Product Description:

The GAM2A4015V0XRK0 is a small-frame AC servo motor built by Sanyo Denki for the G SANMOTION AC Servo Motors series. As a rotary actuator, it converts commanded current from a matched drive into controlled shaft torque and speed, serving indexing tables, pick-and-place heads, and other compact axes that need precise position feedback in industrial automation. The motor integrates a high-resolution optical encoder so the drive can close the control loop without external sensors.

The stator windings are designed for a 200 VAC supply and draw a rated armature current of 1.20 Arms through a phase resistance of 8.0 Ω. At this operating point, the rotor delivers continuous shaft power of 0.15 kW and mechanical output of 0.48 N·m at a nominal speed of 3000 rpm. The absolute encoder provides 8,388,608 discrete positions per revolution. Its 23-bit resolution lets the controller maintain sub-arc-minute positioning accuracy. Thermal performance includes a rated power rate of 26 kW/s, and Sanyo Denki recommends a 305 × 305 × 12 mm heat-dissipation plate to keep the winding temperature within the insulation limits.

The motor provides a peak stall torque of 1.7 N·m, allowing short bursts above continuous torque during rapid acceleration. The electromagnetic design supports this peak by pairing a torque constant of 0.441 N·m/Arms with a low rotor inertia of 0.0876 × 10⁻⁴ kg·m², so current changes are converted into speed changes quickly. The motor has a 40 mm square mounting flange for installation in compact machinery. Its 8 mm shaft is ground to a tolerance of 0/-0.009 mm, supporting accurate alignment with couplings and driven components. A total mass of 0.50 kg minimizes the load placed on linear stages and other moving assemblies. When installed on the recommended heat-dissipation plate, the motor can sustain its rated output without exceeding the permitted temperature rise during extended operation.
