Micro multicopter motor high torque 820 model aircraft hollow cup motor (enhanced version of 720)

NdFeB super-strong magnetic, high-torque aircraft model hollow cup motor 820 is an enhanced type of aircraft model hollow motor 820. It is a rare treasure in the market. It is an enhanced model of aircraft model hollow cup motor 720, and its power is stronger than 720. , close to 8520

Motor diameter: 8MM

Motor length: 20MM

Output shaft: 1.0 MM

Output shaft length: red and blue line 7.5 MM,

Cord length: about 80 MM

Weight: 4g

Voltage: 3.7 V

No-load current: 0.10 A

Stall current: The red and blue lines are 4A

Speed: 43800 RPM

The operating voltage of this batch of motors should not be able to reach 4.2V, because the current

Significantly increased, its use voltage should be between 3.4V-3.7V. this is one

A very powerful hollow cup motor, it can be started at 0.2V, and the torque above 1V is OK
