How do you tell if a motor is brushed or brushless?
“Measure the resistance with a very low voltage (100 mV). Most DMMs will work. If the resistance is high (more than a few kilo-ohms) it is probably brushless. If it is low (less than 100 ohms) it probably has brushes. Count the wires 2 for a brushed motor and 3 for a brushless.“
