Product Description:
The MSK101D-0450-NN-M1-AG3-NNNN is a synchronous servo motor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It provides precise, closed-loop rotary actuation for automated pick-and-place modules, packaging lines, and machining centers where rapid acceleration and repeatable positioning are required. Used with IndraDrive amplifiers, the motor converts electrical energy into controllable torque while maintaining compact dimensions that fit easily into multi-axis gantries and tooling spindles. Its rigid stator housing supports direct mounting to the machine frame, reducing couplings, alignment steps, and routine maintenance.
Cooling by natural convection eliminates supplemental blowers, and a die-cast body sealed to IP65 blocks dust and low-pressure water jets that could otherwise reach internal components. An electrically released brake delivers 120 Nm of static torque so vertical axes stay secure when supply power is removed. Rotor position is monitored by an optical encoder that communicates through the Hiperface serial link and offers 128 signal periods per mechanical turn, supporting fine incremental control. Size code 101 with length code D increases active stator length for higher continuous output, and winding code 0450 matches the electrical characteristics to compatible IndraDrive current ratings. The power connector is located on the A-side, allowing cable routing parallel to machine profiles.
The Multiturn Absolute encoder variant records complete shaft revolution counts, eliminating homing routines after emergency stops. A cylindrical plain shaft simplifies coupling to timing belts or precision gearboxes and helps reduce torsional windup. Continuous operation is permitted between 0–40 °C, matching the ambient conditions of most control enclosures, while insulation class 155 allows the winding system to withstand elevated copper temperatures during cyclic overloads without degradation. The standard mechanical design supports direct mounting to steel frames, provided airflow around the cooling ribs remains unobstructed.
