Product Description:

The MHD093B-035-PG0-AN is a servo motor produced by Bosch Rexroth Indramat for the MHD Synchronous Motors series. This brushless design couples a permanent-magnet rotor with electronic commutation so that a drive controller can generate precise torque and speed commands. In industrial automation, it functions as a rotary actuator on packaging lines, gantry axes, or tool changers where repeatable motion, fast response, and stable closed-loop control are required. Its synchronous motor design is suited to applications that require frequent starts, stops, and direction changes without the brush wear associated with DC motors.

Mechanically, the motor mounts on a 140 / 150 mm square flange and aligns to the machine frame through a 130 mm centering diameter, which helps maintain concentric installation during high-speed operation. At zero speed, it can supply 17.5 Nm of continuous stall torque, allowing the motor to hold load under current control without immediate rotation. Heat is removed by liquid cooling, which supports higher current density than similarly sized air-cooled models. Motion is transferred through a plain shaft that accepts keyed or clamped couplings, and a radial shaft seal helps block coolant migration along the journal. Digital servo feedback with an integrated encoder returns rotor position to the drive, while the lack of a holding brake means static loads must be secured by closed-loop control or an external mechanism.

Electrical interfacing details complete the installation layout. The stator winding is identified as 035, and the active length corresponds to the B code within the 093 frame envelope, which provides a practical balance of inertia and torque output for general servo duty. Mains power reaches the terminals through an output connector located on side A, which helps simplify cable routing in vertical cabinets and other tight mounting spaces. The integrated measuring system provides absolute feedback for more than 4096 revolutions, so the axis can retain position information across power cycles and resume operation after a controlled stop without a reference run. This feedback arrangement also supports continuous position tracking during indexing, dwell periods, and coordinated multi-axis motion.
