Product Description:

The MHP090B-058-HG0-UNNNNN is a synchronous servo motor produced by Bosch Rexroth Indramat and belongs to the MHP Synchronous Motors series. Designed for automated machinery, the motor converts drive commands from a compatible inverter into rotary motion with precise speed and position control for packaging lines, pick-and-place stations, or indexing tables. Its sealed housing allows direct mounting inside production cells without auxiliary enclosures. The unit is intended for closed-loop servo axes that require consistent torque output and stable thermal behavior during repeated motion cycles.

At a standstill under natural convection, the motor can deliver 12.0 Nm of continuous torque, which indicates the continuous torque available while the shaft is stationary and winding temperature remains within the rated limit. The enclosure carries an IP65 rating, so dust ingress is prevented and water jets will not impair operation. Operation is permitted between 0 to +40 °C, matching common industrial ambient conditions. Position data are reported through an incremental encoder with 2048 increments, enabling fine interpolation in high-resolution servo loops. Class F insulation allows the stator to reach elevated temperatures without dielectric breakdown. Power is fed through a rotatable connector that can be turned 270°, which allows flexible cable outlet positioning in cramped machines. A plain shaft with a sealing ring supports direct coupling while helping block lubricant migration.

The frame size 090 establishes the mounting pattern, and the length code B indicates the axial stack used for this model. Electromagnetic characteristics follow winding code 058, so the drive parameters must match that selection to prevent improper current loading. No holding brake is installed, so the rotor can spin freely when power is removed.
