Product Description:

The MHD112A-035-PG0-AN is a servo motor manufactured by Bosch Rexroth Indramat for the MHD Synchronous Motors series. In industrial automation, it acts as an electromechanical actuator that converts controlled AC drive energy into precise rotary motion for gantry, conveyor, and indexing axes. The frame uses the 112 mechanical size with the A length code, giving the motor a compact envelope while still allowing liquid-based thermal management. By combining a digital encoder, a sealed housing, and a connectorized power exit, the unit fits well in cabinet-mounted drive systems that require continuous torque delivery with limited thermal drift. It is commonly used in closed-loop motion systems where stable speed regulation and repeatable positioning are required over long operating cycles.

A continuous standstill output of 15.0 Nm allows the shaft to sustain static load without overheating, making the motor suitable for holding duties on vertical or high-inertia loads. Heat generated during that operation is removed through liquid cooling, so the motor can maintain its rated temperature even when installed in tight mechanical frames. The centering pilot of 130 mm keeps the motor aligned with the driven equipment, and the rectangular flange pattern on a 192 mm pitch matches common mounting surfaces on compatible gearboxes and machine plates. The 035 winding code identifies the electrical winding arrangement used by the drive controller for current control and torque response. This cooling method is especially useful in applications that spend long periods at low speed or standstill, where self-ventilated motors tend to retain more heat.

Position feedback is supplied by an integrated encoder that provides absolute (>4096 revolutions) multi-turn data through digital servo feedback, so the axis can retain position information after power loss. Mechanical output is transmitted through a plain shaft, and a shaft seal helps limit lubricant migration and fluid ingress. Power conductors exit on side A through a locking output connector, which can simplify cable routing along linear axes and other compact machine layouts. Because the motor is delivered without a holding brake, any static load retention during power-off must be provided by external clamping or by the drive’s torque-holding function. This arrangement supports installations where accurate feedback, sealed motor construction, and orderly cable routing are more important than integrated braking.
