Product Description:
The MHD115C-035-PG1-AN servo motor is manufactured by Bosch Rexroth Indramat as part of the MHD Synchronous Motors series. In automated machining centers, printing lines, and material-handling gantries, this motor supplies regulated rotary motion that follows drive commands while returning high-resolution position data to the control system. Its 115 frame and C-length rotor stack provide a compact but high-torque package for continuous-duty axes, where stable thermal behavior and accurate feedback help maintain repeatable motion in demanding production cycles. The motor is well suited to applications that require steady low-speed torque, precise positioning, and dependable response during frequent starts, stops, and direction changes.
A centering diameter of 180 mm seats the housing precisely in the machine bore, and a square flange measuring 192 mm matches the standard bolt pattern for the 115 frame. Under coolant flow, the motor delivers 70.0 Nm of continuous standstill torque without exceeding permissible winding temperature. The built-in liquid cooling jacket removes heat from the stator so full torque remains available even at low speed. Position control relies on digital servo feedback, allowing the drive amplifier to close current, velocity, and position loops with one feedback device. Power is supplied through an output connector, which keeps the electrical connection compact and supports orderly cable routing at the motor.
The integrated holding brake applies 70 Nm to secure the load during shutdown, and mechanical transmission is through a plain shaft that accepts clamping hubs with minimal radial runout. The encoder supports absolute position detection for more than 4096 revolutions, so the axis can resume operation after power-up without a homing run. The 035 winding code sets the electrical values expected by compatible Indramat inverters. Service access is concentrated at power entry on side A, and a shaft seal helps keep coolant or lubricants out of the bearing cavity during operation.
