Product Description:
The MHD112C-058-NP3-BN servo motor is produced by Bosch Rexroth Indramat and is part of the MHD Synchronous Motors series. Intended for closed-loop positioning and speed control, the unit converts drive-controller power into precise rotary motion for automated gantries, presses, and packaging axes. Its integrated digital feedback allows the motor to support demanding industrial cycles while maintaining consistent synchronization with the controlling electronics.
The motor supplies a continuous stall torque of 38.0 Nm, giving equipment high holding capability during low-speed machining or dwell periods. Cooling is provided by liquid cooling through an internal jacket, allowing full output without external fans and protecting the windings from thermal saturation. An enclosure rating of IP65 guards internal parts against dust and water jets. Mechanical mounting uses a 192 mm square flange with a 130 mm centering diameter, and torque is transferred through a keyed shaft with a shaft seal. Power is routed through an output connector on side B, and position data come from an optical high-speed digital servo feedback encoder that reports relative displacement. This HSF device works with winding code 058 to support current control and reduce commutation error.
Holding is provided by an integrated brake that produces 70.0 Nm of static torque, allowing vertical or suspended loads to remain in position when power is removed. The motor operates across an ambient range of 0 to 40 °C and can be stored between -20 and 80 °C without damage. Class F insulation withstands elevated coil temperatures, and performance remains stable up to 1000 m above mean sea level. Accuracy is maintained within ± 0.5 angular minutes, and the motor uses a C-length housing with a 112-frame stator.
