Hy. The reason for why I am here is now 2-3 days I searching on the internet web sites from where I can buy some motors. End I found a site HobbyKing. The question is : motors like this (http://www.hobbyking.com/hobbyking/stor ... 50KV.html; http://www.hobbyking.com/hobbyking/stor ... ize_.html; http://www.hobbyking.com/hobbyking/stor ... 330KV.html), can be programmed using pic, avr microcontrollers ? I ask because motors with this properties (current very high compared with current value generated by a microcontroller : 700 - 800 mA, voltage supply is bigger than voltage of a pin of a microcntroller - 5V c.c.) if they can be programmed with microcontrollers I think I need a electronic part, power transistor, Darlington, etc. Thank you.
Unfortunately your links are broken. But I'm pretty sure that basically everything in theory can be controlled by some sort of a microcontroller. If the current/voltage exceed the limits of the microcontroller itself, you need some sort of "drivers", e.g. MOSFETs. Provide us with valid links and you probably will get some help.
Sorry for mistake. The links : http://www.hobbyking.com/hobbyking/store/__364__59__Brushless_Motors-Car_Motors http://www.hobbyking.com/hobbyking/store/__23359__Turnigy_TrackStar_6_5T_Sensored_Brushless_Motor_5150KV http://www.hobbyking.com/hobbyking/store/__24426__Turnigy_TrackStar_SCT_4_5T_Sensored_Brushless_Motor_4550KV_550_size_ http://www.hobbyking.com/hobbyking/store/__21963__Turnigy_TrackStar_4_5T_Sensored_Brushless_Motor_7330KV I want to do myself an electronic driver with pic or avr microcontroller. I know, maybe you said that is very dificult and honest it is, specially when you dont have an electrical drawings. I sure that I need some MOSFETs. Thank you for your interest.
You should read and learn about the basic operation of brushless DC Motors. And yes, you will need some badass MOSFETs.
You need an "ESC". http://www.hobbyking.com/hobbyking/store/__455__182__ESC_UBEC_VR-Above_80_Amp.html You can control them with your avr/pic.
That would be the easiest Solution. The ESC is controlled like a normal servo ( 1ms to 2ms pulses, just google it)
