Product Description:
The GAM2A4003F0XRK1 is a compact AC servo motor from Sanyo Denki that belongs to the G SANMOTION AC Servo Motors series. It is intended for positioning and speed-control tasks in automation equipment where a small frame and highly accurate feedback are required. The motor combines a compact housing with an integrated encoder, allowing closed-loop motion without the need for external position transducers. Its size and control characteristics suit machinery with limited installation space, including small handling systems, indexing mechanisms, and precision production equipment.
The feedback device provides a resolution of 23 bits and uses a batteryless absolute encoder, allowing position data to be retained after power is removed without maintenance batteries. A square mounting flange measuring 40 mm simplifies attachment to miniature gearboxes or direct-drive load brackets. The enclosure carries an IP67 protection rating and includes an oil seal that helps prevent water or cutting fluid from reaching the bearings during washdown operation. The motor produces a peak stall torque of 0.37 N·m for short periods of increased mechanical demand. Its stator operates from a 200 VAC supply, while the phase resistance is 10.9 Ω. Under continuous load, the motor produces 0.098 N·m at 3,000 rpm, making it suitable for light pick-and-place arms, labeling heads, and semiconductor transport stages. The smooth circular shaft supports attachment to low-backlash clamping couplings or timing pulleys without requiring a keyed connection.
The motor has a rated current of 0.65 Arms, which the accompanying amplifier must provide without causing the coil temperature to exceed its operating limit. Mechanical output power reaches 0.03 kW, matching micro-axis applications where low power consumption and compact components are important. A torque constant of 0.183 N·m/Arms allows instantaneous torque to be calculated from the measured phase current during servo adjustment. The rated speed, electrical resistance, current requirement, and output capability support selection of a compatible drive amplifier and appropriate overcurrent protection for continuous operation. Proper coupling alignment helps limit radial loading on the shaft and bearings when the motor is connected to a gearbox, pulley, or directly driven mechanism.
