Product Description:
The MHD115C-058-NG1-AA is a servo motor built by Bosch Rexroth Indramat for the MHD Synchronous Motors series. Within industrial automation, this motor supplies closed-loop rotary motion for axes that need precise velocity and torque control. It is suited for positioning and synchronized motion tasks where stable feedback is needed through acceleration, steady running, and stopping. It employs a plain shaft to transmit torque directly to the driven load, and the integrated output connector on side A simplifies cabling when the motor is mounted inside a machine frame.
The unit delivers a continuous standstill torque of 70.0 Nm, allowing heavy loads to be held without overheating, while heat is dissipated through natural convection. A flange diameter of 192 mm and a centering diameter of 180 mm align the housing accurately on the machine interface. This mounting geometry helps keep the housing properly centered on the machine face during installation and operation. The housing is sealed to IP65, so dust and nozzle-directed water cannot reach internal windings, and the windings use Class F insulation for a 155 °C temperature limit. A shaft seal is present on the plain shaft to help prevent lubricant escape along the journal, and the motor uses length code C, size 115, and winding code 058.
For holding duty during power loss, the motor is supplied with a holding brake that clamps the shaft when electrical power is removed. Position feedback is generated by a digital servo feedback (HSF) encoder that uses an optical measurement method and reports relative position with a system accuracy of ± 0.5 angular minutes. This feedback arrangement allows the drive to monitor rotor movement continuously during operation. Operation is permitted up to 1000 m above mean sea level, at ambient temperatures from 0 to 40 °C, and in storage from -20 to +80 °C. The power lead exits on side A through the output connector, and the shaft seal helps protect the shaft end.
