Product Description:
The MHD115B-024-NP0-BA is a servo motor produced by Bosch Rexroth Indramat as part of the MHD Synchronous Motors series. In automated machining centers, packaging lines, and material-handling stations, the unit serves as a rotary actuator that translates command signals from a drive controller into controlled mechanical motion. Its design targets applications that demand accurate feedback, repeatable positioning, and continuous torque delivery without external gearing. This type of motor is typically paired with a matched servo drive so commanded current can be converted into stable torque, controlled speed, and precise axis positioning during changing load conditions.
Its stator winding and laminated core allow a continuous standstill torque of 50.0 Nm, supporting heavy loads during low-speed phases. A centering diameter of 180 mm and a flange size of 192 mm simplify alignment with IEC-compliant gearboxes, while the keyed shaft transmits torque without slip. The motor housing is sealed to IP65, and a shaft seal helps prevent ingress at the output end. Cooling relies on natural convection, so no external blower is required. Power is routed through an output connector on side B of the frame. Digital servo feedback generated by an optical measurement method supplies relative position data with a system accuracy of ± 0.5 angular minutes. Electrical insulation conforms to class F, allowing winding temperatures up to 155 °C during cyclic duty.
For installation planning, the motor length coded as B pairs with the size 115 frame to keep axial space moderate while preserving magnetic cross-section. Continuous operation is permitted between 0 to 40 °C, and the assembly may be stored safely from -20 to +80 °C. The allowable mounting altitude reaches 1000 m above mean sea level before output derating is required. Because the motor is supplied without a holding brake, vertical axes require a separate locking or load-holding device when power is removed. The frame and length combination provides a moderate axial envelope for machines with limited installation depth.
