Product Description:

The GAM2A4010F0XNK2 is a compact brushless servo motor produced by Sanyo Denki as part of the G SANMOTION AC Servo Motors series. It is intended for closed-loop positioning duties in pick-and-place stations, conveyors, and miniature indexing tables within industrial automation. The motor converts drive-side current commands into controlled shaft torque, enabling accurate speed and position regulation. Its compact square frame permits direct attachment to small gearboxes or linear carriages, while the integrated absolute feedback preserves position data after shutdown and simplifies startup routines.

During continuous operation, the motor develops 0.318 N·m of torque at a rated speed of 3000 rpm, yielding a mechanical output of 100 W. The windings accept a 200 VAC three-phase supply and have 9.0 Ω of phase resistance, permitting compact amplifiers to regulate current precisely. Mounting is provided through a 40 mm square flange that carries the pilot diameter and M3 bolt circle for rigid attachment to machinery. A keyway shaft transmits power without slipping under load. The design omits an oil seal to minimize friction in clean operating environments.

Dynamic response is aided by a rotor inertia of 0.0600 × 10⁻⁴ kg·m², enabling rapid speed changes when the drive supplies the rated current of 0.99 Arms. At this current, the electromagnetic circuit provides a torque constant of 0.367 N·m/Arms. For brief high-load conditions, the motor can produce up to 1.18 N·m of torque at stall without demagnetization. High-resolution position data come from the motor’s 23-bit single-turn absolute encoder, eliminating the need for external homing sensors. These capabilities support fine incremental moves in semiconductor handlers and laboratory automation equipment that require repeatable sub-milliradian shaft positioning.
