Product Description:

The MHD093B-058-PG1-AA is a servo motor produced by Bosch Rexroth Indramat for the MHD Synchronous Motors series. It drives rotary axes that need precise speed and position control, and its integrated digital feedback encoder allows the connected drive to read absolute rotor position over more than 4,096 revolutions. The model suits installations where a compact motor with an internal brake must deliver repeatable torque without external transmissions. It is well suited for directly coupled axes in packaging, material handling, and general automation equipment where stable motion and compact installation are important.

This motor can generate a continuous standstill torque of 17.5 Nm, meaning the shaft can hold that level indefinitely as long as thermal limits are respected. During power-off or emergency stops, the integrated brake supplies 22.0 Nm to keep the load in place. A centering diameter of 130 mm aligns the flange accurately on the machine frame, while the housing dissipates heat only through natural convection, so no fan or liquid circuit is required. The square mounting flange follows the ISO pattern of 140 / 150 mm, which supports direct installation on compatible machine interfaces. Power is routed through an output connector on side A of the stator housing, and the B-length, size 093 frame keeps mass and inertia moderate for medium-duty axes. Passive cooling also helps simplify layouts that do not have space for auxiliary airflow hardware.

A plain shaft transfers torque without keys, and a dedicated shaft seal blocks coolant or dust from entering the bearing cavity. Position detection is handled by an Absolute (>4096 revolutions) measuring system, giving the controller startup data without homing moves. Coil geometry follows winding code 058, matching the electrical resistance and inductance expected by standard HDS and DDS drives. This arrangement supports predictable motor response during acceleration, holding, and repeated positioning cycles. The sealed shaft area and enclosed feedback system also make the motor suitable for machine sections where cleanliness and dependable operation are important.
