Product Description:

The MSK101E-0202-FN-M1-AG2-NNNN is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. Designed for precision motion on packaging lines, machine tools, and robotics, the unit converts controlled three-phase supply from an IndraDrive amplifier into tightly regulated shaft torque. Integrated encoder feedback and an external cooling circuit allow the motor to sustain accurate speed and position profiles over long duty cycles. Its operating concept suits dynamic axes that require repeatable acceleration, stable positioning, and consistent performance during continuous production.

The stator uses liquid cooling, identified in the type code as FN, so heat is carried away by a coolant loop instead of ambient airflow. This arrangement permits full current delivery in compact enclosures where air circulation may be limited. Position feedback is transferred through a Hiperface interface that carries both power and data to the encoder. The encoder measures rotor angle with 128 signal periods, and because it is multiturn absolute, the controller receives a unique mechanical position after every power-up without homing. An electrically released holding brake supplies 70 Nm of static torque, preventing load drift whenever the drive is disabled or an emergency stop is triggered.

The mechanical frame follows motor size 101 and length code E, giving a balanced ratio of inertia to continuous power for medium-to-large axes. A sealed housing rated IP65 blocks dust and water jets, while a plain shaft simplifies coupling to bellows, pulleys, or gearboxes. Operation is specified between 0–40 °C, which aligns with common cabinet climate limits in industrial equipment. The windings use insulation class 155 for sustained winding temperatures up to 155 °C. Additional features include winding code 0202, a standard design housing, an A-side power connector that keeps power and feedback cables on the same face, and optical encoder technology that avoids magnetic offset errors during closed-loop operation.
