Product Description:

The MHD112C-058-PP3-BN is a servo motor from Bosch Rexroth Indramat's MHD Synchronous Motors series. Designed for closed-loop axis control, it provides precise rotary motion for packaging, printing, and handling equipment. The motor uses digital servo feedback with an integrated absolute encoder that resolves more than 4096 revolutions, so the drive can read the rotor angle without a homing cycle after startup. A keyed shaft transfers torque to the load, and a shaft seal helps prevent lubricant loss during operation.

At standstill, the rotor supplies 38.0 Nm of continuous torque, which is the steady mechanical load the windings can sustain under thermal limits. Protection against dust and low-pressure water jets is classified as IP65, so the frame can be mounted outside sealed cabinets when washdown fluids are not pressurized. Heat is removed through liquid cooling passages in the housing, permitting higher current density than naturally cooled frames of the same 112 mm stator size. Closed-loop accuracy is rated at ± 0.5 angular minutes, which helps keep following error low during interpolated moves. For emergency stops, the integrated brake can hold up to 70.0 Nm, helping prevent back-driving on vertical axes.

The motor operates in ambient temperatures from 0 to 40 °C and can be stored between -20 to +80 °C without degrading the F-class insulation system. The centering pilot measures 130 mm in diameter and mates with a flange pitch circle of 192 mm for accurate mounting alignment. The C-length housing gives the motor a compact axial profile, and power is routed to side B through an output connector to match common cable layouts in multi-axis gantries. The 058 winding code and optical feedback arrangement are intended for standard Indramat drive operation, and the allowable installation height is 1000 m above mean sea level.
