Product Description:

The GAM1A4005F0CRK2 is a servo motor produced by Sanyo Denki and supplied through the G SANMOTION AC Servo Motors series. This compact device is intended to deliver closed-loop rotary motion to pick-and-place heads, miniature conveyors, and other light-duty axes in automated machinery. A batteryless absolute encoder provides multi-turn position data without requiring a maintenance battery, enabling the drive to recover the shaft angle immediately after power is restored and reducing startup time in industrial automation cells.

The motor develops a continuous mechanical output of 0.05 kW at a rated shaft speed of 3000 rpm. At that operating point, it generates 0.159 N·m of torque while drawing 0.81 A RMS from the drive. The electromagnetic coupling between the stator windings and rare-earth rotor has a torque constant of 0.244 N·m/A RMS, giving the controller a predictable current-to-torque relationship for precise force regulation. The square flange measures 40 mm across, allowing direct mounting to small gearheads and compact machine assemblies. An internal holding brake clamps the shaft when it is de-energized, and the brake requires 0.26 A to release. No oil seal is fitted, so the shaft should operate in a clean environment or behind suitable external sealing hardware.

The motor provides a peak stall torque of 0.56 N·m, allowing brief overloads while indexing loads with higher inertia. Its coil resistance of 7.0 Ω helps limit winding current and associated copper losses during operation. The power stage is matched to the motor’s 100 V input class. With the holding brake installed, the rotor inertia is 0.0218 × 10⁻⁴ kg·m², supporting quick starts and stops without requiring excessive controller gain. The motor has a total mass of 0.57 kg, which minimizes the additional load placed on miniature linear slides and other compact motion assemblies.
