Product Description:
The GAM2A4005F0CNK3 is a permanent-magnet AC servo motor manufactured by Sanyo Denki for the G SANMOTION AC Servo Motors series. It serves as a compact rotary actuator in industrial automation, providing closed-loop speed and position control for small pick-and-place axes, light conveyors, and compact indexing fixtures. An integral electromagnetic brake allows the shaft to lock when power is removed, supporting vertical loads without requiring external clamps. The permanent-magnet design provides responsive torque production across controlled motion cycles.
The motor delivers a continuous mechanical output of 0.05 kW at a rated speed of 3000 rpm, translating the drive’s electrical energy into a steady rated torque of 0.159 N·m. To achieve this operating point, the windings draw a rated current of 0.79 A RMS, and their copper path has a phase resistance of 9.3 Ω; these parameters influence drive sizing and thermal design. Under continuous stall conditions, the motor draws 0.80 A RMS and produces a standstill torque of 0.167 N·m, enabling it to hold low-inertia loads within its continuous operating limits. The torque constant of 0.235 N·m per A RMS provides a linear relationship between current and developed torque, which supports accurate current-loop adjustment. These electrical characteristics allow the connected servo drive to regulate torque predictably during acceleration, steady movement, and controlled holding.
Dynamic performance includes a peak stall torque of 0.59 N·m that can be sustained briefly with a peak current of 2.9 A RMS, allowing rapid acceleration or disturbance rejection. Position feedback is provided by a single-turn absolute encoder, which supplies a unique shaft position within each revolution and makes position data available immediately after power-up. The holding brake operates on 24 VDC and generates at least 0.48 N·m of static torque while drawing 0.26 A, providing secure shaft locking with modest control-panel power. A rotor inertia of 0.0394 × 10⁻⁴ kg·m² supports fast response without excessive overshoot. Continuous and peak current limits help protect the windings from excessive thermal loading during normal motion and short acceleration periods.
