Product Description:
The MHD093C-058-NG1-BN is a servo motor produced by Bosch Rexroth Indramat and assigned to the MHD Synchronous Motors series. It is used in automated axes that require closed-loop rotary motion, high positioning accuracy, and continuous-duty operation. The unit is suited to feed axes, transfer units, and other servo-driven mechanisms where the drive must regulate torque and position at the same time. Its synchronous design allows accurate response to drive commands during acceleration, deceleration, and standstill control. The motor has frame size 093 with length code C, winding code 058, and a 140/150 mm centering flange for machine mounting.
The motor can maintain a continuous standstill torque of 23.0 Nm, and heat is removed by liquid cooling through the housing to support sustained output. A sealing system rated at IP65 helps keep dust and low-pressure water jets away from internal components, while the insulation system uses class F materials with a 155 °C thermal rating. Digital position information comes from digital servo feedback (HSF) with an optical measuring method and relative position detection, and the resulting system accuracy is held within ± 0.5 angular minutes. This feedback arrangement provides the drive with the position data needed for controlled motion and repeatable axis behavior.
The installed holding brake provides 22.0 Nm of braking torque when power is removed, which helps hold the axis during emergency stops or unpowered states. A centering diameter of 130 mm aligns the housing with adjoining machine parts, and the motor is intended for ambient temperatures from 0 to 40 °C. Installation is permitted up to 1000 m above mean sea level, and power is routed through an output connector on side B of the housing. The output is transferred through a plain shaft with a shaft seal, and storage is permitted from -20 to +80 °C. The side B connector position can simplify cable routing in compact machine spaces, and the shaft arrangement supports direct coupling without a keyway.
