Product Description:

Sanyo Denki manufactures the GAM1A4005F0XRK3 as part of its G SANMOTION AC Servo Motors series. This AC servo motor is designed for closed-loop positioning tasks in industrial automation where compact dimensions and controllable torque are required. By converting drive current into precise shaft rotation, the unit couples directly to small timing pulleys, gearheads, or lead screws, allowing machinery to reach commanded positions repeatedly with minimal overshoot.

The motor delivers a rated mechanical output of 0.05 kW when the shaft runs at its nominal speed of 3000 rpm under continuous load. At that operating point, it sustains a torque of 0.159 N·m, providing a stable value for steady-state load calculations. A torque constant of 0.244 N·m/A RMS links the commanded phase current to the torque produced by the motor, simplifying current-loop tuning. Electrical losses are influenced by a phase resistance of 7.0 Ω, which affects I²R heating at the rated armature current of 0.81 A RMS. The continuous output, nominal speed, rated torque, torque constant, phase resistance, and armature current help determine appropriate drive settings and thermal allowances for the connected axis.

When the shaft is locked, the motor withstands a continuous stall torque of 0.167 N·m without exceeding its temperature limits. During brief transients, the stall torque can reach 0.56 N·m when the controller supplies a peak stall current of 2.9 A RMS. The active components are housed in a square flange frame measuring 40 mm across and 79.5 mm long, while a 12 mm key seated in the shaft keyway provides positive engagement with the driven component. With a rotor inertia of 0.0153 × 10⁻⁴ kg·m² and a total mass of 0.38 kg, the motor can accelerate rapidly while imposing little load on lightweight axes. Its low inertia supports frequent speed changes, and its compact frame allows installation where available mounting space is limited.
