Product Description:
The MHD093C-058-NG0-BN is a servo motor manufactured by Bosch Rexroth Indramat for the MHD Synchronous Motors series. It converts electrical input into controlled rotary motion for CNC axes, packaging stations, and other automated machinery. Its size 093, length code C, and winding code 058 indicate the motor's frame and winding combination, while a plain shaft and no holding brake suit direct coupling when external restraints are present.
Its mechanical interface begins with a centering diameter of 130 mm, which aligns the flange accurately against the machine frame and limits runout during installation. At standstill, the motor can deliver 23.0 Nm of continuous torque, providing steady force for positioning or tensioning duties without overheating. The housing is sealed to IP65, so dust and water jets do not reach internal windings, and thermal energy is removed by liquid cooling channels in the housing to support higher current density than naturally cooled units of similar size. Rotor position is reported through Digital servo feedback (HSF), an optical system that sends incremental signals to the controller for real-time commutation, while power conductors exit on side B through an output connector to keep cable loops clear of moving assemblies.
The motor operates in ambient temperatures from 0 to 40 °C, and a shaft seal helps block lubricant spray during washdown cleaning. For storage, components tolerate -20 to +80 °C, and installation is permitted up to 1000 m above mean sea level. Mounting holes on the flange follow the dual grid of 140 / 150 mm, and Class F insulation supports winding temperatures up to 155 °C. System accuracy of ± 0.5 angular minutes supports precise contouring and stable feedback response during high-speed motion.
