Product Description:

The GAM2A4015V0XRK2 is a compact servo motor produced by Sanyo Denki within the G SANMOTION AC Servo Motors series. It is intended for light-duty industrial automation that requires precise, closed-loop rotary motion, such as pick-and-place heads, label unwinders, or small conveyors. By combining permanent-magnet torque generation with high-resolution feedback, the unit supplies accurate speed and position control when paired with a matching drive.

The motor delivers a continuous mechanical output of 150 W while the shaft turns at a rated speed of 3000 rpm and provides 0.48 N·m of continuous torque. To reach these values, the windings draw a phase current of 1.20 A RMS from a 200 VAC three-phase supply and have a phase resistance of 8.0 Ω, allowing compact drives to power the axis without large inrush demands. The torque constant of 0.441 N·m/A RMS relates electrical current to produced torque, so control algorithms can convert current feedback directly into mechanical effort. A rotor inertia of 0.0876 × 10⁻⁴ kg·m² supports fast acceleration while minimizing overshoot, and the 80.5 mm body length fits within tight machinery spaces. The keyway shaft is supplied without an oil seal, simplifying its connection to gearheads where external lubrication control is already present.

The integrated battery-free absolute encoder provides 23-bit resolution, eliminating downtime associated with battery replacement and giving the controller 8,388,608 discrete counts per revolution. During transient moves, the motor can accelerate up to 6500 rpm and withstand a peak stall torque of 1.7 N·m without magnet demagnetization or thermal runaway. Despite these dynamic capabilities, the assembly weighs only 0.50 kg, reducing the load on linear slides and belt stages. The stator copper length and laminated core are sized to keep the temperature rise within Class B limits. The absence of an oil seal reduces shaft drag and supports efficient operation.
