Product Description:

The MSK101E-0300-NN-S1-BP2-NNNN synchronous servomotor is built by Bosch Rexroth Indramat as part of the MSK IndraDyn S Synchronous Motors series. When paired with a compatible digital drive, it provides closed-loop rotary motion for tool spindles, gantry axes, and pick-and-place units in automated production lines. In servo systems, this allows the control loop to correct speed and position deviations quickly during acceleration, dwell, and reversing moves. The motor uses frame size 101 with length code E, giving it a large housing format suited to applications that need steady torque and accurate positioning. Its standard mechanical layout fits common machine interfaces used across this motor family.

The motor uses natural convection for cooling, so heat is removed through the housing without a separate fan. A Hiperface optical encoder is integrated for feedback, and the interface supports bidirectional parameter transfer through a single cable. The encoder provides 128 signal periods per revolution and is a single-turn design, so the drive receives absolute position data within one mechanical rotation. An electrically released holding brake delivers 70 Nm of static torque to hold vertical or high-inertia loads when the axis is stopped. Because cooling is passive, the motor can be used where lower acoustic output and simpler machine layouts are preferred.

The housing is rated IP65, which helps protect internal components from dust and low-pressure water jets during normal industrial use. The motor is intended for ambient temperatures from 0 to 40 °C, a range that matches many enclosed and open machine installations. Torque is transmitted through a shaft with keyway, which allows secure coupling to pulleys, pinions, or gearboxes. The stator windings use insulation rated to Class 155, supporting continuous thermal loading at elevated operating temperatures. A B-side power connection and the standard housing design support straightforward cable routing and machine integration.
