Product Description:
The MHD093C-058-PP2-BA is a servo motor produced by Bosch Rexroth Indramat for the MHD Synchronous Motors series. In automated assembly lines, it supplies closed-loop rotary motion so drive controllers can position tooling or conveyor sections with repeatable precision. Its keyed shaft transfers torque directly to couplings or gearboxes, while an integrated absolute encoder feeds position data back to the drive to maintain axis accuracy during start, stop, and directional changes.
At standstill, the motor can deliver 23.0 Nm of continuous torque, allowing mechanical loads to remain clamped without external brakes during normal duty. The housing meets the IP65 protection rating, blocking dust ingress and low-pressure water jets when the unit is mounted on open machine frames. Heat is removed by natural convection, so no external blower or liquid circuit is required. The digital feedback unit measures rotor angle optically and reports a system accuracy of ±0.5 arcminutes, enabling tight following error limits in multi-axis gantries. Position data are delivered as absolute feedback for more than 4096 revolutions, so the controller knows the shaft angle immediately after power-up and homing routines are shortened. Wiring exits on side B through an output connector, which helps keep cable routing clear around adjacent modules.
The integrated holding brake secures the shaft with 32.0 Nm of static torque whenever the drive is disabled, which is useful on vertical axes that must resist gravity when power is removed. For storage, the motor tolerates environments from -20 to +80 °C, while continuous operation is limited to ambient air between 0 to 40 °C. A centering pilot of 130 mm aligns the 140/150 mm mounting flange to gearboxes, and the F-class winding insulation withstands elevated copper temperatures produced by repetitive acceleration cycles. A maximum installation height of 1000 m above mean sea level avoids output derating, and a factory-fitted shaft seal retains lubricant when the motor is paired with gearheads.
