Product Description:

The MSK101D-0300-NN-M2-BG2-RNNN is a servo motor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. This motor acts as a rotary actuator that pairs with IndraDrive controllers to deliver precise torque and speed for automation axes such as gantries, packaging lines, and tooling spindles. By combining optical position feedback with an electrically released holding brake, the unit maintains axis position during power-off states while fitting into sealed machine compartments. That combination also supports controlled holding on vertical or suspended loads when motion stops unexpectedly. The enclosed design suits equipment where exposed moving parts and external cooling devices are undesirable.

Thermal handling is provided by natural convection, so the housing sheds heat without forced airflow and matches the Cooling FN arrangement used with the D-length frame. An optical encoder using the EnDat2.1 interface streams absolute position data, and its resolution of 2048 signal periods supports fine interpolation inside the drive for smooth velocity loops. The factory-mounted brake supplies 70 Nm of static torque so vertical axes stay locked when supply is removed, and it releases automatically when the coil is energized. Environmental sealing meets IP65, so dust ingress and low-pressure water jets do not affect the windings or feedback electronics. The 101 frame size, increased concentricity design, and 0300 winding code balance torque density with thermal rise during cyclic motion.

The position sensor uses a multi-turn absolute architecture, so stored turn information remains available after downtime and supports restart without a homing routine. Insulation class 155 supports elevated winding temperatures during continuous duty and matches the operating demands of this winding code. A plain shaft simplifies coupling to backlash-free clamping hubs, and the concentricity tolerance helps reduce radial runout during high-speed operation. The motor is intended for ambient conditions of 0–40 °C, which keeps the brake and encoder within their normal operating range. This layout is well suited to enclosed machinery that requires stable feedback and dependable holding behavior during repeated motion cycles.
