Product Description:

The MHD093B-035-PP0-RN is a servo motor built by Bosch Rexroth Indramat for the MHD Synchronous Motors series. As a closed-loop drive element, it converts electrical power into controlled rotary motion for positioning tasks in industrial automation lines, packaging stations, and CNC axes. It is intended for systems that require repeatable speed and position control during indexing, feeding, and axis interpolation. The motor is supplied without a holding brake, so static loads must be secured by external means when the axis is at a standstill.

This model develops a continuous stall torque of 17.5 Nm, and the stator windings are cooled by liquid cooling channels in the housing. Its IP65 enclosure helps keep dust and water jets away from internal components, allowing installation near machining fluids. Accuracy is supported by an optical measurement system with ±0.5 angular minutes of system error, and absolute position feedback beyond 4096 revolutions is provided by a digital encoder. That feedback arrangement allows the drive to read rotor position after power-up and maintain stable closed-loop response during dynamic motion. Winding code 035 is matched with insulation class F varnish for operation within an ambient range of 0 to 40 °C. Power is connected through a right-hand connector, and the motor uses size 093 with length code B.

Mechanical integration is aided by a centering diameter of 130 mm and a flange pitch circle of 140/150 mm, allowing direct mounting to standard gearboxes or machine frames. These dimensions support accurate alignment between the motor and the driven load during installation. A shaft seal at the output end helps block coolant ingress, and the keyed shaft supports positive torque transmission to couplings. The windings use F class insulation, and reliable startup is possible up to 1000 m above MSL. For storage, the motor withstands temperatures from -20 to +80 °C without loss of magnet strength or encoder accuracy.
