Product Description:

The GAM2A4003F0CRK2 is an AC servo motor produced by Sanyo Denki for the G SANMOTION AC Servo Motors series. With a compact 40 mm square flange, the unit is sized for light-duty axes in semiconductor handling equipment, pick-and-place gantries, and diagnostic instruments where installation space is limited. Within an automated cell, it converts drive current into shaft torque, providing closed-loop position or velocity control through its batteryless absolute encoder. This feedback system eliminates the need for periodic battery replacement and reduces the maintenance associated with monitoring encoder battery voltage.

The motor is designed for machines powered from a 200 VAC bus and delivers a rated mechanical output of 30 W at a rated speed of 3000 rpm. At that operating point, it draws only 0.65 A RMS, while a winding impedance of 10.9 Ω helps limit current and thermal rise. The motor generates a continuous rated torque of 0.098 N·m and has a torque constant of 0.183 N·m/A RMS. These electrical characteristics support controlled operation with compatible low-power servo amplifiers. The moderate phase resistance also helps the winding maintain stable performance during repeated positioning and velocity-control cycles.

Dynamic limits include a continuous stall torque of 0.108 N·m and a peak stall torque of 0.37 N·m, supporting short bursts of force when seating parts or overcoming static friction. The rotor inertia is 0.0303 × 10⁻⁴ kg·m², allowing rapid acceleration with limited overshoot in low-mass mechanisms. A holding brake uses a 24 VDC coil to prevent load drift on vertical axes after the drive is disabled. The feedback channel provides 23-bit position data for absolute multi-turn referencing, allowing the controller to retain the axis position without a battery. The encoder resolution supports precise motion when the motor is coupled to fine-pitch screws or other high-ratio mechanical transmissions.
