Product Description:

The MHD071B-035-NG3-UN is a servo motor manufactured by Bosch Rexroth Indramat for the MHD Synchronous Motors series. Within motion-control systems, it converts drive commands from a controller into rotational movement for indexing tables, packaging axes, and material-handling stations that require precise closed-loop positioning. This motor is intended for applications where steady torque delivery, accurate feedback, and dependable stopping behavior are needed during repeated motion cycles. Its role is to translate electrical control signals into controlled shaft movement while supporting repeatable axis performance.

The motor develops a continuous standstill torque of 8.0 Nm and carries IP65 protection, so dust and low-pressure water jets are kept away from internal parts. Heat is removed through liquid cooling, which helps the motor maintain output in compact enclosures where airflow may be limited. Feedback is provided by digital servo feedback (HSF) that uses an optical measuring method and relative position detection for closed-loop control. The housing uses a 95 mm centering pilot and a 115 mm square mounting flange, and the motor has length code B with size code 071. It also uses winding code 035, the shaft is plain with an integral seal, the power and feedback connectors can rotate through 270°, and the windings use class F insulation for temperatures up to 155 °C.

A holding brake rated at 10.0 Nm secures the shaft when power is removed. During closed-loop operation, the system supports an accuracy of ± 0.5 angular minutes, which helps the axis hold repeatable position on automated machinery. Continuous duty is permitted at ambient temperatures from 0 to 40 °C, storage is allowed from -20 to +80 °C, and installation is permitted up to 1000 m above mean sea level. These operating limits apply to the motor in normal industrial service, including use of the shaft seal, the liquid-cooling jacket, and the relative encoder system.
