Product Description:

The GAM2A4015V0CNK1 is a small-frame AC servo motor manufactured by Sanyo Denki and supplied as part of the G SANMOTION AC Servo Motors series. Designed for embedded axes in pick-and-place equipment, inspection stages, and light conveyor drives, the unit converts stator-fed three-phase current into controlled rotary motion under the command of a matching SANMOTION amplifier. Its feedback section delivers absolute position data to the drive, enabling closed-loop control that maintains programmed speed and torque even when the load varies.

At its continuous operating point, the motor delivers 0.15 kW of mechanical power while turning at 3000 rpm. This operating point corresponds to a steady-state shaft torque of 0.48 N·m. To produce that torque, the windings draw 1.20 Arms, and a phase resistance of 8.0 Ω keeps copper losses within the thermal capacity of the frame. Position data come from a 23-bit single-turn absolute encoder, which provides 8,388,608 discrete positions per revolution and supports tight velocity loops without external interpolation. A low rotor inertia of 0.0946 × 10⁻⁴ kg·m² supports rapid acceleration during short motion cycles.

Transient demands are handled by a drive current ceiling of 4.3 Arms, allowing the motor to reach a peak stall torque of 1.7 N·m for short intervals without demagnetization. The motor has a torque constant of 0.441 N·m/Arms, so each ampere contributes nearly half a newton-meter of torque at the shaft. An integrated holding brake rated at 24 VDC ±10% engages through a coil that draws 0.26 A, securing vertical loads when system power is removed. The circular output shaft is supplied without a key, allowing it to connect through a clamping-style coupling. An oil seal around the shaft helps limit lubricant migration into the bearing cavity while supporting protection at the output interface.
