Product Description:
The MHD131D-024-NP2-BN is a servo motor engineered by Bosch Rexroth Indramat for the MHD Synchronous Motors series. Designed for closed-loop axes in packaging, printing, and general automation, the unit converts drive current into tightly controlled mechanical rotation. Its keyed output shaft couples directly to gearboxes or belt pulleys, while the integrated encoder supplies position signals so motion controllers can supervise speed, torque, and absolute position. This arrangement supports repeatable motion on axes that must start, stop, and hold position throughout automatic production cycles.
It delivers a continuous standstill torque of 160 Nm, enabling heavy loads to remain fixed without overheating during normal operation. Heat at this load is removed by liquid cooling, so rated output can be maintained where airflow is limited. The housing carries an IP65 rating that blocks dust and resists low-pressure water jets. A 250 mm centering diameter aligns the flange accurately to the machine face for stable mounting. Position accuracy is within ±0.5 arcminutes because the optical feedback system uses relative detection. The motor has length D and frame size 131, and it uses a keyed shaft with a shaft seal. The power leads are routed through an output connector on side B, and winding code 024 identifies the stator's electrical characteristics.
A holding brake rated at 240 Nm secures the axis during power-off conditions or emergency stops and releases automatically when current is restored. Operation is permitted between 0 to 40 °C, while storage from -20 to +80 °C helps protect materials during transport and inactive periods. The motor can be installed up to 1000 m above mean sea level without derating, and its windings use Class F insulation to tolerate elevated internal temperatures. Position feedback is generated by Digital servo feedback (HSF), allowing fast control-loop response for demanding motion tasks. This feedback arrangement supports precise regulation of rotor position and speed during continuous industrial use.
