Product Description:

The MHD093C-058-PG2-BA is a servo motor produced by Bosch Rexroth Indramat for the MHD Synchronous Motors series. As a permanent-magnet unit with integrated digital feedback, it provides closed-loop speed and position control for synchronized axes in automated machinery and transfer lines. Its encoder supports absolute feedback over more than 4096 revolutions, so the axis can retain position information through power cycles and restart without a homing move after an interruption. The feedback system also allows the drive to monitor rotor position continuously during indexing and coordinated motion.

This model delivers a continuous standstill torque of 23.0 Nm, which provides steady holding force during low-speed operation without overheating. The spring-applied brake can resist up to 32.0 Nm, helping the motor hold position when power is removed. The combination of motor torque and brake torque suits axes that must remain stable during stopping and restart. A positioning accuracy of ± 0.5 angular minutes is supported by the integrated optical encoder, and the housing is sealed to IP65 to resist dust and low-pressure water jets. The motor operates in ambient temperatures from 0 to 40 °C.

Storage temperatures from −20 to +80 °C allow the unit to be kept out of service without special climate control. A 130 mm centering diameter and a plain shaft help align the motor with geared or belt-driven loads, while a shaft seal helps block contamination at the output end. Cooling is provided by natural convection, which suits installations where forced airflow is not available. The motor also has a 140/150 mm flange, size code 093, winding code 058, insulation class F, motor length C, a power connector on side B, terminal-style output connections, and a maximum mounting altitude of 1000 m above mean sea level. The side B connector orientation can simplify cable routing where space near the driven load is limited.
