Product Description:
Bosch Rexroth Indramat manufactures the MHD090B-058-PG1-UP, a servo motor in the MHD Synchronous Motors series. The unit combines winding code 058 with a B-length housing to provide medium-frame torque while keeping overall weight manageable. Its digital absolute encoder tracks more than 4096 revolutions, providing simultaneous speed and position data to the controller. Natural-convection cooling allows operation without external fans, and the sealed housing supports use in demanding packaging and handling equipment. The plain shaft design allows direct coupling to belts, pulleys, or gearboxes.
At standstill, the motor delivers a continuous torque of 12.0 Nm, allowing it to hold loads during dwell phases without overheating. The housing carries a protection level of IP65, so dust ingress is prevented and water jets do not impair operation on the production floor. For alignment, the stator registers against a pilot diameter of 110 mm, and the square mounting flange measures 140 mm on each side, matching standard IEC layouts. Within the approved operating environment, the motor may run from 0 to 40 °C without torque derating, making it suitable for most indoor plant climates.
In storage or transit, the device tolerates temperatures from -20 to +80 °C, preserving insulation and magnet strength outside the normal operating range. An integrated holding brake supplies 11.0 Nm of static torque to lock the shaft when power is removed, which is useful on vertical axes. Position repeatability is supported by a system accuracy of ± 0.5 angular minutes, achieved through optical measurement inside the encoder. To accommodate cabinet layouts, the power connector can be rotated through 270°, easing cable routing while maintaining Class F insulation and a shaft seal that help protect the windings from moisture and oil.
