Product Description:

The MHD093C-035-PG1-BA is a servo motor manufactured by Bosch Rexroth Indramat for the MHD Synchronous Motors series. In automated machinery, the unit supplies closed-loop rotary motion so positioning tables, gantries, and transfer axes can move to programmed coordinates with repeatable accuracy. Its integrated encoder sends real-time position data to the drive controller, allowing fast correction of errors during acceleration, deceleration, and dwell periods. This supports stable speed control and accurate positioning when loads change during normal machine cycles. Because the motor and feedback work together as a closed-loop axis component, the drive can respond quickly to command changes and disturbances from the load.

The motor delivers a continuous standstill torque of 23.0 Nm, so it can hold a steady load at zero speed without excessive heating under rated conditions. A centering diameter of 130 mm aligns the housing precisely in a gearbox or machine frame, while a flange size of 140 / 150 mm allows attachment to two common mounting patterns. Cooling is done through natural convection, so no separate fan or liquid circuit is required. Rotor position is detected by digital servo feedback from the integrated encoder, which allows the drive to regulate current accurately and maintain smooth motion at low speed. This layout suits machine designs that need accurate pilot alignment and clear air circulation around the motor surface.

For power-off holding, an internal brake supplies 22.0 Nm of static torque to help prevent drift on vertical axes. Multi-turn position retention is available as Absolute (>4096 revolutions), which allows the control system to retain position information across more than one shaft revolution after power cycling. Power and motor-temperature leads exit on side B, which can simplify routing when the rear of the motor faces the cable track. The output uses a plain shaft, and an integral shaft seal helps limit the entry of lubricant and contaminants into the bearing area. The shaft form also allows the coupling method to be selected according to the hub used in the machine.
