical encoder that delivers multi-turn absolute data through the EnDat2.1 digital interface. The measuring disk provides 2048 signal periods per revolution, enabling fine interpolation in the drive controller. An electrically released holding brake is integrated, and it can clamp the shaft with 70 Nm of static torque so vertical loads stay secure when power is removed. The housing meets the IP65 ingress rating to seal out dust and low-pressure water jets on the production floor.

The motor has size 101 and length code E, while winding code 0300 aligns the electrical constants with the MSK drive family. The drive end uses a plain shaft that mates with couplings or pulleys without keys. Power leads attach on the B-side to simplify cable routing in tight cabinets. Continuous operation is permitted in ambient conditions from 0–40 °C, and the insulation system is rated to class 155 so winding temperatures can rise without shortening varnish life. These operating characteristics suit equipment that requires compact servo performance with integrated feedback and holding capability.
