Product Description:
The GAM2A4005F0CRK3 servo motor is produced by Sanyo Denki for the G SANMOTION AC Servo Motors series. This low-power rotary unit is intended to drive compact axes in pick-and-place heads, small conveyors, or laboratory automation where precise velocity and position control are required. By converting electrical commands from a compatible drive into controlled mechanical torque, the motor provides controlled motion for industrial machinery. Its compact design also makes it suitable for equipment with limited installation space or low moving-mass requirements.
At its rated operating point, the motor delivers 50 W while producing 0.159 N·m at 3000 rpm. The drive supplies 0.79 Arms to windings that measure 9.3 Ω per phase. The electromagnetic circuit provides a 0.235 N·m/Arms torque constant, which establishes the relationship between current and torque for control calculations. Continuous stall torque is 0.167 N·m, allowing the shaft to hold a static load without overheating when the motor operates within its permitted thermal limits. These electrical characteristics allow a compatible servo drive to regulate torque accurately during positioning, holding, and low-speed operation.
When an application requires greater transient torque, the motor can withstand a 0.59 N·m peak stall load, and speed commands can reach 6500 rpm for short periods. Position feedback is delivered by a 23-bit absolute encoder, providing high resolution for fine indexing tasks and precise closed-loop control. The motor has a 40 mm square flange, an overall length of 93 mm, and a mass of 0.48 kg, allowing installation on lightweight axes without adding excessive moving mass. Its 8 mm shaft projects 12 mm beyond the faceplate and provides a compact mechanical interface for couplings or other driven components. The internal rotor inertia is 0.0394 × 10⁻⁴ kg·m², supporting rapid acceleration, deceleration, and direction changes with limited overshoot.
