Inventory of brand new original high-power 4825 high-speed neodymium strong magnetic brushless motor, with a nominal voltage of 21V and a maximum power of approximately 600W. Originally designed for use with 10 inch electric chain saws, the motor is suitable for retrofitting power tools or model drive motors, etc.

The motor is mounted on an 18V/21V lithium battery garden machinery tool, with a 26mm diameter neodymium strong magnetic inner rotor and strong magnetic force. Four neodymium magnets are embedded inside the rotor, which drives balance correction. The front and rear ball bearings are equipped with built-in cooling blades, and the stator diameter is 48mm with a thickness of 25mm. The three-phase output lead is 16AWG silicone wire with a length of 20cm.

The motor has a nominal voltage of 21V and a maximum power of approximately 600 watts. The motor can also be operated using a model airplane brushless electric controller or a high-speed Hall free brushless controller. The actual measured no-load speed of the motor using a brushless electric controller at different voltages is as follows:

12V voltage test, no-load current 2A, no-load speed 13000 revolutions per minute.

18V voltage test, no-load current 2.8A, no-load speed 19500 revolutions per minute.

21V voltage test, no-load current 3.1A, no-load speed 22600 revolutions per minute.

The motor weighs approximately 330 grams.
