Product Description:
The MHD093C-024-NG1-BA is a servo motor manufactured by Bosch Rexroth Indramat and belongs to the MHD Synchronous Motors series. Size code 093 and length designation C place the unit in the mid-frame range of the family, where it provides precise rotary motion for positioning tasks in CNC equipment, material-handling axes, and automated assembly cells. Its digital servo feedback interface couples with Rexroth drive controllers to create a closed-loop system that regulates speed and torque according to program demand.
The motor delivers a continuous standstill torque of 23.0 Nm, ensuring stable load support without overheating. Cooling is handled through natural convection, so the housing must remain exposed to airflow rather than enclosed. A protection rating of IP65 shields internal components from dust and low-pressure water jets. The mounting pilot has a diameter of 130 mm, which helps align the shaft concentrically with driven hardware. Digital servo feedback in the HSF format is produced optically and provides relative position data with a system accuracy of ± 0.5 angular minutes. The motor uses a plain shaft with a seal to help prevent lubricant leakage, and the power lead exits through a connector on side B. Safe storage is specified between -20 to +80 °C, and installation up to 1000 m above mean sea level does not require derating.
An integrated brake supplies 22.0 Nm of holding torque so vertical or suspended loads stay fixed when power is removed. Windings identified by code 024 are insulated to class F, supporting sustained thermal loads during continuous cycles. The motor operates without derating in ambient conditions of 0 to 40 °C, provided that convection paths remain clear. A flange pattern of 140 / 150 mm matches standard gearboxes. Because the feedback system is relative, the motor requires a homing routine at power-up to establish an absolute reference.
