Product Description:

The GAM2A4005F0CNK0 is a small-frame servo motor produced by Sanyo Denki within the G SANMOTION AC Servo Motors series. The model supplies precise, low-power rotary motion with tight position control and fast cycle times. It is suitable for automated pick-and-place heads, indexing tables, and small conveyor axes that require responsive movement within a compact installation.

This motor delivers a continuous stall torque of 0.167 N·m, allowing it to hold loads without overheating when the shaft is locked. During short transients, the drive may command up to 2.9 A RMS of phase current, giving the motor reserve torque for acceleration or disturbance rejection. The rated mechanical output is 0.05 kW at a nominal shaft speed of 3000 rpm. These values establish the continuous operating point used when sizing gear stages or selecting belt ratios. A winding phase resistance of 9.3 Ω affects resistive losses and the voltage that the amplifier must provide at the rated current.

Additional performance limits include a peak stall torque of 0.59 N·m, which is the maximum static torque available from the rotor without shaft movement. Continuous operation draws a rated armature current of 0.79 A RMS, so amplifier thermal requirements can be based on this steady value rather than the higher short-term current. The motor has a torque constant of 0.235 N·m/A RMS, providing a direct conversion between commanded current and produced torque. Dynamic response is supported by a low rotor inertia of 0.0394 × 10⁻⁴ kg·m², permitting rapid speed changes while keeping drive gains moderate. The rated power rate is 6.4 kW/s, and a single-turn absolute encoder supplies position feedback. The shaft has no keyway or oil seal, which supports clamping-coupling installation in dry, clean environments and reduces friction at the shaft interface.
