Product Description:

The MSK071E-0300-NN-S1-UP0-NSNN servo motor is produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. As an IndraDyn S synchronous servo motor, it delivers controlled torque and speed for positioning, indexing, and follow-up motion in automated assembly and material-handling equipment. Its construction supports direct mounting in machinery where accurate electrical-to-mechanical conversion is required for closed-loop drive applications. In closed-loop systems, this allows the paired drive to regulate acceleration, speed, and position with consistent motion quality.

During operation, heat leaves the stator surface by natural convection, so no fans or coolant lines are required. Rotor feedback is supplied by a Hiperface encoder that generates 128 signal periods per revolution, allowing high-resolution interpolation inside the drive. The sensing head uses an optical principle, which provides low jitter and consistent phase accuracy. Installation flexibility is improved by a connector that is rotatable through 240°, permitting the feedback cable to be routed toward the control cabinet in different motor positions. This cooling method also simplifies machine layout because no separate airflow hardware or coolant plumbing is needed around the motor body.

For axis integration, the encoder is single-turn, so absolute position within one mechanical turn is available immediately after power-up. Single-turn feedback suits axes that reference position within one revolution while relying on the drive for interpolation between encoder marks. Mechanical load is transferred through a shaft with keyway, a standard interface that resists slippage under cyclic torque. That arrangement is commonly used where couplings, pulleys, or similar drive elements must stay aligned under changing load. The frame corresponds to size 071, and the motor uses winding code 0300 for its electrical values. The housing is suitable for standard service and for areas that require explosion protection, and length category E gives the motor an extended housing format. Because the unit is supplied without a holding brake, stationary loads must be secured by external clamps or by drive-applied torque.
