Product Description:
The GAM2A4005F0CRK2 is a compact AC servo motor from Sanyo Denki’s G SANMOTION AC Servo Motors series. Built on a 40 mm square flange, the unit carries an 8 mm keyed shaft and an integrated holding brake supplied at 24 VDC to maintain shaft position when idle. By pairing its batteryless absolute encoder with motion controllers, the device delivers precise position feedback without maintenance batteries, making it suitable for semiconductor handlers, miniature conveyors, and test fixtures where space and cycle accuracy are critical.
During continuous operation, the motor furnishes 50 W of mechanical output. This power is achieved while running at a nominal speed of 3000 rpm, where the shaft sustains a steady torque of 0.159 N·m. Control loops can translate current into torque through the electromagnetic constant of 0.235 N·m/A rms, permitting tight closed-loop regulation. Winding loss and thermal rise are influenced by a phase resistance of 9.3 Ω, so drives can set current limits accordingly. With the coupled brake, the rotor inertia is 0.0394 × 10⁻⁴ kg·m², enabling brisk acceleration of light loads. An overall housing length of 93 mm keeps the installation depth minimal in compact machinery.
For transient demands, the shaft withstands a peak stall torque of 0.59 N·m without demagnetization. The encoder provides 17-bit resolution, allowing 131,072 discrete counts per revolution to enhance contour accuracy at low speeds. The motor body is sealed to IP67, providing protection against dust and temporary water immersion when it is mated with appropriate connectors. A total mass of 0.48 kg reduces the moving load when the motor is installed on a gantry or robot arm. Its compact proportions also support installation in miniature conveyors, semiconductor equipment, and test fixtures with limited mounting space.
