Product Description:

The MHD115A-024-NP0-BA is a servo motor built by Bosch Rexroth Indramat for the MHD Synchronous Motors series. It is intended for precision rotary axes in automated machinery, where a drive controller commands position and speed through integrated encoder feedback. The motor supplies controlled torque directly to a mechanical load, making it a core element in material handling stations, packaging lines, and robotic joints.

The motor delivers a continuous standstill torque of 32.0 Nm, providing holding force during static phases of a cycle. Its enclosure carries a protection level of IP65, so dust ingress and water jets do not compromise internal windings. Rotor position is monitored with Digital servo feedback (HSF), allowing high-speed controllers to close loops on position and velocity. A 192 mm square flange with a 180 mm centering diameter aligns the housing to gearboxes or frames, while natural convection dissipates heat through the outer surface. The keyed shaft transmits torque, and power is routed through an output connector on side B to simplify harness layout. The unit is supplied without a holding brake, carries winding code 024, and has size 115 with the short A length variant.

Rotor movement is measured optically, delivering a system accuracy of ± 0.5 angular minutes once the relative position data are interpolated inside the drive. Storage is permitted from -20 to +80 °C, and operation is specified between 0 to 40 °C, so HVAC planning can keep the motor within limits. Installation altitude may reach 1000 m above mean sea level, and a shaft seal retains lubricant when ambient pressure drops. Thermal endurance is set by Class F insulation, while the relative position detection method enables precise homing routines after power-on without referencing an absolute marker.
