Product Description:
The MHD112A-058-PG0-BN is a servo motor manufactured by Bosch Rexroth Indramat and belongs to the MHD Synchronous Motors series. As a permanent-magnet AC drive element, it converts commanded electrical power into rotational motion for positioning and velocity control tasks in automated machines, packaging lines, and material handling axes. It is intended for closed-loop motion systems where stable torque delivery and accurate speed regulation are required during repeated operating cycles. In servo applications, the motor works with a compatible drive controller that regulates current, speed, and position during machine movement. This helps the axis maintain repeatable motion when load demand or process speed changes through a cycle.
The motor can hold a load at standstill with 15.0 Nm of continuous torque, which indicates how much shaft torque it can deliver under rated thermal conditions. Accurate mechanical alignment is supported by a 130 mm centering diameter that fits associated pilot mounts, while the flange face measures 192 mm for compatibility with common machine interfaces. Internal heat is removed by liquid cooling, allowing higher continuous output in compact installations than comparable air-cooled designs. Because heat is carried away through a coolant circuit, the motor can remain effective in spaces where free airflow around the housing is limited. Rotor position and speed feedback are supplied by digital servo feedback with an integrated encoder, giving the drive high-resolution data for closed-loop control. The A-length housing also helps reduce the installation depth required along the shaft axis.
The mechanical interface uses a plain shaft, making the motor suitable for clamp couplings or shrink discs while helping maintain low runout. Power cabling exits on side B, which can simplify routing when the connector is placed at the non-drive end. All three power phases terminate on an output connector, reducing installation time compared with hard-wired glands and keeping the connection point consolidated at the motor. The unit is supplied without a holding brake, so static load retention must be provided externally, and a shaft seal is installed to help limit the ingress of cutting fluids or dust. Winding code 058 indicates the electrical resistance and inductance profile expected by the matching drive inverter. This layout supports compact machine assemblies where cable bends and coupling space must be controlled.
