RE: How does a brushless motor work?

Yes, the timing of the electrical pulses that are sent to the motor determines the direction of rotation. Most airplane brushless speed controls can only drive a motor in one direction. You reverse...

RE: How does a brushless motor work?

It's an ELECTRIC motor :)

BTW, the AC vs. DC argument took place earlier in this thread.

RE: How does a brushless motor work?

That is how it was explained to me by a person that builds brushless ESCs for a living. I made the mistake of calling it "three phase AC" one too many times, and was sternly reprimanded...

RE: How does a brushless motor work?

The numbers are essentially meaningless. They tell you nothing about how the motor performs, nothing about what the motor would be useful for. In most cases, the numbers are the motor's dimensions....

RE: How does a brushless motor work?

A popular myth that I fell victim to myself. Turns out that even though the ESC does switch the polarity back and forth on the various phases of the motor to make it turn, it's still putting out DC...

RE: How does a brushless motor work?

A brushless motor is "inside out" compared to your GWS motor. The windings are glued to the inside of the can, and the permanent magnets are bonded to the rotor. Since the wires don't move, you don't...
