Product Description:

The MSK101C-0300-NN-M1-BG2-NNNN is a synchronous servomotor built by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It converts electrical power from a compatible drive into precise rotary motion and torque, permitting closed-loop speed, position, and acceleration control in automated packaging, assembly, and machining stations. The C-length, size-101 frame provides the mechanical interface needed for high-moment inertia loads, while the B-side power connector simplifies routing inside multi-axis cabinets. This motor is suitable for axes that need repeatable movement during frequent starts, stops, and directional changes.

Heat generated during operation is dissipated by natural convection, so the motor does not require an external blower. Position feedback travels through the Hiperface serial channel, allowing electronic nameplate recognition and real-time data exchange with the controller. The motor’s optical encoder delivers 128 signal periods per mechanical revolution, providing fine incremental resolution for velocity control. Because the encoder is a multiturn absolute device, shaft location across up to 4096 revolutions is retained after power removal. An electrically released brake supplies 70 Nm of static torque to hold the axis when the drive is disabled. This feedback and brake arrangement supports controlled restarting and secure standstill behavior on vertical or suspended loads.

The enclosure carries an IP65 rating that seals internal components against dust and low-pressure water jets, allowing direct machine-frame mounting. A plain shaft output reduces backlash when clamp collars or shrink disks are used, and it suits direct coupling arrangements that favor low play in the drivetrain. Continuous duty is permitted in environments from 0 to 40 °C, provided ambient air can move across the ribbed housing for cooling. Class 155 insulation withstands elevated winding temperatures generated by the 0300 winding code during peak cyclic loads. This thermal class helps the winding system tolerate repeated load changes in demanding automation service.
