Product Description:

The GAM1A4005F0XNK3 is a compact synchronous servo motor from Sanyo Denki and belongs to the G SANMOTION AC Servo Motors series. In machine tools, packaging lines, and pick-and-place modules, the motor converts drive current into precise rotary motion. This controlled motion allows connected systems to execute position, speed, and torque commands with minimal following error across repetitive production cycles.

A single-turn absolute encoder provides 8,388,608 discrete positions per revolution, and its data stream moves across the serial line at 4.0 Mbps. Continuous operation is supported at a rated speed of 3000 rpm while drawing 0.81 A RMS from the drive. The motor has a torque constant of 0.244 N·m/A RMS, providing responsive electromagnetic torque as the drive regulates current. The housing has an ingress protection rating of IP67, so internal components remain sealed against dust and temporary water immersion. Phase resistance is 7.0 Ω, which limits current surge at startup, and the windings connect to a single-axis amplifier capable of 10 A peak output. A square 40 mm flange aligns the motor with miniature gearboxes and compatible mounting brackets. The shaft measures 8 mm in diameter, and its 12 mm keyway provides positive torque transfer to a coupling or driven component without slipping during acceleration and reversal.

During acceleration or transient load spikes, the winding can accept a peak stall current of 2.9 A RMS, enabling short bursts of torque beyond the continuous operating level. Rotor inertia is only 0.0153 × 10⁻⁴ kg·m², so the motor can respond quickly to changing velocity commands without imposing a large inertial load on the motion system. The body measures 79.5 mm in length, keeping installation depth low in compact multi-axis assemblies. Its compact proportions also leave more routing space for nearby feedback and power cables while preserving access to the mounting hardware.
