Product Description:

The GAM1A4010F0CRK0 is a compact AC servo motor produced by Sanyo Denki for the G SANMOTION AC Servo Motors series. It delivers closed-loop rotary motion for positioning tables, pick-and-place end effectors, and other automated machine axes. These applications demand repeatable speed and torque control during industrial production cycles.

The motor supplies a continuous mechanical output of 0.10 kW, indicating the electrical-to-mechanical power it can deliver without overheating at its nominal operating point. Its rated speed is 3000 rpm, providing the shaft velocity used when matching gear ratios or lead-screw pitches. At that speed, the shaft produces 0.318 N·m of rated torque, enabling consistent acceleration profiles for light loads. The electromagnetic design provides a torque constant of 0.372 N·m/Arms, so every ampere of drive current adds roughly one-third of a newton-meter to the output and supports predictable current-loop response. A high-resolution, battery-free absolute encoder with 23-bit feedback transmits approximately 8.4 million discrete positions per revolution. This encoder retains absolute position information across power cycles and supports accurate low-speed movement.

The maximum mechanical speed is 6500 rpm, providing headroom for rapid repositioning when needed. During transient heavy loads, the rotor can withstand a peak stall torque of 1.18 N·m, giving it a 3.7-to-1 overload ratio relative to the continuous rating. The three-phase stator has a phase resistance of 6.9 Ω, which drive controllers use to calculate thermal behavior and current limits. If an external brake is required, its coil accepts 24 VDC within a ±10 percent range, ensuring compatibility with standard machine-control power supplies. The motor also has a 40 mm square mounting flange and a round shaft without a keyway for use with clamping couplings. Its rotor inertia is 0.0324 × 10⁻⁴ kg·m², supporting quick directional changes in responsive positioning systems. A 100 V winding class supports low-voltage installations, and the shaft does not include an oil seal for applications where contamination is not a concern.
