What makes up a Brushed R/C Electric Motor.A Closer look at the Parts that makeup a R/C Brushed Electric Motor.
To better understand a brushed r/c electric motor we need to take a closer look at each of the parts. We will look at each of the parts and go into as much explanation as needed for each part. 
Let start off with the heart of a r/c electric motor the armature. Plus, it can be the most confusing part of the r/c electric motor. What confuses many people are how a electric motor is rated, by it's turns or winds. The Number of Turns Is the number of times the copper wire is wound around each pole of the armature. More Turns = Less RPM, higher torque, longer battery life and slower speeds. Higher Turns = Higher RPM, less torque, shorter battery life and higher speeds. The Number of Winds Is the number of wires that are wound around the armature. Single Wind = Higher bottom end power. Power is achieved at lower RPMs. Better for short race tracks with a high number of turns. Double - Triple - Quad Winds = Less bottom end power. Power is achieved at higher RPMs. Better for long race tracks with long straight aways. 
This is an inside look at the end bell. You can see the bearing at the center of the end bell. Along with the ends of the brushes. You can see the bearing, the brush hood and brushes. 
A closer look at the brush and brush spring. The brush is what makes contact with the commutator. The spring keeps tension on the brush so it will not lose contact with the commutator. 
The brush hood is what holds the brushes in place and at the correct angle. 
The bearing, at each end of the can, is what supports the armature. 
This is a closer look at the commutator (comm) of the armature. The comm can also vary in size. A bigger comm is for high load, high current applications. Off-road racing. A smaller comm is for higher RPMs, lower current applications. On-road racing. 
One other thing to keep in mind is the method that your r/c electric motor is wound, by hand or machine. Hand wound is more precise, giving you more power and is more expensive. Machine wound is less precise, giving you less power and is less expensive. We hope this closer look at the parts of a r/c electric motor has given you a better understanding to how and why the R/C Electirc Motor works. check out the Rc Truck n Car Tuning swicki at eurekster.com Return to Introduction to the RC Electric Motor
