Product Description:

Bosch Rexroth Indramat produces the MHD093B-024-PG1-LN, a servo motor in the MHD Synchronous Motors series. It uses the 093 frame with length code B and winding code 024 to match the current requirements of compatible drive controllers. An integrated digital servo feedback encoder provides multi-turn absolute position information, allowing the axis to recover its reference after a power cycle. The unit is intended for industrial automation tasks that require precise velocity and position control during repeated cycles.

During continuous operation, the motor produces a standstill torque of 17.5 Nm, while the holding brake can lock the shaft with 22.0 Nm when power is removed. The housing circulates coolant through internal channels, and this liquid cooling arrangement helps keep stator temperature low so rated torque remains available without derating inside cabinets. The housing is rated IP65, and the stator windings use insulation class F with a 155 °C thermal limit. The motor may run in ambient temperatures from 0 to 40 °C, provided the installation height does not exceed 1000 m above mean sea level. A plain shaft transmits torque directly, and a shaft seal helps prevent lubricant escape. Power enters through a left-oriented power connector that mates with standard Rexroth cables, and the 140/150 mm flange pattern supports installation in existing machine frames.

A centering pilot of 130 mm on the mounting face establishes concentricity between the motor and the driven equipment. The encoder uses an optical measurement method and provides a system accuracy of ±0.5 angular minutes. Position is retained as absolute position over more than 4096 revolutions, so the axis does not need a homing routine after shutdown. The unit tolerates storage temperatures from -20 °C to +80 °C, allowing storage in unconditioned facilities.
