The 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. Rated at 7 kW z 33.4 Nm continuous torque (100 Nm peak) Na 2000 obr./min (3000 rpm max), it delivers exceptional performance for high-power axes in injection molding, CNC machining, robotyka, and heavy material handling. The medium rotor inertia of 161 kg·cm² enables smooth acceleration/deceleration for cyclic operations, chwila 26 Prąd znamionowy ensures compatibility with J4 amplifiers like MR-J4 series.
Key features include a built-in holding brake (zazwyczaj 100 Nm holding torque), straight shaft for direct coupling, I IP67 protection against dust/water for harsh factory environments. Zintegrowany 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 z 33 kg weight, and it operates on 3-faza 200 ODKURZACZ with natural convection cooling.
This motor excels in applications demanding stable low-speed torque, high overload capacity, I 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, Sieć Ethernet/IP).
