Le HG-SR702B belongs to Mitsubishi Electric’s HG-SR series of rotary AC servo motors within the MELSERVO-J4 ecosystem, optimized for medium-inertia loads requiring high torque and precise positioning. Noté à 7 kW avec 33.4 Nm couple continu (100 Nm peak) à 2000 tr/min (3000 rpm max), it delivers exceptional performance for high-power axes in injection molding, CNC machining, robotique, and heavy material handling. Le medium rotor inertia of 161 kg·cm² enables smooth acceleration/deceleration for cyclic operations, alors que 26 Un courant nominal ensures compatibility with J4 amplifiers like MR-J4 series.
Key features include a built-in holding brake (typiquement 100 Nm holding torque), straight shaft for direct coupling, et IP67 protection against dust/water for harsh factory environments. L'intégré 22-bit absolute encoder (4,194,304 ppr) provides high-resolution feedback for precise multi-turn positioning without batteries, supporting advanced functions like absolute accuracy and vibration suppression. Dimensions are 176 x 176 x 268 mm avec 33 kg weight, and it operates on 3-phase 200 ACC with natural convection cooling.
This motor excels in applications demanding stable low-speed torque, high overload capacity, et maintenance-free operation, such as large conveyors, presses, and multi-axis gantries. It’s fully compatible with MR-J4 drives for auto-tuning, real-time auto-tuning, and network integration (CC-Link IE, EtherNet/IP).
