Many kinds of manufacturing or processing operations use heavy equipment powered by motors like the Reliance DC motor SC2512ATZ. This is a fine motor which is known for its dependability. This type of motor uses brushes and a commutator, but some direct current motors no longer require brushes. Here is a look at both brushless and brushed models to aid you in your selection.
A powerful Reliance DC motor SC2512ATZ uses both permanent and electromagnets to rotate. One set of magnets is located in the stator while the other is in the rotor. Both stator and rotor cannot be permanent magnets because the polarities must change for rotation to occur. The rotor windings are connected to the source of power. However, since it is constantly turning, there is no way you can make a direct connection like attaching wires to a terminal.
The Reliance DC motor SC2512ATZ gets its power from a set of brushes attached to the power source. The brushes are in contact with a segmented rotating conductor called a commutator. This allows for a constant flow of electricity with a spinning or rotating part. Bushed motors have been around for a long time, but there is another option.
Brushless Motors
A brushless DC motor relies on a part called a Hall sensor. It uses electromagnetic sensing to detect the position of the rotor. Instead of transmitting power to the motor via a commutator and brushes, these motors get power from oscillators.
Which One to Choose?
Brushless DC motors have few maintenance concerns. There are no brushes or commentators to wear out or replace, and they dissipate heat better to run cooler. Yet, brushed motors are still used because they work well for low-end industrial applications. Many brushed motors have easy access to brushes, so changing them is not time-consuming or expensive.
