Internal Product Review
The MHD090B-047-PP1-UN is a Bosch Rexroth Indramat servo motor with liquid cooling and a keyed shaft. Digital servo feedback with an integrated encoder and absolute position detection beyond 4096 revolutions support accurate, repeatable motion control. A holding brake rated at 11.0 Nm complements the 12.0 Nm continuous standstill torque, making the motor a strong choice for precise axis control.

Product Description:
The MHD090B-047-PP1-UN is an AC synchronous servo motor from the MHD Synchronous Motors series manufactured by Bosch Rexroth Indramat. Designed for industrial automation, it converts controlled electrical power into mechanical rotation for indexing tables, conveyor axes, and other motion tasks that demand high repeatability. The integrated digital feedback system allows the drive controller to monitor rotor position directly, supporting tight closed-loop regulation in both speed and torque modes. Because the feedback system is built into the motor, standard closed-loop operation does not require a separate external position sensor at the axis.
Its electromagnetic section is wound to deliver a continuous standstill torque of 12.0 Nm, so the axis can maintain load without overheating. Mechanical alignment is guided by a centering diameter of 110 mm, while the square flange measures 140 mm across to match common machine interfaces. Heat generated in the stator is removed through liquid cooling, which helps maintain stable thermal conditions when installation space is limited. The flange and centering features help the housing seat squarely against a machine plate, which supports consistent shaft alignment with couplings or gear stages. The stator uses winding code 047, and the motor body follows the B length in the 090 frame, which keeps the package compact while supporting demanding duty cycles.
A built-in holding brake provides 11.0 Nm of static torque during power-off conditions. For flexible cable routing, the power connector is rotatable through 270°, and the combined power and feedback plug reduces the number of separate connections at the motor. The feedback system provides absolute (>4096 revolutions) position data, eliminating the need for homing at startup after stored position information has been retained. Mechanical output is delivered through a keyed shaft, and a shaft seal helps protect the interior from coolant spray and dust. The brake secures the shaft at standstill, while the sealed output end helps protect internal parts in areas exposed to splash or airborne debris.
