Product Description:

The MSK071D-0300-NN-S1-BP1-NNAN is an IndraDyn S synchronous servomotor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. Its 071 frame and D-length housing establish the mechanical envelope, and the reduced run-out design minimizes radial deviation for precise positioning in pick-and-place gantries and indexing tables. The motor is intended for servo applications that require repeatable acceleration, controlled stopping, and stable motion under changing loads. That combination makes it suitable for medium-inertia axes where mounting space is limited but positioning accuracy remains important. Winding code 0300 identifies the stator configuration used with IndraDrive power stages and supports closed-loop speed and torque control in industrial automation cells.

Thermal management is handled by natural convection, eliminating the need for forced-air accessories. Because cooling is passive, the motor can be used where lower acoustic output and simpler external airflow arrangements are preferred. Position feedback reaches the drive through a Hiperface interface that carries the optical encoder's 128 signal periods for fine commutation. An electrically released holding brake delivers 23 Nm of static torque to secure vertical axes when power is removed. The housing meets the IP65 rating, so dust and low-pressure water jets do not compromise internal components. Continuous duty is permitted at ambient temperatures from 0–40 °C when proper clearance is maintained.

The feedback element is a single-turn disk, allowing absolute position capture over one mechanical revolution without the complexity of multi-turn gearing. This arrangement supports consistent position tracking during startup, normal axis motion, and controlled stopping. Power conductors terminate on the B-side, simplifying cable routing when the motor is mounted against bulkheads. Torque is transmitted through a shaft with keyway, so standard keyed couplings can be installed without custom hubs. The brake and encoder arrangement help the drive maintain stable axis behavior during power-up and operation. Insulation class 155 safeguards the winding system against thermal aging during continuous operation.
