4112 Brushless Motor
The Atlas 4112 is a 450 KV brushless motor with a 4S–8S supply range and a peak current rating of 60 A for 10 seconds in still air. Its 41 mm stator has a 12 mm stack height, and the motor draws 0.6 A at 10 V under no-load conditions.
Weighing 148 g, the 4112 measures 46.50 mm in diameter and 28.80 mm high excluding the propeller shaft. It incorporates a 3.95 mm diameter shaft stud extending 5 mm above the motor, together with four M3 mounting holes at 25 mm spacing.
The motors are supplied in packs of four, with volume orders available directly from Atlas.
