Product Description:
The GAM2A4010F0XNK1 servo motor is produced by Sanyo Denki within the G SANMOTION AC Servo Motors series. As a compact permanent-magnet device with a 40 mm flange, it converts electrical energy from a matched amplifier into rotary motion for positioning axes in industrial automation. The motor integrates a single-turn absolute encoder, allowing a drive controller to track the shaft position after a power cycle. This feedback supports accurate closed-loop speed and torque control in packaging machines, pick-and-place units, and small conveyors.
At its nominal operating point, the motor delivers 100 W of output power while the shaft rotates steadily at 3000 rpm. The windings operate from a 200 VAC supply, and the drive limits the continuous armature current to 0.99 A rms. The corresponding continuous mechanical torque is 0.318 N·m. Torque rises proportionally with current according to a torque constant of 0.367 N·m/A rms. These values allow the controller to calculate current setpoints directly from the required load torque and help ensure adequate voltage margin during rapid acceleration. A 40 mm square flange simplifies attachment to compact gearheads, while an internal oil seal prevents lubricants from migrating along the shaft during horizontal or vertical mounting.
During transient motion, the servo can withstand a peak stall torque of 1.18 N·m, providing additional torque for short indexing movements or tension adjustments. Electrical losses remain predictable because the three-phase windings have a phase resistance of 9.0 Ω, which the drive can use to estimate winding temperature from resistive losses. Feedback accuracy is enhanced by the encoder’s 23-bit resolution, which provides 8,388,608 discrete positions per revolution and supports smooth velocity control at low speeds. The housing meets the IP67 classification, providing complete protection against dust ingress and protection against temporary immersion under the applicable test conditions. This enclosure also helps protect the internal components from moisture encountered in demanding industrial installations.
