Product Description:

The MHD112B-048-PG0-LN is a servo motor produced by Bosch Rexroth Indramat as part of the MHD Synchronous Motors series. It is intended for closed-loop industrial axes where accurate velocity and position regulation are needed. Its integrated digital feedback reports shaft angle directly to the drive controller. This arrangement allows the motor and drive to work together for precise motion in automated machinery such as transfer systems, handling units, and positioning axes. It is suitable for machine axes that require repeatable starts, stops, and controlled acceleration under varying loads.

The motor mounts to host machinery with a centering pilot of 130 mm and a square flange that measures 192 mm across, ensuring repeatable alignment of the rotor and load. At standstill it can deliver 28.0 Nm of continuous torque, so it can maintain force during dwell periods without immediate thermal overload. Internal coolant passages support liquid cooling, moving heat into an external circuit when duty is high and continuous operation is required. A plain shaft transmits torque without keyway stress concentrations, and a shaft seal helps limit lubricant escape or particle ingress. The housing also carries a digital servo feedback encoder, so speed and position data travel through the same cable set instead of a separate resolver line.

Winding code 048 sets the resistance and inductance values that the matching drive must use. Absolute feedback covers more than 4096 revolutions, so homing routines are generally unnecessary after power restoration. Power conductors enter on the left side, and the interface uses a sealed power connector that allows connection without opening a terminal box. The motor belongs to size 112 with length B, which keeps the housing compact for its torque class. Because it is supplied without a holding brake, machines that need static load locking must rely on external clamping or motor torque.
