Product Description:

The MSK101D-0450-FN-S1-AG0-NNNN is a synchronous servo motor manufactured by Bosch Rexroth Indramat and assigned to the MSK IndraDyn S Synchronous Motors series. This motor functions as a compact, high-performance drive element that couples with IndraDrive amplifiers to supply closed-loop torque and speed control on machining centers, material-handling gantries, and automated assembly lines. In industrial automation, it provides repeatable shaft positioning so tooling and workpieces can follow programmed motion profiles without deviation. Its synchronous design supports accurate response to changing command values, which is useful on axes that must accelerate, settle, and repeat the same move with minimal variation.

Thermal management is handled by liquid cooling, a method that channels coolant through the stator jacket so rated torque can be maintained even in sealed cabinets. The enclosure carries a IP65 seal that blocks dust and low-pressure water jets, permitting installation on open machine frames. Position feedback is produced by a Hiperface encoder that divides each revolution into 128 signal periods. Because the sensing principle is optical, the feedback stream is not influenced by stray magnetic fields. This combination supports stable output and reliable feedback in enclosed machine sections where ambient heat can build during extended duty. The motor has a standard design, uses winding code 0450, and has power conductors that exit on the A-side. Motor size 101 and length code D indicate the active stack dimensions used with this winding.

A plain shaft transmits torque directly to couplings or belt pulleys without keyway stress. The feedback unit is a single-turn device, so absolute angle information is retained within one mechanical turn, and multi-turn counting is performed by the controller if required. The motor is supplied without a holding brake, so an external locking method is needed on vertical axes during a power interruption. Service conditions are limited to 0–40 °C, and the windings use insulation class 155, allowing the copper to reach 155 °C without exceeding thermal limits. These operating limits are intended for normal industrial environments rather than unusually hot installation areas.
