Product Description:

The MHD093B-058-PP1 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MHD Synchronous Motors series. Designed for closed-loop operation with compatible drive controllers, the unit provides rapid acceleration and stable holding capability for tool positioning, indexing tables, and robotic joints. Its frame size and electrical characteristics suit medium-power axes in printing presses, material-handling gantries, and secondary packaging machines. It is also suitable for applications that require repeatable positioning and controlled speed changes over frequent duty cycles. By supplying commanded torque on demand, it supports accurate motion during repeated production cycles.

The motor uses frame size 093 with housing length B. Mechanical integration relies on a centering diameter of 130 mm and a flange pattern that fits a 140 / 150 mm square interface, so the housing can mount directly to common adapter plates. The centering shoulder helps align the motor on the machine face before the mounting bolts are tightened. Under continuous excitation at standstill, the stator produces 17.5 Nm of torque, which allows the axis to hold position or feed a load slowly without overheating. The motor includes a holding brake with a retentive moment of 22.0 Nm for power-off locking, and it uses winding code 058 for this torque class.

Dynamic feedback is provided by digital servo feedback with an integrated encoder that reports absolute (>4096 revolutions) rotor position. This allows the controller to restore commutation and position information immediately after startup without a reference move, and the stored multi-turn position data helps reduce delay after a power cycle. Power is transmitted through a keyed shaft, which supports secure torque transfer during repeated start-stop motion. An internal shaft seal helps keep lubricant and contaminants away from internal motor parts, which supports stable operation in demanding industrial service.
