545 motors or 555 motors for small drills?
The proposed use of 555, the same configuration, 555 motor power than 545 motor large, but low speed, and low speed, does not affect power. 545 is worse than 555
It depends on what you drill, this motor general electric drill without heat, too, is not suitable for metal drill, and even the operating system can not be converted into a long time after the drill, I must do is intermittent operation, motor, doubt can speak.
The DC micro motor 545 and 555 are basically the same shape, 555 power a little larger, the motor shaft is shorter, used for hand-held electric drills better. 545, the motor shaft length, suitable for micro Taiwan saw.
