Where did you find the Model for the 3D-printed motor ? XD
07:47
<
buZz >
guso78k21: you could, sure
07:48
<
buZz >
there's many BLDCs you could print nowadays
07:48
<
othx >
buZz linked to "BLDC simple motor by emartinelli" on thingiverse => 1 IRC mentions
07:49
<
buZz >
they arent as efficient as cheap chinese motors though
07:49
<
buZz >
also they weigh more
07:52
<
guso78k21 >
.. excited ...
07:56
<
J23k42 >
wait when they get hot ..
08:04
<
buZz >
J23k42: yeah, because PLA is the only thermoplast that exists ;)
08:05
<
guso78k21 >
i am wondering if nowadays bldc controllers can slow accellerate their speed, know its load, and realize if they get stuck for any reason to accellerate again
08:06
<
buZz >
guso78k21: yes they can
08:06
<
buZz >
guso78k21: in fact, since bldc controllers (aka ESC) exist
08:06
<
buZz >
the type you get for that are 'sensored' ESCs
08:06
<
guso78k21 >
i think such ESC sit in my quadcopter :')
08:06
<
buZz >
and you add hall effect sensors on the stator, to detect position of the rotor
08:07
<
buZz >
likely not, quadcopters are aiming for low weight
08:07
<
buZz >
plus they arent really needed below ~100rpm
08:07
<
buZz >
eh, ABOVE ~100rpm
08:08
<
buZz >
either way, practically ALL ebike ESCs i've ever seen use -sensored- motors
08:10
<
buZz >
btw, its not 'speed' they measure, but 'phase'
08:10
<
buZz >
as BLDC motors are triple phase AC ;)
08:11
<
guso78k21 >
is there a a virtual ground wire used ?
08:11
<
buZz >
no, its a actual ground wire used
08:12
<
buZz >
oh actually, only for the sensors, the three phases dont get any GND , their circuit is just between the three phases
08:13
<
buZz >
sensorless BLDC have -just- 3 wires
08:13
<
buZz >
sensored ones usually 3 thick ones and seperate header with 4? wires
