Product Description:

The MHD093C-058-PP0-BN is a servo motor produced by Bosch Rexroth Indramat within the MHD Synchronous Motors series. It is intended for closed-loop positioning and speed control in industrial automation lines where compact drives are paired with digital controllers. The unit uses a keyed shaft to deliver rotary motion directly to couplings or gear stages, and its liquid-cooled housing removes losses when continuous duty is required. This arrangement supports accurate axis motion in machines that need stable feedback and consistent response to changing commands.

The motor can sustain 23.0 Nm of torque at standstill, allowing it to resist load movement without overheating during static operation. A protection rating of IP65 shields the winding and bearing zones from dust and water jets, while the jacket’s liquid cooling path helps maintain temperature during high-current cycles. Mechanical centering is handled by a 130 mm pilot diameter that mates with a 140 / 150 mm flange, and the shaft is sealed to help retain lubricant under washdown conditions. Operation is allowed between 0 to 40 °C. The motor uses frame size 093 with length code C, which gives it the corresponding overall envelope. Power is cabled to side B through an output connector, and there is no holding brake, so external means must secure vertical axes when power is removed.

Position data is gathered by a digital servo feedback encoder that uses an optical method and provides an accuracy of ± 0.5 angular minutes for precise rotor angle monitoring. Multi-turn tracking is available as absolute (>4096 revolutions), reducing the need for homing at startup after normal power cycles. The motor can be stored between -20 to +80 °C, and installation heights up to 1000 m above mean sea level are permissible without derating. The stator complies with insulation class F, supporting the thermal endurance required for the 058 winding code during repeated load changes.
