Hi guys
Has anyone ever tried powering their tamiya motors via usb? Like a powerbank or something? Can be done n will spin fast? Will the motor burn? I need to make a really really really strong suction fan powered by usb powerbank n i can only think of tamiya motors...but they r rated at 3v Cant seem to find much 5v motors out there |

QUOTE(advocado @ Aug 28 2017, 03:10 PM) how big is the fan. you understand those motor are tiny? to run a big fan efficiently the motor will have to rev really high. also the motor is not designed to drive heavy objects. i think the spec has their maximum load. size off fan blades yet to be determined... this is gonna be a DIY project.. so i might end up making the blades out of aluminium soda cans to keep the weight down...or ill use the fan blades from a 12cm or 8cm...dependingyes i know they are tiny.. but they are the only motors i can think of that require low voltage but spins really fast. im just worried that the 5v will burn them |

QUOTE(advocado @ Aug 28 2017, 04:22 PM) to connect the motor to a USB you would need some wiring, so you just need to add some resistor to bring the voltage down from 5V to 3V. wiring i have...good idea about the resistor thing.. will look into that.still wondering about direct connection though |
