Product Description:

The MSK101E-0200-NN-S1-RG2-NNNN servomotor is produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. As an IndraDyn S synchronous servomotor, it converts drive controller commands into precise rotary motion for positioning and feed axes in automated assembly lines, packaging stations, and metal-cutting centers. Size 101 and length code E place the unit among the larger torque variants while still using the standard mechanical envelope common to modular machine frames. The motor is intended for servo applications that require repeatable acceleration, stable speed control, and accurate stopping at commanded positions. This operating role makes it suitable for axes that must synchronize motion with upstream controls and machine timing.

Cooling relies on natural convection, and the motor is designated cooling type FN, so heat is removed without auxiliary fans. Feedback is transferred through the Hiperface bidirectional interface, and its scanning disk yields 128 signal periods for closed-loop position control. Position holding during power-off is provided by an electrically released brake with 70 Nm of static torque. The housing is sealed to IP65, which helps keep out dust and low-pressure water jets. The encoder uses optical sensors in a single-turn arrangement, which reduces wiring complexity while maintaining absolute position data. Because cooling is passive, the motor can be installed where fan maintenance or managed airflow is undesirable.

Mechanical connection uses a plain shaft with no keyway, simplifying coupling to backlash-free clamping hubs. The power lead exits on the motor’s right side, which supports orderly cable routing where the harness must stay clear of moving axis components. Continuous service is permitted within an ambient range of 0 to 40 °C, and operation outside this range requires derating or additional cooling. The motor uses insulation class 155 to protect the windings at elevated temperatures. This configuration is often used with direct couplings that need low backlash and consistent shaft alignment. The internal winding code 0200 indicates the electrical resistance and inductance values expected by matched IndraDrive controllers.
