Product Description:
The GAM2A4010F0CRK2 is an AC servo motor produced by Sanyo Denki within the G SANMOTION AC Servo Motors series. The unit combines a compact frame with closed-loop feedback to position or regulate machine axes in assembly cells, electronic component placers, and miniature conveyors. Integrated battery-free absolute feedback eliminates periodic battery replacement, while the built-in holding brake keeps the load stationary whenever power is removed, allowing vertical shafts to remain fixed without external clamps.
A square flange measuring 40 mm on each side allows direct mounting to correspondingly sized gearheads or brackets. The housing has an IP67 protection rating, preventing dust ingress and protecting the enclosure during temporary immersion under applicable test conditions. With the brake fitted, the motor weighs 0.58 kg, which helps limit the load placed on gantries or robotic arms. Peak stall torque reaches 1.18 N·m, providing short bursts of torque for acceleration, while continuous operation requires 0.99 Arms from the drive. The electrical resistance is 9.0 Ω, which limits the rate of current increase during transients, and the single-axis amplifier channel must be rated for 10 A to provide the full dynamic range. The motor has a keyway shaft without an oil seal, making it suitable for light-duty couplings in areas where shaft sealing is unnecessary. Rotor inertia is 0.0670 × 10⁻⁴ kg·m², helping reduce overshoot in high-gain servo loops.
Nominal mechanical power is 0.10 kW, and the motor has a rated power rate of 15 kW/s for handling rapid load changes without exceeding winding limits. At a commanded speed of 3000 rpm, the motor develops a continuous rated torque of 0.318 N·m, supporting smooth motion for indexing tables and small pumps. The electromagnetic design provides a torque constant of 0.367 N·m/Arms, which relates drive current directly to output torque for control-loop tuning. Battery-free absolute feedback retains position information without a replaceable encoder battery. The holding brake secures the shaft after drive power is removed, while the drive controls braking and release during normal operation.
