Product Description:

The MHD090B-035-PP1-UN is a servo motor produced by Bosch Rexroth Indramat within the MHD Synchronous Motors series. It acts as the drive source for automated axes, supplying commanded rotation to robotics, packaging tables, and material-handling equipment where precise positioning and velocity regulation are essential. Its closed-loop operation supports synchronous movement of multiple axes in coordinated production cells. The motor is suited to servo systems that require accurate acceleration, deceleration, and settling during repeated production cycles.

At standstill, the motor delivers a continuous torque of 12.0 Nm, giving the axis stable low-speed operation without thermal overload. The mounting interface uses a 140 mm square flange, and the 110 mm centering pilot keeps the housing concentric with attached mechanics. Integrated channels support liquid cooling, so waste heat is carried away by coolant instead of ambient air, which helps in confined spaces and sustained-duty applications. A keyed shaft transmits torque to pulleys or gearboxes with positive mechanical engagement. This layout supports direct coupling to common transmission components. The holding brake supplies 11.0 Nm of static torque for load retention, and the B-length 090 frame keeps the motor compact enough for medium-duty axis layouts.

The feedback system uses digital servo feedback with a multiturn encoder that tracks motion over >4096 revolutions, so absolute position remains available after power is restored. This supports axes that may turn through many cycles before returning to a reference position. Windings marked 035 match the electrical characteristics expected by compatible Indramat drives. Sealing is aided by a shaft lip ring that helps block coolant and dust from the shaft area during operation. Electrical terminations use power and feedback connectors that rotate through 270°, letting cable exits align with the machine layout without sharp bends.
