Product Description:
The MHD090B-047-PG1-UN is a servo motor produced by Bosch Rexroth Indramat within the MHD Synchronous Motors series. Designed for industrial automation, it transforms regulated drive current into controlled mechanical motion so that pick-and-place axes, packaging stations, or transfer lines can execute repeatable positioning moves with minimal following error. It pairs with Indramat digital drives for coordinated multi-axis control across manufacturing cells, and its integrated feedback supports accurate speed and position regulation during continuous operation. This makes it suitable for axes that need repeatable starts, stops, and speed changes during automated cycles.
At the mechanical interface, the front face carries a 110 mm centering pilot and a square flange measuring 140 mm. This geometry aligns the size 090 frame precisely to gearboxes or machine baseplates and helps maintain shaft alignment during installation. The flange arrangement also provides a stable mounting surface for direct machine integration. Heat generated in the stator is removed by liquid cooling, allowing the motor to provide a continuous standstill torque of 12.0 Nm without exceeding normal thermal limits. Motion data are returned through digital servo feedback from the integrated encoder, enabling stable speed regulation and responsive axis control under changing loads.
A spring-applied holding brake rated at 11.0 Nm holds the shaft when control power is removed, which helps keep vertical loads in place. Position tracking uses absolute (>4096 revolutions) feedback, so the axis can resume operation after a power cycle without a reference run. The power connector can be rotated through 270°, which helps with cable routing in tight enclosures, and sealed mating surfaces help maintain protection at the connection point. Winding designation 047 matches the electrical characteristics of the motor length B version, while the combined power and feedback connection reduces cable clutter and keeps signal routing organized.
