Product Description:

The MHD071B-061-PG2-UN is a servo motor manufactured by Bosch Rexroth Indramat for the MHD Synchronous Motors series. It converts electrical energy into controlled rotary motion for industrial automation axes that need accurate speed and position control. The built-in digital servo feedback encoder provides absolute rotor position data to the drive, allowing the controller to maintain stable motion during indexing, positioning, and speed-regulated operation.

This model delivers a continuous standstill torque of 8.0 Nm, giving it the ability to hold load force without overheating when the shaft is stationary. The mechanical interface uses a 95 mm centering diameter for alignment and a square flange of 115 mm for mounting. Heat is removed through liquid cooling channels in the stator housing, which supports high current density in applications with limited airflow around the motor body. A plain shaft transmits torque without keyways, reducing runout in coupled components. Power and feedback are routed through combined connectors, which helps keep cable entry points organized in compact machine layouts.

An integrated brake provides 6.5 Nm of holding torque to help prevent axis drift when power is removed. The power connector can be rotated up to 270°, which gives more flexibility when cables must avoid nearby guards, frames, or moving machine elements. Multi-turn feedback supplies absolute position information for more than 4096 revolutions, so the axis can retain position reference after shutdowns. The stator uses winding code 061, matching the electrical characteristics expected by compatible drive converters. A shaft seal is fitted at the motor nose to limit oil or coolant ingress, helping protect the bearing area in wet or contaminated environments.
