Product Description:
The MHD112C-058-PP3-AN servo motor is manufactured by Bosch Rexroth Indramat within the MHD Synchronous Motors series. It provides controlled rotary motion for automated packaging lines, gantry axes, and indexing tables. The motor has size 112 with length code C, and a keyed shaft transfers torque without slip. The power lead exits through an output connector aimed toward side A, which eases cable runs in populated cabinets. This arrangement helps keep the connection area compact and reduces interference with nearby machine components. The design is suitable for closed-loop axes that need repeatable motion during frequent starts, stops, and position changes.
The motor delivers a continuous standstill torque of 38.0 Nm, enabling static holding or low-speed feed without overheating. The housing is sealed to IP65, and heat is removed by liquid cooling so the motor can operate in enclosed machine compartments. Mounting uses a 192 mm square flange that matches common automation gearheads, and operation is permitted in ambient temperatures from 0 to 40 °C. Position data comes from a digital servo feedback encoder with optical rotor-angle detection, and winding code 058 matches the electrical characteristics expected by compatible Indramat drive amplifiers. This feedback arrangement supports stable speed regulation and accurate position control during continuous machine cycles.
For holding and emergency stop scenarios, the integral brake supplies 70.0 Nm of retentive torque, and a shaft seal helps block coolant ingress at the coupling. The servo motor has a centering diameter of 130 mm for repeatable concentric alignment to the driven load. Feedback accuracy is maintained within ± 0.5 angular minutes, and the encoder delivers absolute (>4096 revolutions) position tracking without homing. Class F insulation supports elevated winding temperatures, storage is permitted from -20 to +80 °C, and operation is permitted up to 1000 m above mean sea level. The absolute position signal allows the axis to recover its location after restart without requiring a reference run.
