What is a short -crumb engine?

The brush engine is an electric motor powered by a direct current (DC). Although more expensive than a standard electric or brushed engine, it has considerable advantages over its predecessor. Most remarkably, the eye -free engine boasts better power and suffers from less wear than brushed engines of a similar size.

In order to understand the benefits of a short -crumb engine, a basic understanding of the brushed engine is required. In the brushed engine, an electromagnet, called fittings or rotor, is mounted on the spinning arm. The adaturate sits between two magnets set in the horseshoe configuration, together called Stator. When the power supply is powered into an electromagnet, the shoulder moves and aligns the North and South poles of the electromagnet with the enemy poles of the Stator. In order to turn the engine, the electric current direction must be switched. Changing the current rolling of Electromagnet poles, causing the fitting to continue its rotation until it satisfies the stator. Polarity must change quickly there and ZPto make a constant rotation. When the fitting spins, brushes alternately connect with the contact point on the axle. This contact point is connected to the energy source. By turning the brushes around the contact point, the current rapidly changes the direction and switches the polarity of the solenoid.

brushed engines are cheap for production, but have their limitations. The brushes wear the contact point and axle from the shock. The friction from this contact also prevents performance.

Lookless engine turns this design inside. The magnets are located on an anchorage and are surrounded by one or more electromagnets. The current switch to the computer, switch off the electromagnets by switching off and turning on the current; The computer can also take into account the current engine speed to optimize efficiency, everything without the need for brushes.

It all causes a short -crumb engine to be significantly more powerful than brushed engines of a similar size. Non -backThe engines have excellent control, accuracy and efficiency; Also, bead engines are quieter. In larger models where it can be overheated, it is easier to cool and there are no brushes that can wear out.

The 6 brush engine is also popular among racing enthusiasts of remote control (RC). However, the engines are much more expensive than brushed engines and tend to be used only where the advantage outweighs.
