Product description
Within the MDD range, MDD071C-N-030-N2T-095GB2 identifies a permanent-magnet synchronous servo motor for digital drive controllers. Frame size 071 and motor length C define its mechanical base version; the centring diameter is 95 mm. Code 030 denotes a rated speed of 3000 min⁻¹. With natural convection, continuous standstill torque is 6.6 Nm and the associated continuous current is 10.8 A. The theoretical maximum torque is 20.5 Nm, while maximum current is 48.6 A. Electrical data also include a torque constant of 0.61 Nm/A, a winding resistance of 0.85 Ohm and a winding inductance of 5.9 mH. Rotor moment of inertia is 11.9 × 10⁻⁴ kgm². The N2T version comprises digital servo feedback and an integrated multiturn absolute encoder. Mechanically, it has a plain output shaft with shaft seal. The power connector is oriented toward side B. An electrically released holding brake rated at 6.5 Nm holding torque and 24 V DC nominal voltage is part of this version. The thermal time constant is 45 minutes. The MDD071C housing has a motor length of 288 mm; the flange area is 148 mm high and centred at 95 mm. Its mechanical interface also includes four 9-mm flange holes and an output shaft measuring 19 mm in diameter and 40 mm in length. The front flange follows mounting style B5; power and feedback use separate plug connections.
