Product Description:
The MHD115B-024-NP1-AA is a servo motor manufactured by Bosch Rexroth Indramat within the MHD Synchronous Motors series. Built for closed-loop industrial axes, it converts drive-controller output into precise rotary motion for positioning tables, gantries, and transfer stations. A keyed shaft, digital feedback interface, and side-mounted power connector allow direct integration into compact mechanical frames without external transducers. It is intended for applications that need repeatable positioning and steady speed regulation during frequent start-stop cycles.
At standstill, the motor can deliver 50.0 Nm of continuous torque, enabling it to hold loads continuously under natural-convection cooling. For vertical axes, the integrated brake supplies a holding torque of 70.0 Nm, locking the rotor when power is removed. Position data is returned through Digital servo feedback (HSF); this optical sensor supplies high resolution for tight velocity loops. The encoder output allows the connected drive to monitor rotor movement continuously during positioning and speed control. A housing sealed to IP65 prevents dust and water jets from reaching the windings or encoder. Combined with the integrated feedback path, the motor achieves a total positioning precision of ± 0.5 angular minutes. Insulation class F, optical measurement, and relative position detection support repeated motion cycles in demanding automation service.
For mechanical alignment, the stator seats against a flange of 192 mm with a locating pilot diameter of 180 mm, centering the motor to the driven load. The centering fit helps maintain alignment between the motor and the driven mechanism during installation. Power and brake conductors exit toward side A through an output connector, which can simplify cable routing in compact cabinets. A keyed shaft and shaft seal support reliable torque transfer while limiting contaminant entry. The motor operates in ambient temperatures from 0 to 40 °C and can be stored from -20 to 80 °C, and it can be used up to 1000 m above sea level. Frame size 115, length code B, and winding code 024 indicate the electromagnetic characteristics required by the selected drive module.
