Featuring liquid cooling for efficient heat dissipation and a dual thermal time constant of 40 or 90 minutes, the MHD112C model maintains optimal operating temperatures from 0 °C to +40 °C at altitudes below 1000 m. The built-in digital servo feedback w/ integrated encoder offers absolute (>4096 revolutions) position detection, supporting precise motion control. At standstill, the motor delivers a continuous torque of 38.0 Nm, and the optional holding brake provides a 70.0 Nm holding torque for safe, static load retention. Environmental protection meets IP65 and insulation class F, safeguarding internal components against dust and moisture.
","
Performance highlights include a maximum torque of 148 Nm with a peak current draw of 239 A and a moment of inertia of 273×10⁻⁴ kg·m², enabling rapid acceleration up to 4500 rpm. Under surface cooling, the motor achieves a rated torque of 43.5 Nm, rated output of 19.4 kW at 276 V, and a torque constant of 0.8 Nm/A, making it well suited for demanding positioning tasks and continuous-duty applications.
