Product Description:

The MKD090B-085-GP0-AN is a servo motor manufactured by Bosch Rexroth Indramat for the MKD Synchronous Motors series. As a rotary actuator, it supplies commanded torque and speed to automated axes in packaging, material-handling, and machine-tool systems. It works with intelligent drives that close the position loop electronically, allowing accurate motion control during indexing, feed, and contouring tasks. Its 090 frame size with B length gives the motor a moderate footprint that fits many machine layouts without requiring an oversized mounting area.

The stator can deliver a continuous standstill torque of 12.0 Nm, which indicates the load the motor can hold at zero speed during continuous operation. Mechanical centering uses a 110 mm pilot diameter, and the mounting flange spans 140 mm for rigid face attachment to gearboxes or machine plates. The housing is rated IP65, which keeps dust and water jets away from internal components that use Class F insulation. Shaft radial accuracy is held within ±8 angular minutes, helping the motor maintain repeatable alignment during multi-axis motion.

A Resolver feedback (RSF) element provides commutation data and supports relative position detection, so the drive can monitor rotor position during operation. The output uses a Shaft with keyway, which helps couplings transmit torque securely when matched to the application. Power and feedback connect through an output connector, and a shaft seal protects the bearing cavity where coolant or cutting fluid may be present. Service wiring exits on Side A, which can simplify cable routing when the motor is mounted near guards or machine frames. The motor operates in ambient air from 0-40 °C and is supplied without a holding brake, so static load retention must be handled by the drive or an external locking device.
