Electronic Speed Controllers (ESC)

The name of the device, which is the heart of the engine, is Esc (Electronic Speed ​​controller.), found in all electric powered unmanned vehicles, frequently used by people dealing with Radio Controlled electric aircraft. Electronic speed controller is an electronic circuit board that controls the speed of a brushed or brushless electric motor and regulates the current coming from the battery, as well as allowing the motor to reverse and dynamically brake.

What is ESC and
What Are Its Usage Areas?

Electronic speed controller is an electronic circuit board that controls the speed of a brushed or brushless electric motor and regulates the current coming from the battery, as well as allowing the motor to reverse and dynamically brake.

ESC Usage Areas

It is used in remote control and vehicle applications.

What are the Esc Types?

Brushed Esc

It uses the on-off method in voltage to determine the speed of the motor. The on-off method is done many times within seconds. To slow down the speed of the motor, the incoming voltage is turned off for a long time, and vice versa to increase the speed.

Brushless ESC

It is a little more costly than a brushed esc. When connected to a brushless motor, it carries more power and higher performance than those with brushed escs. It can be exposed to high instantaneous values ​​for a longer period of time.

What is the Basic Working Principle of Brushed and Brushless Escs?

Finely adjusts motor direction and speed via FET (Field Effect Transistors) transistors in brushed and brushless escsnnThe new technology uses BEC (Battery Eliminator Circuit) to generate stable voltage between the battery, motor and receiver of many ESC models.

What is BEC?

Many ESCs have BEC feature. The BEC feature is a very important feature. BEC linearly reduces the voltage from the battery to supply the control receiver (reduces it to 5 or 6 volts). Brushed and brushless vehicles require a high voltage value in their motors. High voltage value is supplied to the receiver. It is very important to use BEC indirectly because of the damage it may cause. When converting high voltage to voltage suitable for the receiver, heat is generated.

For example,

In the aircraft we use, the battery needs 11.1 volts and the receiver needs 5 volts. In such a case, 11.1-5= 6.1 Volts is converted into heat, preventing damage to the receiver.

What is Flashing Esc and What are Esc Softwares?

There are many firmwares available for Escler and many of us don't care much about the software included in esc when they first start projects about Model airplanes, multicopters, drones, but Esc software is very important for the user.

What are the esc software in this article? What are their importance to the user?

Esc programming is called flashing many resources esc. Increasing or decreasing the throttle sensitivity transmitted by the control to the receiver, starting power, esc temperature protection, motor direction (it can rotate bidirectionally if desired (We have sample video below), demag compensation, motor timining, beacon length, up to the length of the beep sound coming from Esc. You can set the unique properties of esc.

What is Flashing to Esc?

Esc flashing is done manually with Esc flash device or arduino. One of the most important devices required for this process is the computer. The connection end of the Esc flash device or the device made with arduino is touched on the processor in the esc and the process takes place.
