Product Description:

The MHD093C-058-PG0-BA is a servo motor from Bosch Rexroth Indramat and belongs to the MHD Synchronous Motors series. It is intended to drive rotary axes in automated machinery by delivering controlled torque and speed when paired with a compatible digital drive controller. The motor integrates position feedback electronics so the control loop can maintain precise alignment with commanded motion profiles in packaging, material handling, and general production cells.

At standstill, the motor can deliver a continuous torque of 23.0 Nm, allowing it to hold or index loads without overheating during extended dwell periods. A centering diameter of 130 mm mates the housing to standard machine frames, while the square mounting flange measures 140 / 150 mm, so the motor fits directly onto gearboxes or belt drives with the same pattern. Thermal energy leaves the stator by natural convection, so no external fan or liquid circuit is required. Rotor position is measured by a digital servo feedback unit built into the rear of the housing, providing high-resolution data for tight velocity and torque loops.

The mechanical interface is a plain shaft, so power is transmitted through friction-fit couplings or keyed hubs supplied by the machine builder. Absolute position information exceeding 4096 revolutions is stored in the encoder memory, eliminating homing cycles after power loss. Winding code 058 sets the electrical resistance and inductance that the associated drive must match for optimal current control. The power leads exit the terminal block on side B and terminate on an output connector that seals against oil mist, while the shaft seal helps prevent lubricant from migrating along the journal. Motor length C and frame size 093 give a balanced ratio of thermal mass to dynamic response, and the unit is supplied without a holding brake to reduce inertia.
