Product Description:

The GAM2A4003F0CNK0 is an AC servo motor manufactured by Sanyo Denki for the G SANMOTION AC Servo Motors series. Intended for closed-loop positioning and speed control in pick-and-place stations, small indexing tables, and similar automation axes, the unit pairs with a matching Sanyo Denki amplifier to deliver precise rotary motion. Its built-in single-turn absolute encoder sends real-time shaft position data to the drive, enabling tight velocity and torque control during continuous operation.

The rated mechanical output is 30 W, and the motor reaches this output at a shaft speed of 3000 rpm. At that operating point, it delivers 0.098 N·m of continuous torque while drawing 0.65 Arms from the 200 VAC three-phase supply. The 27-bit single-turn absolute encoder provides 134,217,728 counts per revolution, offering finer granularity than typical incremental devices and improving interpolation accuracy when the controller commands small position corrections. Continuous stall torque is 0.108 N·m, providing additional torque capacity at zero speed. The phase resistance is 10.9 Ω. With a rotor inertia of 0.0303 × 10-4 kg·m², the motor can support rapid acceleration profiles without placing excessive demand on the drive.

A 24 VDC holding brake secures vertical or intermittent-load axes when motor power is removed. Its release circuit accepts a supply of 24 VDC ±10%, and the brake can restrain the shaft with a static torque of at least 0.48 N·m. When motion resumes, the motor withstands peak torque demands of up to 0.37 N·m, drawing 2.3 Arms for short intervals before reaching its thermal limits. The electromagnetic design produces torque at a rate of 0.183 N·m/Arms, allowing the drive to predict load response accurately during dynamic movements. The brake provides stationary load retention, while the available peak torque supports brief acceleration and deceleration demands.
