Product Description:

The MHD090B-035 is a servo motor used in closed-loop industrial motion systems. As a permanent-magnet AC synchronous device, it converts electrical input from a compatible drive into precise mechanical rotation. In industrial automation, it is intended for positioning axes on machine tools, material-handling gantries, and packaging equipment where repeatable torque delivery and accurate speed regulation are required. It is commonly paired with drive systems that adjust current in real time so the shaft can maintain commanded motion during changing load conditions.

The centering pilot on the front flange is machined to 110 mm, giving a reference surface that aligns the stator housing with gearboxes or mounting brackets and helps control radial runout. A square flange measuring 140 mm provides the bolt pattern that carries axial loads into the machine frame. When energized at rated current, the motor can deliver 12.0 Nm of continuous torque at standstill, so holding and slow-speed feed operations remain thermally safe. The electromagnetic configuration uses winding code 035, which indicates the wire gauge and turns per phase that set the voltage constant and rated speed. Size code 090 places this unit in the mid-range of the series, balancing inertia and torque for general-purpose motion tasks. These proportions also support stable mounting on axes that see repeated starts, stops, and direction changes.

The frame length is B, which indicates a medium stack height that increases magnetic flux without the mass of a longer rotor. The motor is manufactured by Bosch Rexroth Indramat and belongs to the MHD Synchronous Motors series. Its classification as a Servo Motor means it is intended for use with digital drive controllers that provide vector-controlled current and real-time position feedback. This arrangement supports coordinated multi-axis motion where direct rotary output and consistent response are needed across repeated operating cycles.
