The Bosch Rexroth Indramat MHD112A-058-NG0-AN is a servo motor in the MHD Synchronous Motors series. It features a continuous torque at standstill of 15.0 Nm and uses liquid cooling with a protection rating of IP65. The motor has a 192 mm flange size, a plain shaft with seal, and uses digital servo feedback for relative position detection.
Internal Product Review
The Bosch Rexroth Indramat MHD112A-058-NG0-AN is a servo motor that stands out with liquid cooling and IP65 protection. Digital servo feedback and relative position detection support stable, repeatable motion control in closed-loop systems. The ±0.5 angular minute system accuracy and 15.0 Nm continuous standstill torque make the motor a very capable choice for demanding servo axes.

Product Description:
The MHD112A-058-NG0-AN is a servo motor manufactured by Bosch Rexroth Indramat and supplied within the MHD Synchronous Motors series. It is intended for closed-loop axis control where precise torque and speed regulation are needed in industrial automation cells, gantries, and packaging equipment. The synchronous design supports quick response and repeatable positioning of mounted loads commanded by an Indramat drive controller. This type of motor is commonly used on feed axes, indexing stations, and transfer systems where smooth motion and repeatable stopping points are required.
The motor produces a continuous standstill torque of 15.0 Nm, providing stable holding force for axes that dwell under load. Its housing carries an IP65 rating, so dust and low-pressure water jets do not interfere with operation when the unit is installed on open machine frames. Heat is removed through liquid cooling, allowing the stator to maintain stable operating temperature during high duty cycles without increasing frame size. Rotor position is monitored by digital servo feedback (HSF), which sends high-resolution increments to the drive controller for tight velocity control. The winding is rated for ambient temperatures from 0 to 40 °C. The motor is supplied without a holding brake, so static load retention must be handled by external mechanisms or drive torque.
A flange diameter of 130 mm aligns the motor concentrically on precision gearboxes, and the mounting interface spans 192 mm on each side to suit the 112 frame size. System repeatability is supported by an optical measurement chain that limits cumulative error to ± 0.5 angular minutes, which helps multi-axis interpolation remain consistent over repeated cycles. For storage, the unit tolerates ambient temperatures from -20 to +80 °C without degrading the Class F insulation. The motor has a plain shaft with a shaft seal, and power conductors exit on side A. The sealed shaft arrangement helps protect internal bearing areas in installations exposed to splash or airborne debris. Relative position detection supports axis startup after power is restored.
