MHD112A-058
The MHD112A-058 is a servo motor produced by Bosch Rexroth Indramat and supplied within the MHD Synchronous Motors series. It is built for closed-loop industrial drive axes where rapid positioning, speed control, and high cycle accuracy are required. By combining permanent-magnet excitation with resolver or encoder feedback, the unit converts electrical input from a compatible drive controller into precise mechanical rotation for actuators, gantries, and packaging stations. This type of motor is commonly used on machine axes that need repeatable motion over short cycle times and dependable response during frequent starts and stops.
The motor sustains a continuous standstill torque of 15.0 Nm, so it can hold loads without overheating when the shaft is locked by the control loop. A centering pilot of 130 mm aligns the flange to the machine faceplate and helps keep radial runout within tolerance. The square flange measures 192 mm, providing a mounting pattern suited to the 112 frame class. The motor size code is 112, and the housing uses length code A; this compact length helps reduce inertia for faster acceleration. The internal layout is matched to winding code 058, supporting the rated torque while staying within insulation class limits.
The motor supports four-quadrant operation, so the shaft can source or absorb power during dynamic braking. Its electrical characteristics support accurate current vector control with a compatible drive controller, helping the axis respond consistently during speed changes, reversals, and controlled stops. Thermal behavior, connector orientation, and seal arrangement follow the standard layout used across this motor platform, which helps the unit fit enclosed machine installations with predictable cable routing. These operating traits make the motor suitable for automated equipment that depends on stable motion and consistent cycle performance.
