ESC has different meanings in different sectors. The most common areas of use include cars and remote control vehicles. In cars, ESC means electronic stability control, while in remote control vehicles, RC cars, airplanes, boats, UAVs, drones and RC helicopters, it means electronic speed control.
What is ESC for Cars?
Electronic stability control is a system used to control the stability of the vehicle and provide improved driving safety. This system usually provides a better driving experience on slippery roads or in difficult conditions.
Electronic Stability Control (ESP), also known as Electronic Stability Program (ESP) or Dynamic Stability Control (DSC), is a computerized technology that detects and reduces loss of traction in order to increase vehicle stability. When ESC detects a loss of steering control, it automatically applies the brakes to help the driver steer in the desired direction. Braking is applied individually to the outside rear wheels to prevent oversteer, or to the inside rear wheels to prevent understeer.
Some ESC systems also reduce engine power until control is regained. ESC does not improve a vehicle's cornering performance, but it does help reduce the likelihood that the driver will lose control of the vehicle.
According to the U.S. National Highway Traffic Safety Administration and the Insurance Institute for Highway Safety, one-third of fatal crashes between 2004 and 2006 could have been prevented using technology. In Europe, electronic stability programs have saved an estimated 15,000 lives. ESC has been mandatory in new cars in Canada, the U.S. and the European Union since 2011, 2012 and 2014. Worldwide, 82 percent of all new passenger cars have anti-skid systems.
What does ESC stand for for remote control vehicles?
Types of ESCs
1. With and without brushes
Brushed and brushless motor base can be divided into two, usually according to the control signal to adjust the speed. The connections are usually made as follows:
ESC input line connected to battery;
The ESC line is connected to the motor; two lines are used in brushed motors and three lines are used in brushless motors.
ESC signal lines connected to the receiver.
What is the difference between brushless and brushed ESC?
Brushless motor and brushed motor are similar to the hub and switch in the computer network. Brushed motor is a typical motor powered by direct current or voltage (We only focus on the DC field, no AC motor).
2. Different types of software: Blheli, Simonk and Kiss
The ESC program is open source and based on open source. There are 3 different firmware that you can use on your ESC, which can be divided into blheli, simonk and customizable firmware.
3. BEC and UBEC
When the term Battery Elimination Circuit (BEC) is used, it usually means that ESCs with BECs can output a specific voltage, thus powering your receiver, servos or flight controller. A UBEC is usually described as a switch mode unit that can step down the voltage from 4s+ packs to ~5v and supply up to 10A.
What is RC ESC? What is BEC/UBEC? What does BEC/UBEC do?
ESC (Electronic Speed Control) is a speed control circuit used to control the speed of electric motors. It is often used in remote control model vehicles and is part of the hardware of vehicles such as model airplanes, cars, boats, helicopters and drones. Without ESC, it is not possible to control the speed of the motor and the motors cannot be connected directly to the receiver.
Brushless motors require a brushless ESC, and brushed motors require a brushed ESC.
What is BEC/UBEC, one of the features of ESCs, and what does it do?
ESCs usually have BEC or UBEC features. BEC (Battery Eliminator Circuit) and UBEC (Universal Battery Eliminator Circuit); These two features have the same function. These are voltage reducer circuits. However, their working principles are different. BEC circuits are linear voltage reducers. They are less costly, but their efficiency is slightly lower. UBEC circuits are switched (Switchmode) voltage reducers.
UBEC circuits are more efficient, produce less heat, but cost more. Whether an ESC has a BEC or UBEC is not related to its ability to control motor speed and does not determine the quality of the ESC, because the motor speed control feature is independent of the BEC/UBEC function.
BEC and UBEC basically do the same thing. They reduce the voltage of the battery connected to the ESC to the voltage required for the receiver and servos to operate. Generally, the receiver and servos support an operating voltage in the 5-6V range. Some receivers and servos are compatible with up to 8.4V. l
However, most often the ESC's BEC/UBEC circuits provide 5 or 5.5V output.
Although there are some exceptions, ESCs with adjustable BEC/UBEC are generally produced up to 8.4V.
If the ESC does not have BEC/UBEC (such as Opto ESCs for drones), the system will draw power from an external power source for the receiver and servos. This external power source can be a standalone BEC/UBEC circuit or a battery with the appropriate voltage.
What is ESC for RC Cars?
Although RC vehicles have similar parts to real cars, the only major difference is the ESC.
If you are new to the hobby, you may be wondering what ESC is and what it does for your RC car.
Electronic speed controller (ESC) is an electronic circuit that controls the speed of a vehicle. ESC manages the speed and brakes of RC vehicles, allowing the user to fully control the vehicle's performance.
How does ESC work?
ESCs receive signals to determine the speed and direction desired by the user and use these signals to control the speed of the motor. The ESC provides or cuts power to increase or decrease the speed of the motor, thus managing the speed of your RC car. This is especially important for racing and other high-performance applications.
ESCs also have a braking function. When the user gives the brake command, the ESC applies feedback to slow or stop the motor.
Ultimately, an ESC gives you full control of your RC car's speed and brakes.
