Product Description:
The MHD131D-012-PP0-BN servo motor is produced by Bosch Rexroth Indramat within the MHD Synchronous Motors series. Its 131 frame size provides a large stator diameter for high torque density, and as an electrically commutated permanent-magnet motor it converts drive current into controlled rotary motion for CNC axes, packaging machinery, and other automated equipment. That arrangement supports responsive torque production and repeatable positioning during start-stop cycles. The motor is intended to operate with compatible drive controllers so that velocity and position can be regulated accurately across coordinated multi-axis systems.
At standstill, the motor delivers a continuous torque of 160 Nm, indicating the load it can sustain without overheating under rated conditions. Its square flange measures 260 mm, and the 250 mm centering diameter helps align the frame with large gearboxes to reduce shaft runout. Cooling is provided by liquid cooling, which removes heat from the housing during high-RMS-current operation. An IP65 enclosure rating helps protect the interior from dust and low-pressure water jets. Position data is acquired by an integrated absolute encoder with more than 4096 revolutions of range and a system accuracy of ± 0.5 angular minutes. This feedback allows the drive to retain position information after shutdown and restart. Electrical power is routed through an output connector on side B, and the motor uses class F insulation with a D-length stator.
The motor can be stored at temperatures from -20 to +80 °C and operated steadily from 0 to 40 °C without derating. The stated storage and operating ranges cover normal handling and powered use in standard industrial service. A maximum installation altitude of 1000 m above MSL is permitted, which helps keep cooling performance and dielectric clearances within the intended range. Winding code 012 identifies the resistance and inductance values expected by the matching drive. The shaft seal helps keep coolant or spray away from the bearing set, and because the motor does not include a holding brake, the load must be secured by external clamping or drive torque when power is removed.
