Product Description:

The GAM1A4005F0XNK1 is a compact synchronous servo motor built by Sanyo Denki and offered in the G SANMOTION AC Servo Motors series. Designed for integration into positioning axes and light-duty actuators, the unit converts command current from a matching amplifier into precise shaft motion that can cycle rapidly without feedback loss. Its low inertia and small mounting pattern make it suitable for pick-and-place heads, miniature conveyors, and semiconductor tooling where tight speed regulation is required.

The motor delivers a rated mechanical output of 50 W when energized by a three-phase drive that supplies 200 VAC. Under rated operating conditions, the shaft turns at 3000 rpm and produces a continuous load torque of 0.159 N·m. When the axis is held at a standstill, the electromagnetic design sustains 0.167 N·m without overheating. The motor can also produce momentary peak torque of up to 0.56 N·m for movements that demand rapid acceleration. Phase resistance is 7.0 Ω, which influences current draw and thermal rise in the windings. These operating limits allow the motion controller to regulate continuous and intermittent loads while protecting the motor from excessive current.

Control precision is supported by a single-turn absolute encoder with a 20-bit resolution, allowing the drive to distinguish 1,048,576 shaft positions per revolution. The magnetic circuit couples torque to current through a constant of 0.244 N·m/Arms, providing a linear relationship for feedforward compensation during high-speed movements. Mechanical integration is simplified by the 40 mm square flange, while a circular shaft without a key supports secure attachment with a suitable clamping coupling. A factory-installed oil seal protects the bearings from external fluids. The rotor inertia is 0.0153 × 10⁻⁴ kg·m², allowing the motor to accelerate quickly and settle rapidly without excessive overshoot.
