Product Description:
The MHD115C-059-NP1-BN is a servo motor built by Bosch Rexroth Indramat for the MHD Synchronous Motors series. It is intended for closed-loop axis control in machine tools, packaging lines, and similar automated stations where precise rotary positioning and constant torque are required. As a brushless AC design, the motor works with compatible Indramat drive controllers to convert commanded current into controlled torque and speed at the shaft. This arrangement supports repeatable motion on axes that must accelerate, hold position, and reverse direction under controlled operation.
The motor combines mechanical and thermal features that affect installation and continuous operation. At standstill, the rotor can deliver 70.0 Nm, so the drive can hold substantial loads without external gearing. A centering diameter of 180 mm and a 192 mm square flange align the housing to the machine frame with low concentricity error. That mounting geometry helps the motor seat accurately against matching machine surfaces and keeps the shaft axis in line with couplings or gearboxes. The stator windings are supported by liquid cooling, which removes heat directly from the housing and allows full torque over extended duty cycles. The motor has an IP65 rating, which helps protect the frame against dust and water jets. Position feedback is supplied through digital servo feedback (HSF), providing high-resolution incremental signals for fast control loops, while the windings use Class F insulation to withstand internal hot-spot temperatures up to 155 °C.
The motor is intended for ambient temperatures from 0 to 40 °C, and storage is permitted down to -20 °C when the machine is idle. Optical measurement inside the encoder yields a system accuracy of ±0.5 angular minutes, which supports fine contouring on multi-axis installations. Power and brake conductors exit on side B through an output connector that can simplify cable routing when the motor is mounted near a cabinet wall or cable track. A keyed shaft provides positive torque transmission to couplings or pulleys, and a shaft seal helps limit fluid ingress around the bearing area. The integrated holding brake applies torque during power-off, and the housing can be mounted up to 1000 m above mean sea level without derating.
