Product Description:

The GAM1A4010F0CRK3 is an AC servo motor produced by Sanyo Denki within the G SANMOTION AC Servo Motors series. It is intended for positioning or speed-regulated axes in industrial automation where compact dimensions and rapid response are important. A 40 mm square flange allows the motor to connect to small machine frames, while a 30 mm pilot centers the housing against gearheads or mounting surfaces. The 8 mm shaft includes a 12 mm keyway so pulleys or couplings can transmit torque without slipping. A batteryless absolute encoder attached to the rotor supplies multi-turn position data to the drive, eliminating maintenance associated with battery replacement.

The continuous mechanical output is rated at 100 W at a nominal speed of 3000 rpm. Under these operating conditions, the armature draws 0.99 Arms, and torque changes in proportion to the constant of 0.367 N·m/Arms. The motor operates with a 100 VAC drive system, keeping copper loss moderate during sustained operation. Its 127 mm overall length provides space for the windings, rotor, and feedback assembly while retaining a compact profile. Heat produced by electrical losses is conducted through the aluminum frame and transferred to the connected mounting surface.

During acceleration or transient load changes, the drive may command up to 3.6 Arms. This peak current provides additional torque for short operating periods without demagnetizing the rotor. The winding has a phase resistance of 9.0 Ω, allowing the drive to regulate its current loop according to the motor’s electrical behavior. Rotor feedback has a 23-bit resolution, enabling precise position measurement on micro-indexed stages. An integral holding brake uses 0.26 A of coil current and secures vertical loads when motor power is removed. These features support use in compact pick-and-place heads, semiconductor handling equipment, and laboratory automation axes that require controlled movement and reliable load retention.
