Product Description:
The MHD112A-024-NP0-BN servo motor is built by Bosch Rexroth Indramat and belongs to the MHD Synchronous Motors series. As a servo actuator for industrial automation, it provides closed-loop rotary motion for drive controllers that need precise positioning and repeatable speed. This arrangement lets the control system correct position and velocity errors during operation. The motor size is 112 with length code A, placing it at the smaller end of the 112 mm frame family. It is intended for installations up to 1000 m above mean sea level where ambient temperatures remain within 0 to 40 °C during operation.
At standstill, the rotor can deliver 15.0 Nm of continuous torque, which supports continuous load capacity at zero speed. An enclosure rating of IP65 helps protect the housing against dust ingress and water jets during operation. Heat is carried away by liquid cooling, allowing the frame to maintain thermal balance without external airflow. Position feedback comes from digital servo feedback (HSF), which uses an optical measurement method and supports relative position detection. With a calibrated system accuracy of ± 0.5 angular minutes, the motor can support fine positional corrections under drive control. The shaft uses a keyed design, and a shaft seal helps restrict lubricant escape. Power is routed through an output connector mounted on side B of the housing.
The motor uses a centering diameter of 130 mm and a square flange that spans 192 mm, allowing direct attachment to standard gearboxes and mounting plates. Winding code 024 indicates the coil layout used with compatible MHD drives. Long-term storage tolerates temperatures from -20 to +80 °C without degrading the insulation system. Because the unit is supplied without a holding brake, static restraint must be provided by the drive electronics or external mechanics. That is especially important on vertical axes or other loads that must remain fixed when power is removed.
