Product Description:

The MSK101E-0300-NN-S3-BG2-NNNN servo motor is built by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. Classified as an IndraDyn S synchronous servo motor, it converts electrical command signals into controlled rotational motion for automated handling, packaging, and machining axes. The unit combines power and feedback in a single-cable layout, which reduces external wiring and helps keep machine layouts compact. Its internal encoder lets a compatible drive controller manage position and speed without a separate external transducer, which supports accurate closed-loop motion on multi-axis equipment.

The motor uses natural convection for cooling, eliminating the need for forced air or liquid circuits while dissipating winding losses during normal operation. Position data are supplied through a Hiperface interface; within the encoder, a capacitive measuring system delivers 16 signal periods per electrical revolution in a single-turn profile, supporting accurate commutation and fine speed control. An electrically released holding brake provides 70 Nm of static torque to secure vertical or suspended loads when power is removed. The housing has an IP65 rating, which helps protect internal components from dust and low-pressure water exposure on the factory floor.

The motor uses a plain shaft, so torque is typically transferred through backlash-free couplings rather than a keyed connection. Winding code 0300 is used in a size-101 stator with extended E length, giving the motor the electromagnetic layout assigned to this frame. All electrical terminations exit on the B-side power connector, which can simplify cable routing where adjacent axes leave limited clearance near the drive end. Operation is permitted in ambient temperatures of 0–40 °C, and insulation class 155 supports the thermal endurance expected during continuous-duty service.
