Product Description:

The MKD112B-073-GP0-RN servo motor is manufactured by Bosch Rexroth Indramat as part of the MKD Synchronous Motors series. In automated machining cells and material-handling lines, this motor couples to a digital drive controller and converts electrical energy into regulated rotary motion. This allows workpieces, tooling, or carriers to follow programmed speed and position profiles with repeatable accuracy during indexing, feed motions, and coordinated axis moves.

At standstill, the motor can deliver 28.0 Nm of continuous torque, allowing the connected axis to hold loads without auxiliary braking hardware. A flange diameter of 192 mm matches the ISO mounting interface for machines that accept this frame size, while the 130 mm centering pilot aligns the housing concentrically with the driven mechanics. The enclosure carries an IP65 rating, so internal windings remain sealed against dust and water jets during washdown. Thermal limits permit operation in ambient air from 0–40 °C without derating, while size code 112 and length code B indicate the overall footprint. The motor uses a right-side power connector, and a shaft seal is fitted even though the design is supplied without a holding brake.

Electrical integration is completed with resolver feedback (RSF), and the drive uses this relative signal with a system accuracy of ±8 angular minutes to close tight velocity loops. The windings use insulation class F, supporting winding temperatures up to 155 °C during intermittent overloads. Mechanical coupling is provided by a shaft with keyway, giving positive torque transfer to pulleys or couplings without relying solely on clamping friction. Relative position detection after homing allows the axis to synchronize quickly on power-up while maintaining the precision needed for continuous interpolation tasks and repeated point-to-point moves in automated equipment with frequent cycle changes.
