Product Description:

The MHD115A-024-NG0-BA is a servo motor manufactured by Bosch Rexroth Indramat and belongs to the MHD Synchronous Motors series. It is used in automated machinery that requires closed-loop torque and speed control for positioning axes, conveyors, and spindle drives. The motor converts electrical energy from a drive controller into mechanical rotation while feedback helps keep motion sequences synchronized with the overall control program. Its frame size of 115 with A length gives it a medium-power mechanical envelope that fits many machine layouts without taking up excessive space.

This model delivers a continuous standstill torque of 32.0 Nm, which supports stable holding and low-speed operation in applications such as index tables or press feeds. Protection against dust and water jets is provided by an IP65 housing, so the motor can be mounted outside sealed cabinets when the installation requires it. Position data are supplied by digital servo feedback (HSF), which provides the drive with the signals needed for commutation and correction. The mounting interface uses a 192 mm flange size together with a 180 mm centering diameter for accurate alignment. Heat is removed through natural convection cooling, so no external blower is required.

Motion precision is supported by a system accuracy of ± 0.5 angular minutes, which helps the motor maintain repeatable positioning in pick-and-place and gantry axes. The output uses a plain shaft, which transmits torque without keyways and works well with clamp hubs to reduce torsional play. The motor maintains rated output across an ambient temperature range of 0 to 40 °C, and the windings use Class F insulation rated for 155 °C. Relative position detection is optical, and the power connector is located on side B. The motor does not include a holding brake, so any required holding force must be provided externally when the axis is stopped. Storage is permitted down to −20 °C, operation is allowed up to 1000 m altitude, and an integral shaft seal helps protect the bearing area.
