Product Description:

The MHD093C-058-NG0-LN is a servo motor from Bosch Rexroth Indramat and belongs to the MHD Synchronous Motors series. In automated cells, it works with a compatible drive controller to convert commanded current into regulated torque and speed for positioning tables, palletizers, and gantry axes. This type of motor is commonly used where smooth response and repeatable positioning are required throughout the machine cycle. Electrical power enters through a left-side connector, and digital servo feedback with optical measurement supplies the relative position signals needed for controlled motion.

The motor provides a standstill torque of 23.0 Nm, allowing stable holding and low-speed operation without overheating. This output helps the axis resist load changes while remaining steady at zero speed or during slow movement. Heat generated under load is removed by liquid cooling, so the stator remains within thermal limits during extended duty cycles. The housing has an IP65 rating, which helps protect the windings and feedback electronics from dust and water jets. Coil insulation meets Class F requirements, permitting winding temperatures up to 155 °C before insulation damage becomes a concern. The motor uses a 130 mm pilot diameter to align the flange with gearboxes or machine frames, and the plain shaft includes an integrated shaft seal.

The motor can operate at ambient temperatures from 0 to 40 °C, and storage is permitted from -20 to +80 °C when condensation is avoided. Installation is allowed up to 1000 m above sea level before derating is required. Closed-loop accuracy is maintained within ±0.5 angular minutes, which supports precise positioning on repeat-motion axes. Mounting holes follow a 140/150 mm square flange pattern for compatibility with matching machine interfaces. The motor is supplied without a holding brake, so any load that must remain fixed after power removal needs external holding force. It uses winding code 058 and has motor length C within size 093.
