Product Description:

The MHD095B-058-NG0-AN is a servo motor manufactured by Bosch Rexroth Indramat within the MHD Synchronous Motors series. As a rotary actuator for closed-loop industrial motion systems, it converts electrical energy into mechanical torque so that packaging lines, transfer stations, and handling axes reach commanded positions with repeatable precision. The unit belongs to the medium-frame range, combining the 095 motor size with a B-length stator for continuous-duty applications that require stable position control. Closed-loop operation also allows the paired drive to correct small load disturbances during indexing, transfer, and settling motions.

In continuous operation, the motor produces 17.5 Nm at standstill, and this rating indicates the maximum static load the motor can hold without overheating when the rotor is locked. This supports applications that require the axis to remain stable during short dwell periods between moves. Rotor feedback is provided by Digital servo feedback (HSF), a high-speed sensor system that supplies incremental data for fast velocity control. Mechanical centering is simplified by a 130 mm locating diameter that fits standard precision housings, while the mounting interface uses a 140 / 150 mm square flange suited to mid-capacity gearboxes and direct-drive frames. Thermal energy is removed through liquid cooling, allowing higher current density than air-cooled designs and helping keep winding temperatures within permissible limits during long production shifts.

The driveline uses a plain shaft that couples with clamp or keyless hubs, and a shaft seal helps prevent lubricant escape when the motor is positioned below reservoirs or in humid environments. Position is calculated on a relative basis, so the control system must perform a reference move after power-up to establish an absolute zero point. Power exits the stator through an output connector oriented to side A, which helps keep cable runs parallel with adjacent axes inside multi-motor cabinets. Electrical characteristics follow winding code 058, which sets the wire gauge and turns per phase for the intended voltage range, while the absence of a holding brake reduces added mass on high-speed gantries. The overall layout supports compact installation where coupling space and cable routing are limited.
