Product Description:

The MHD095B-058-PG0-BN is a servo motor produced by Bosch Rexroth Indramat within the MHD Synchronous Motors series. Designed for closed-loop industrial automation, it provides precise rotary power using digital servo feedback with an integrated encoder. The unit combines motor size 095 with motor length B to meet medium torque requirements while remaining compact. A flange size of 140/150 mm mates with standard mounting patterns, and power exits on side B through an output connector that simplifies cabinet wiring.

Mechanical output is rated for a continuous standstill torque of 17.5 Nm, allowing the shaft to hold load without overheating when motionless. Heat generated in this condition is removed through liquid cooling, which circulates coolant around the stator jacket to keep the windings within the Class F insulation limit. The enclosure carries an IP65 rating, so dust and water jets do not reach internal components, and a shaft seal further protects the bearing set. A centering diameter of 130 mm aligns the motor on the machine face, while reliable operation is maintained across an ambient range of 0 to 40 °C. Position feedback is captured optically, which helps improve repeatability under vibration.

In motion control loops, this motor contributes finely resolved position data. Its feedback system offers a system accuracy of ±0.5 arcminutes and tracks more than 4096 revolutions in absolute mode without losing position information. The drive train benefits from a plain shaft that eliminates keyway stress and supports low-backlash couplings. The motor operates up to 1000 m above mean sea level and can be stored between −20 and +80 °C. Winding code 058 indicates the electrical constants used by the motor, and the unit is supplied without a holding brake for applications that use external clamping or drive torque to maintain position.
