Product Description:
The MSK101E-0300-NN-S1-AG2-NNNN is an IndraDyn S synchronous servomotor built by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. This rotary unit serves as the drive element for closed-loop axes, converting regulated drive current into predictable shaft motion in packaging, woodworking, and material-handling equipment. Its size 101 frame and E housing length provide a compact but high-torque motor body, and power connects on the A-side of the stator for direct use with compatible IndraDrive systems. The motor is intended for servo applications that need repeatable positioning, controlled acceleration, and responsive speed regulation during cycling.
Heat removal is handled by natural convection, so the motor does not require external fans. An electrically released holding brake provides 70 Nm of static torque, which helps keep vertical or load-holding axes in place when drive power is removed. Position feedback comes from an optical single-turn encoder that communicates over Hiperface and delivers 128 signal periods per revolution, supporting stable velocity control at low speed. The feedback channel also gives the drive rotor position information for commutation and closed-loop control. The 0300 winding code indicates the electrical winding layout used with compatible MSK inverters and matches the motor to the appropriate drive settings.
The housing has an IP65 rating, which helps protect the windings against dust and low-pressure water jets on the machine frame. Continuous duty is permitted at ambient temperatures of 0–40 °C, and the insulation system is rated to class 155 for the expected winding temperature range. Output torque is transferred through a plain shaft, which allows direct connection to couplings, pulleys, and similar drive components. This shaft style is suited to applications that do not require a keyed shaft end or a shaft seal.
