Product Description:
The GAM2A4003F0CNK1 is a brushless AC servo motor produced by Sanyo Denki within the G SANMOTION AC Servo Motors series. This compact-frame unit is intended to drive small linear stages, indexing tables, or lightweight pick-and-place heads in automated production lines. When paired with a dedicated drive controller, the motor provides precise velocity and position control that supports repeatable movement in compact machinery. Its brushless design reduces mechanical wear associated with commutators and brushes while supporting responsive operation during frequent acceleration and deceleration cycles.
The motor uses a 40 mm square mounting flange, allowing it to connect directly to miniature gearheads or compatible size-40 brackets without adapters. The stator windings accept a nominal supply of 100 VAC, which is suitable for low-power servo axes in desktop or compact machines. Under rated operating conditions, the shaft supplies 30 W of mechanical power while turning at 3000 rpm. The motor provides a continuous output torque of 0.098 N·m at this operating point. These values allow the drive and connected load to be selected according to the motor’s continuous power, speed, and torque capabilities without exceeding its normal thermal limits.
During rapid transients, the drive can command up to 2.3 A RMS of phase current, enabling a peak stall torque of 0.37 N·m for brief acceleration or holding events. Rotor position is reported by a 23-bit single-turn absolute encoder, which provides 8,388,608 discrete counts per revolution for high-resolution feedback to the control loop. The electromagnetic design provides a torque constant of 0.183 N·m/A RMS, allowing motor torque to increase in proportion to the applied current. The holding brake draws 0.26 A, and the phase resistance is 10.9 Ω. Rotor inertia is 0.0303 × 10⁻⁴ kg·m², while the motor body has a length of 89 mm. The shaft can reach a maximum speed of 6500 rpm, providing additional speed capacity above the rated operating point for suitable short-duration motion profiles.
