Product Description:

The GAM2A4015V0CNK2 is an AC servo motor produced by Sanyo Denki for the G SANMOTION AC Servo Motors series. Intended for medium-precision axes, the motor interfaces with digital drives to deliver commanded motion profiles in assembly cells, electronic component handlers, or compact conveyors. Its square 40 mm flange simplifies mounting to gearheads or direct-drive loads, while the keyway shaft provides positive mechanical engagement with compatible couplings.

Under continuous duty, the motor produces 0.15 kW of mechanical power while maintaining a rated shaft speed of 3000 rpm. At that operating point, it delivers 0.48 N·m of torque and draws a continuous armature current of 1.20 A rms. A torque constant of 0.441 N·m/A rms relates stator current to developed torque, enabling the drive to predict load response accurately during current-mode control. These nominal values indicate the thermal load that the winding insulation can sustain without exceeding its temperature limits. They also provide the operating data needed to size a compatible amplifier and select suitable cable gauges.

For short bursts, the motor withstands a peak stall torque of 1.7 N·m and momentarily accepts up to 4.3 A rms, giving machines additional capacity for rapid acceleration or disturbance rejection. Rotor inertia is 0.0946 × 10⁻⁴ kg·m², allowing speed to change quickly without excessive overshoot. Position information is provided by a 23-bit single-turn absolute encoder, whose high resolution improves settling accuracy at low speeds. When the optional electromechanical brake engages, its coil draws 0.26 A and secures vertical loads whenever motor power is removed. The motor has a phase resistance of 8.0 Ω, which limits current flow through the windings. Its mass is 0.69 kg, reducing the payload added to compact gantries, and the output shaft is supplied without an oil seal for clean or low-friction assemblies.
