Buy a combination of products,
You can generate electricity when you get it.
775 motor tail connected to the 12V battery or other power supply, you can generate electricity.
New inner rotor three-phase brushless DC motor,
DC 230V (230V after AC220V rectification and filtering),
It's a brushless motor with a vaneless fan,
DIY becomes a brushless generator.
Note: if you want to use as a brushless motor, to drive the board, can not be directly connected to the AC.
Motor diameter: 43 mm
Motor height: 60.5 mm
Output shaft: 5 mm
Output shaft length: 30.2 mm (with a small thread at the end)
Motor lead: three wire (three phase brushless DC motor with Hall)
Wire length: 630mm
Motor weight: 308G
The magnetism of the rotor is very good,
However, due to the brushless motor and double ball bearing,
Therefore, the shaft rotation of the motor is lighter than that of the brush motor, which is suitable for DIY to be a generator.
We measured several groups of generating voltages at different speeds
900 RPM: 22 V;
1150 RPM: 29 V;
2380 RPM: 60 V;
4600 RPM: 124v;
6170 RPM: 158 V;
9950 RPM: 261 v
be careful:
1. The power generation voltage depends on the rotational speed, with high speed, high voltage, low speed and low voltage.
2. Generating power is within 40W,
Suitable for non-polar and non inductive circuits,
For example, incandescent lamp, fluorescent lamp, energy saving lamp, led, etc.
3. Limited power, not suitable for refrigerators, air conditioners, washing machines, rice cookers, etc.
4. The motor is high voltage and low current,
It is not suitable for 12V or 24V low voltage and high current electrical appliances, because the current can not reach.
