Product Description:
The MHD093B-058-PP1-RN is a servo motor produced by Bosch Rexroth Indramat within the MHD Synchronous Motors series. In industrial automation, it converts drive commands into controlled rotation for axes that require precise speed and position control. Integrated digital servo feedback and an absolute encoder support closed-loop operation, helping the motor maintain accurate motion in packaging, printing, and material-handling equipment. It is suited to applications that need repeatable indexing, smooth speed regulation, and stable feedback during frequent start-stop cycles.
Its electromagnetic package delivers a continuous standstill torque of 17.5 Nm, providing steady holding force while the axis remains energized at zero speed. Thermal energy is removed through liquid cooling, so rated output can be sustained without excessive surface heating. The housing carries an IP65 protection grade, which helps block dust and low-pressure water jets on factory floors. Mechanical alignment uses a 130 mm centering diameter with a 140/150 mm flange for mounting to standard machine interfaces. The stator uses winding code 058, and the insulation system meets Class F limits for winding temperatures up to 155 °C. A keyed shaft transfers torque to the driven machine, and the motor uses a right-side power connector for straightforward cable routing.
The built-in holding brake secures vertical or inertial loads with 22.0 Nm of static torque when drive power is removed. Accurate rotor position is derived from an absolute optical encoder with digital feedback, and the feedback system provides ± 0.5 angular minutes of accuracy while tracking more than 4096 revolutions. Reliable operation is permitted at ambient temperatures from 0 to 40 °C, with storage allowed from -20 °C to +80 °C and installation elevations up to 1000 m above sea level. The motor also uses a liquid-tight shaft seal and a B-length housing in the 093 frame size.
