Product Description:

The MSK101E-0300-FN-M1-AP2-NNNN is an IndraDyn S synchronous servo motor manufactured by Bosch Rexroth Indramat and placed within the MSK IndraDyn S Synchronous Motors series. This motor has length code E and size 101, making it suitable for closed-loop drive axes that require high positional accuracy and steady torque in industrial automation cells. It is intended for coordinated motion applications where the controller must regulate position, speed, and torque in real time. The integrated feedback system allows the drive to monitor rotor movement continuously during indexing, positioning, and speed-controlled operation. The motor is also well suited to servo-driven packaging, handling, and machine-tool axes where repeatable acceleration and smooth low-speed control are important.

This model uses liquid cooling through the FN channel, which removes heat directly from the stator jacket and supports higher continuous current than comparable air-cooled designs. Its enclosure is rated IP65, helping protect the internal windings against dust and water jets found on production equipment. An electrically released holding brake provides 70 Nm of static torque to secure vertical or suspended loads when power is removed. Feedback communication is carried over the Hiperface interface, which supports position exchange between the motor and the connected drive. Operation is intended for ambient temperatures from 0 to 40 °C, so the motor can run within its thermal limits in standard machine enclosures. The cooling layout also reduces the need for high cabinet airflow around the motor body.

The encoder uses an optical measuring principle and provides 128 signal periods per revolution of the code disc for accurate motion feedback. Its Multiturn Absolute format retains position information across multiple shaft revolutions, which helps the axis recover its location after shutdown without losing turn count. Mechanical power is transmitted through a shaft with keyway, giving a positive connection for couplings, pulleys, or gearboxes. The insulation system is class 155, matching the thermal demands of this motor design and supporting stable operation under normal load conditions. Power connection is arranged on side A, which can simplify cable routing when the motor is mounted close to the machine frame. This feedback arrangement supports controlled startup behavior and consistent tracking during moves that include frequent stops, reversals, or dwell periods.
