I've got a question about dc motors. I see posts about rewinding them with more wire to change the output voltage. The motor i have has 4 brushes in it but they are not at 90 deg. from each other. This motor is rated 13 amp. 24 vdc @ 194 rpm . I wonder how it could run at such a low rpm. So i had to look inside it looks like about 14ga. wire and has 37 poles and from looking 20-30 turns of wire. Ok what i dont understand is the brush setup. the 2 brushes that the power goes in on are at about 120deg. apart, the other 2 are about 120deg. from them and about and inch apart and both are hooked to ecah other. I will try and add a photo that may help show what I am talking about . My thinking is this was done to get such low rpm but i don't understand how they did it. If so this might be done on other motors to change the rpm. When i tested this motor hooked to a 12v battery I got 5amps. at @150 rpm and over 100 open volts at about @1200 rpms I would like to use this but i need lots of power and low rpms and could use some help with blades also. Thanks!
