Product Description:

Bosch Rexroth Indramat manufactures the MHD071A-061-PG0-UN, a servo motor in the MHD Synchronous Motors series. With motor size 071 and length code A, this unit drives machine axes that demand precise closed-loop control. Absolute position feedback covering more than 4096 revolutions is built in, so controllers can reference the shaft directly for coordinated multi-axis motion. This arrangement supports packaging, printing, and general automation equipment where repeatable positioning and quick torque response are required throughout frequent start-and-stop cycles.

The motor delivers a continuous standstill torque of 3.5 Nm. It uses winding code 061 and an F-class insulation system that withstands thermal stress during normal duty. Heat is removed through liquid cooling, allowing rated torque without external airflow. A protection rating of IP65 permits installation in dusty or splash-prone areas, while the mounting flange follows a 115 mm square pattern with a 95 mm centering diameter. Electrical connections use combined power and feedback connectors that swivel through 270°, which helps route cables in compact machine layouts. Position data arrive from digital servo feedback gathered optically, giving absolute multi-turn information to the drive controller for accurate velocity and position control.

Mechanical coupling uses a plain shaft with a shaft seal to help prevent contaminants from reaching internal components. The optical encoder offers a system accuracy of ± 0.5 angular minutes, and the unit can operate at elevations up to 1000 m above mean sea level. The motor is supplied without a holding brake, so static loads must be restrained by the drive or an external clamp when the axis is stopped. Operational temperatures range from 0 to 40 °C, while storage or transit is allowed between −20 to +80 °C. The wider storage range allows the motor to remain unpowered in warehouses or idle equipment without exceeding its stated limits.
