Product Description:

The GAM2A4010F0CNK3 is a compact AC servo motor produced by Sanyo Denki within the G SANMOTION AC Servo Motors series. As a rotary actuator for industrial automation, it converts drive current into precise mechanical motion so that positioning tables, pick-and-place heads, and small conveyors can follow controller commands with minimal lag. The unit integrates a single-turn absolute encoder that provides shaft-angle feedback as soon as the system starts. Its keyed shaft transmits torque directly to compatible couplings or pulleys without requiring an additional shaft adapter.

Under continuous duty, the motor supplies 100 W of mechanical output while operating at a rated speed of 3000 rpm. At this operating point, it delivers a continuous torque of 0.318 N·m and draws 0.99 A rms from the drive amplifier. The copper windings have a phase resistance of 9.0 Ω, which affects current rise time and the required drive voltage. A torque constant of 0.367 N·m/A rms relates electromagnetic torque to stator current and supports accurate current control. The housing has a motor length of 105.5 mm, while the rotor inertia is 0.0670 × 10⁻⁴ kg·m² for rapid acceleration with light loads. A factory-installed oil seal protects the internal bearings from lubricant leakage and contaminant entry. The assembly weighs 0.58 kg, which limits the mechanical load placed on compact machine structures and miniature motion axes.

For short-duration operation, the servo tolerates shaft speeds up to 6500 rpm, enabling rapid positioning moves and quick indexing cycles. The rotor can provide a peak stall torque of 1.18 N·m while the drive supplies up to 3.6 A rms for brief intervals. These peak values accommodate temporary acceleration demands without treating them as continuous operating conditions. The holding brake operates from 24 VDC ±10% and secures the shaft when motor power is removed, preventing vertical loads from drifting. Its integrated placement avoids the need for a separate external locking device on axes that require stationary load retention.
