Product Description:
The MSK101E-0300-NN-S3-AG2-NNNN is an IndraDyn S synchronous servomotor developed by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. The unit converts controlled AC power from an IndraDrive amplifier into precise rotary motion, supplying accurate torque and velocity for packaging lines, gantry axes, and general handling equipment. It is intended for closed-loop motion systems where repeatable acceleration, steady speed control, and consistent positioning are required during frequent production cycles. This helps the motor serve axes that cycle rapidly between acceleration, constant speed, and dwell periods.
Mechanically, the motor uses size 101 stator laminations and length variant E to increase active iron volume without altering the mounting pattern. The housing carries an IP65 rating, which protects the windings against dust and low-pressure water jets. Heat is removed by natural convection, and the FN cooling requirement means airflow around the fins must remain unobstructed. A plain shaft transmits torque directly, the power connector is located on the A-side for straightforward cable routing, and an electrically released holding brake provides 70 Nm of static torque during power-off states. Feedback is supplied through a Hiperface interface, and the integrated capacitive sensor provides 16 signal periods per revolution for commutation and position evaluation. This layout keeps the motor suitable for enclosed machinery where orderly cable routing and sealed operation are both important.
The feedback device is a single-turn encoder, so the controller receives absolute position information within one mechanical revolution while additional turns are tracked electronically by the drive. Operation is permitted in ambient temperatures from 0–40 °C, and the Class 155 insulation system supports elevated winding temperatures within the motor's thermal limits. Electrical behavior is set by winding code 0300, which establishes the resistance, inductance, and voltage constant used by the matching drive for current regulation. Because the encoder is absolute within one turn, the axis can resume controlled motion after a stop without relying only on incremental pulse tracking.
