Product Description:

The MHD093C-058-NG0-RA is produced by Bosch Rexroth Indramat as part of the MHD Synchronous Motors series. It is a servo motor designed for precise position and velocity control in industrial automation where reliable closed-loop motion is required. When paired with a drive controller and feedback system, the unit supplies regulated torque to medium-sized axes during positioning and speed-controlled operation. It does not include an internal brake, so any required holding force must be provided by an external device. Typical use includes machine axes that require stable speed control and repeatable positioning.

The motor uses size code 093 and length class C, giving it a flange footprint of 140/150 mm with a 130 mm centering diameter for mounting alignment. A plain shaft transfers torque, and the power leads exit to the right through a power connector. Continuous stall torque reaches 23.0 Nm, and heat is removed through natural convection. The housing is sealed to IP65, helping protect internal parts from dust and low-pressure water jets. Motion feedback is provided by digital servo feedback (HSF), which uses an optical measurement method to supply relative position data to the control loop. Position error remains within ±0.5 angular minutes, allowing accurate response during load changes and commanded motion.

The motor operates at ambient temperatures from 0 to 40 °C and can be stored from -20 to 80 °C when de-energized. Installation is permitted up to 1000 m above mean sea level without derating. The windings use Class F insulation, which supports a maximum winding temperature of 155 °C. The 058 winding code indicates the electrical values used with compatible drives. A positive shaft seal helps limit lubricant escape and contaminant entry at the output side. These operating limits describe the intended thermal range for normal industrial service.
