Product Description:

The GAM1A4005F0XRK1 is an AC servo motor built by Sanyo Denki for its G SANMOTION AC Servo Motors series. Within automated machinery, this compact motor converts drive current into controlled rotary motion so positioning or speed loops can be executed with high fidelity. Its design targets small pick-and-place heads, index tables, and similar axes where precise torque delivery and feedback are required for repeatable industrial operation.

The motor delivers a peak stall torque of 0.56 N·m, giving short bursts of force for rapid acceleration without losing synchronization. During continuous duty, its output is limited by a rated torque of 0.159 N·m, a figure used when sizing the mechanism’s steady load. At the standard rated speed of 3000 rpm, this torque translates to a mechanical power of 0.05 kW, reflecting the motor’s capability to drive light fixtures and miniature gear stages. To achieve these levels, the winding draws a rated armature current of 0.81 A RMS; drive amplifiers must therefore supply this current while keeping the temperature rise within limits.

Control accuracy is supported by a torque constant of 0.244 N·m/A RMS, allowing the drive to predict output torque directly from the commanded current. The phase windings have a resistance of 7.0 Ω, which influences heat generation during low-speed holding. Mechanical integration is simplified by a square flange measuring 40 mm on each side and an 8 mm shaft supplied without a keyway, so couplings rely on a clamp or set screw. An oil seal protects the front bearing from coolant and cutting fluid, while the low rotor inertia of 0.0153 × 10⁻⁴ kg·m² helps the axis reverse direction quickly. Position feedback comes from a batteryless absolute encoder, eliminating maintenance associated with battery replacement while still reporting multi-turn position to the controller.
