to mark as completed help me in my quadcopter
hello
my project is small quadcopter using 8 small coreless motors without ESC
motors http://www.ebay.com/itm/251743556401?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT
Voltage: 3.7 V
Current: the empty set: 0.08 A
Stalling: 1.8 A
Speed: 52000 RPM (the actual speed may be high or low)
Voltage: 4.2 V
Current: the empty set: 0.1 A
Stalling: 2 A
Speed: 60000 RPM (actual speed may be high or low)
motor driver TB6612FNG pololu dual motor driver https://www.pololu.com/product/713/specs
| Continuous output current per channel: | 1 A |
|---|---|
| Peak output current per channel: | 3 A |
| Continuous paralleled output current: | 2 A |
| Maximum PWM frequency: | 100 kHz |
arduino nano v3
battery 3.7 v 1000mah (motor power)
I made a test to know what max current can out from TB6612FNG(thoricly 2 amp) ,
I did that by changing PWM from 0 to 255 ,
I was expect that the current requested from motor should be 2 amp (max current) when the PWM in 255
- but I found in my multimeter only 0.4 amp !!!! why
- is the frequency of PWM can change the current out ?
