Product Description:

The MHD093C-058-PP0-LA is a servo motor manufactured by Bosch Rexroth Indramat for the MHD Synchronous Motors series. It serves as a directly coupled drive element in industrial automation where closed-loop velocity and position control are required. An integrated digital encoder supplies absolute position data to the drive controller, allowing the motor to execute repeatable moves without external homing routines. The feedback arrangement also supports reliable position recovery after power cycling.

At the mechanical interface, a centering pilot of 130 mm supports accurate mounting to the machine face. Cooling is provided by natural convection, which helps keep the housing temperature within Class F insulation limits without auxiliary airflow. The unit delivers a continuous standstill torque of 23.0 Nm for axes that require holding force at zero speed under current control. Its cast-aluminum enclosure carries an IP65 rating that blocks dust and low-pressure water jets. Torque is transferred through a keyed shaft, an internal shaft seal helps prevent lubricant migration, and power enters through a left-oriented connector that can simplify cable routing on compact machines. The motor is supplied without a holding brake and uses motor length code C in a 093 frame.

Operational limits span 0 to 40 °C, and storage is permitted from -20 to +80 °C. Closed-loop positioning is repeatable within ± 0.5 angular minutes because the optical absolute feedback system retains multi-turn data beyond 4096 revolutions. Mounting faces of 140 / 150 mm allow interchange with other MHD motors that use the same flange pattern. Winding code 058 identifies the electrical resistance and inductance expected by the drive. Installation is permitted up to 1000 m above mean sea level, and the internal digital servo feedback encoder communicates through a single cable to reduce external wiring.
