00:00.000 --> 00:07.983
Hybrid stepper motor with permanent magnet rotor

00:07.983 --> 00:18.059
Connected to the oscilloscope, we will check its reversibility: becomes generator?

00:18.059 --> 00:36.288
A neutral motor connected to the ground of the oscillo, 2 coils to the red and blue inputs

00:36.288 --> 00:49.811
2 coils in series therefore opposite to 180 ° as evidenced by the curves

00:49.811 --> 01:09.948
Frequency, inversely the period, and amplitude also depending on the speed

01:09.948 --> 01:22.624
We will connect a coil offset by 90 °

01:22.624 --> 01:35.415
The phase shift is now 90 ° and not 180 °

01:35.415 --> 01:50.813
180 ° again and last combination ...

01:50.813 --> 02:00.875
That's 270 ° or -90 ° ...

02:00.875 --> 02:12.678
All brushless motors step by step (without electronics) are reversible as generator

02:12.678 --> 02:29.615
On the other hand, we generate an alternating current! Without mechanical rectification (continuous motor)

02:29.615 --> 02:42.790
Electric cars also use disc engines, parallel coils

02:42.790 --> 02:51.308
These motors are very easily reversible as a generator for charging

02:51.308 --> 03:06.904
To confirm: the fan is reversible BUT by removing its electronic timer

03:06.904 --> 03:19.767
Like on cars, a brushless motor straightened in this lamp!
