Product Description:

The GAM2A4015V0CNK0 is a compact AC servo motor produced by Sanyo Denki within the G SANMOTION AC Servo Motors series. Designed for precision axis control in industrial automation, the unit converts electrical commands from a servo amplifier into controlled rotary motion for positioning stages, small conveyors, or pick-and-place heads. Its 40 mm square flange and 8 mm shaft allow direct coupling to miniature gearheads and pulleys while keeping inertia low for responsive speed and torque regulation. This compact profile also allows the motor to fit within machines where available mounting space is limited.

During continuous operation, the motor delivers rated mechanical power of 0.15 kW at a rated speed of 3000 rpm, producing 0.48 N·m of shaft torque while drawing 1.20 A rms from the drive. Its electromagnetic conversion characteristic is represented by a torque constant of 0.441 N·m/A rms, allowing commanded current to be translated into predicted load torque during tuning. The phase resistance is 8.0 Ω, which determines copper loss under steady-state conditions and influences temperature rise. The rotor inertia with the brake is 0.0946 × 10⁻⁴ kg·m², supporting quick acceleration without excessive overshoot. The motor can be paired with a single-axis amplifier rated at 10 A or a two-axis module rated at 20 A per axis, providing options for single-axis and multi-axis machine configurations.

For dynamic movement, the motor can accelerate to a maximum speed of 6500 rpm and withstand a peak stall torque of 1.7 N·m with up to 4.3 A rms of phase current. The digital encoder transmits feedback at 4.0 Mbps and provides 8,388,608 counts per revolution (23-bit), allowing fine position interpolation and low quantization error in high-resolution motion loops. The small rotor inertia helps the shaft reach its target speed quickly during short indexing movements. Peak operating values apply to brief acceleration or overload periods, while sustained operation must remain within the continuous power, speed, torque, and current limits. The encoder’s high count density supports precise feedback for applications that require small incremental movements and stable low-speed control.
