Product Description:

The MHD112A-058-NP0-BN servo motor is manufactured by Bosch Rexroth Indramat and belongs to the MHD Synchronous Motors series. As a rotary actuator for industrial automation, it couples to digital drive controllers to position tooling, conveyor sections, or robotic joints with repeatable precision. It uses digital servo feedback (HSF) so the control loop can correct any deviation in real time, while the keyed shaft and shaft seal support torque transmission and fluid retention. This arrangement suits machine axes that must handle frequent starts, stops, and directional changes during normal production cycles.

It produces a continuous standstill torque of 15.0 Nm, allowing stable holding or low-speed motion without thermal overload. The housing carries an IP65 ingress rating that blocks dust and water jets, and heat is removed by liquid cooling. The centering pilot measures 130 mm and the square mounting flange spans 192 mm, matching common gearbox frames. Power arrives through an output connector on side B, rotor position is captured optically by the HSF encoder, and the motor is supplied without a holding brake. Insulation class F materials, size 112 laminations, and the A-length stack are used in the motor assembly to support stable operation in demanding automation service.

The permissible service temperature ranges from 0 to 40 °C, while storage or transport conditions may reach -20 to +80 °C without degrading insulation. At installation sites up to 1000 m above MSL, the unit maintains rated output without derating. Closed-loop accuracy reaches ±0.5 angular minutes, which supports synchronized multi-axis tasks that require precise position correction. Relative position detection requires a homing cycle after each power-up. This operating method lets the controller establish a known reference point before normal motion begins.
