I remember there was a thread about what the numbers mean regarding a 540 size motor. Anyways, I found this on the Mabuchi motor website and I thought y'all would find this interesting.
Motor Designation and Meaning
Example: RS-540S
The first letter stands for the motor housing shape
R = Round
F = Flat
S = Square
EG = Electronic Governor Motor
CO = Synchronous Motor
The second letter stands for the brush construction
E,A,U = Metal brushes
F,D = Precious Metal brushes
C,K,H,S,T = carbon brushes
The first number stands for the armature diameter code number
Unfortunately, there are no descriptions of the codes. :(
The second number stands for magnet size or housing length
The third number stands for number of armature poles
0 = 3 pole
4 = 4 pole
5 = 5 pole
6 = 6 pole
8 = 8 pole
On the second set of letters, the first one stands for the type of magnet
R = C-shape isotropic magnet
T,Y = Ring shape isotropic magnet
S,P,V = Anisotropic magnet
C = Rubber magnet
W = Neodymium magnet
The second letter (if any) stands for the motor variation.
So an RS540S motor would have a round type motor housing, carbon brushes, a code 5 for armature size, size 5 magnets or 5 "whatevers" long, 3 poles and anisotropic magnets.
There are also 4-5 additional numbers at the end that tell the diameter of magnet wire :confused: and number of turns on the armature. Unfortunately, our example doesn't carry those extra digits.
