Product Description:

The MHD112B-058-NP0-AN is a servo motor produced by Bosch Rexroth Indramat for the MHD Synchronous Motors series. It is designed to pair with Rexroth drive controllers and convert commanded current into regulated mechanical rotation. This makes the unit suitable for axes that require fast acceleration, constant speed, and accurate positioning in transfer lines, pick-and-place modules, and CNC stations. Integrated feedback lets the connected drive correct speed and position during operation, which helps maintain repeatable motion under changing loads. It is suited to applications that cycle frequently because the motor can respond quickly to changing command values from the controller. Its liquid-tight housing supports closed-loop motion control in enclosed industrial equipment.

A centering shoulder of 130 mm aligns the housing concentrically to the load, while the square flange spans 192 mm to match common ISO mounting patterns. The motor size of 112 gives the electromagnetic envelope, and length code B indicates a medium axial stack that balances torque and mass. The square flange provides a stable mounting face for direct installation on machine frames or gearbox adapters. The keyed shaft uses a shaft seal to secure couplings and limit contaminant entry at the output end. Electrical power exits through a connector on side A, which can simplify cable routing where clearance is limited. Internally, winding code 058 is used for the intended continuous current range.

The motor delivers a continuous standstill torque of 28.0 Nm, allowing the axis to hold static loads without overheating. Heat from the windings is removed through liquid cooling, so rated torque can be sustained in tightly packed machines. Rotor position is monitored by digital servo feedback (HSF), and the control system tracks movement through a relative position model. This arrangement supports electronic commutation and consistent motion feedback across normal operating speeds. Because the motor is supplied without a holding brake, vertical axes require mechanical clamping or drive torque during power loss.
