ESC. (Electronic, Speed \u200b\u200bController. Or electronic speed control.) This device can be considered as the throttle servo. And we will provide voltage to the motor in proportion to throttle stick movement.
Unlike a simple servo. This has various functions such as BEC, LVC, Balance, Brake, and is built specially for the type of motor brushes, or No Brushes, and its use is limited to a certain voltage , Amps, Servos, Speed \u200b\u200bSwitching (Maximum revolutions per minute) or switching frequency. All these feature is part of the manufacturer's specifications and we must pay close attention to them.
BEC.-batery Eliminator circuit. This circuit allows us to feed the flight pack with the same battery we feed the engine. In this way we save weight occupy only a battery. Most ESC only have this feature to a maximum of 3-4 servos and a voltage not exceeding 11V. The specification is in Amperes.
There are two types of BEC. The linear, is the standard in the ESC. And the most modern and expensive are Switching BEC.
shelves, reduce the battery voltage to a level appropriate to the receiver by simple devices, they produce much heat and consume much of the available amperage.
The higher the voltage, the lower the amperage remaining for the receiver.
Using Lipo 3s battery, and more than 3 servos, it is highly recommended verify that operation of BEC. Some believe that the easiest way is to connect everything and move the sticks either way (make sure the propeller is not placed on the motor) for 5 minutes and if the BEC circuit is not super hot, and if not to off, or has gone mad, then everything is in order.
understand that this method is very rustic but it works.
quality servos consume less power and poor quality or economic consume more.
A servo Hitec HS55 consumed as WXT900 450th and consumes about 750 ma.
The switching . With this is easier, as the specification amperes of the BEC is real to any voltage to support the ESC.
So if 3A is then you can move up to 6 servos with no problems, no matter what the voltage is 3 or 4 s lipo.
not take this into account and misuse of the BEC of ESC failure can occur in the air.
Since when overheated, can get turned off by the protection circuits, and receiver voltage will manage the functions of the receiver and the servos and the plane come down.
When the ESC's BEC is not sufficient to any particular application, then use a UBEC.
UBEC, also called Voltage Regulator
This device serves two purposes.
A .- replaces the BEC. The ESC. And we provide more amps, so much servos. It connects between the battery and receiver .
Normally a BEC ESC feeds only 3 or 4 servos to 7.4V. And 11V decreases only 3 servos.
With the use of UBEC, we can feed our engine with up to 23 Volts. And be responsible for supplying the receiver with single 5V or 6V. Depending on the selection by a switch.
can supply any type of servo. Including high ampere consumption
Just a matter of pairing the ability of the UBEC to the consumption of all equipment to feed.
Two. In any system can be installed between the battery and receiver. Especially when the battery is Lipo 7.4V. O 11V. In this way we save a lot of weight and increase the capacity of the battery
has 2 connectors.
In the first 2 threads. It connects to the ESC battery connector.
Here you can put a connector, disassemble it easily.
In the second of 3 threads. It connects to the receiver.
Bec If the ESC is integrated, then the red wire going to the receiver is eliminated.
The most practical way is to remove the pin connector and insulate with termifit.
If the ESC does not have integrated Bec, then leave the cable red. Some, like the Phoenix HV ESC require that the red wire connected. And Bec have not built and occupied the voltage of% volts reached them through the receiver
's always the Red + Red
