Product Description:

The MHD093C-058-NG1-AA is a servo motor developed by Bosch Rexroth Indramat for the MHD Synchronous Motors series. Within automated machine tools and material-handling stations, it converts electrical drive commands into controlled rotary motion for axes that demand accurate speed and position regulation. Its electromagnetic design targets medium power ranges and supports use in packaging, printing, and machining cells. The motor is suited to closed-loop applications where repeatable acceleration, stable low-speed operation, and consistent response to load changes are important.

The motor uses size 093 laminations with the longer C stack, giving additional iron volume for sustained torque during low-speed positioning tasks. At standstill, it can deliver 23.0 Nm continuously, so the axis can maintain load without excessive thermal stress. Feedback is provided by digital servo feedback (HSF), which streams high-resolution increments to the controller for tight velocity loops and accurate motion correction. A flange bolt pattern of 140 / 150 mm matches common IEC adapters, and heat leaves the housing by natural convection, which eliminates the need for an external blower. Winding code 058 indicates a voltage and current profile that pairs with standard 300 V DC bus converters.

A factory-installed holding brake supplies 22.0 Nm of static torque, locking the axis during power-off events. Power is transmitted through a plain shaft with an oil-retaining shaft seal that helps limit contaminant ingress. The motor reports motion on a relative scale, so homing is required after startup before absolute machine position is known. Precise centering in the machine frame is aided by a 130 mm pilot diameter, while power leads exit toward side A through an output connector that simplifies cable routing. This layout supports straightforward integration with couplings, gearboxes, and other driven machine elements.
