Product Description:

The MHD090B-047 is a servo motor produced by Bosch Rexroth Indramat in the MHD Synchronous Motors series. As a rotary actuator, the unit delivers controlled torque and speed to automated machinery when paired with a matching drive controller. In industrial automation, the motor converts electrical input into controlled mechanical motion for positioning, conveying, or tooling tasks. It is suitable for axes that require repeatable motion during indexing, feed, and transfer operations. When matched with the correct controller, the motor can maintain stable speed under changing load and respond quickly to command changes.

Its continuous torque at standstill is rated at 12.0 Nm. A square mounting flange measuring 140 mm aligns the housing with gearboxes or frames built on the IEC metric pattern. The motor belongs to size code 090, which places it in a mid-range frame for power density and mounting space. Precise shaft alignment is assisted by a centering pilot diameter of 110 mm, allowing repeatable installation concentricity and low runout. Electrical performance is associated with winding code 047, which corresponds to the coil resistance and inductance combination used with a matching drive. These characteristics make the motor suitable for applications that need steady torque output and accurate mechanical alignment.

The physical envelope corresponds to length designation B, which increases the active lamination stack and adds thermal mass without changing the mounting interface. Classified as a servo motor, the model supports closed-loop control of position, velocity, and torque in response to encoder feedback. The longer housing can help absorb heat during repeated duty cycles in automated equipment. The motor uses common mechanical codes, which helps it fit established mounting patterns and coupling arrangements. The unchanged interface also helps the motor fit machine layouts already sized for this frame.
