Product Description:
Bosch Rexroth Indramat’s MHD112A-024-NG1-BN belongs to the MHD Synchronous Motors series and is classified as a servo motor for closed-loop motion axes in machine tools, packaging lines, and other automated cells. The unit translates controlled drive current into precise rotary output so position, speed, and torque commands from the controller are executed repeatably on the mechanical load. Position feedback is supplied by a digital servo feedback encoder that is read optically, allowing the drive to track relative rotor movement during operation. Power conductors exit on side B through an output connector, which can simplify cabinet wiring.
At standstill, the rotor can deliver a continuous torque of 15.0 Nm, giving the drive enough margin for static holding and low-speed feed motions. Thermal energy is removed by an integrated liquid cooling circuit, allowing full-load operation without external fans, and the housing is sealed to IP65 against dust and water jets. The square mounting interface measures 192 mm across the flange, while a 130 mm centering diameter aligns the motor with gearbox or machine frames. Size 112 with length A keeps the overall envelope compact, and a plain shaft uses a shaft seal to help prevent ingress along the journal.
An internal brake applies 22.0 Nm of holding torque when the system is de-energized, safeguarding vertical or suspended loads. For contouring applications, the motor’s system accuracy is rated at ± 0.5 angular minutes, so commanded angles are followed closely over the full travel. The windings use Class F insulation, and the electrical design follows winding code 024 for resistance and inductance matching. The motor operates in ambient temperatures from 0 to 40 °C. Storage is permitted between -20 °C and +80 °C, and installation is allowed up to 1000 m above mean sea level without derating.
