Introduction To Electronic Speed Control (ESC) Working and Applications

Introduction To Electronic Speed Control (ESC) Working and Applications ESC stands for an electronic speed control is an electronic circuit used to change the speed of an electric motor. These are frequently used on radio controlled models which are electrically powered, with the change most frequently used for brushless motors basically providing an electronically produced 3-phase electric power low voltage source of energy for the motor. An ESC can be a separate unit which lumps into the throttle receiver control channel or united into the receiver itself, as is the situation in most toy-grade R/C vehicles. http://www.elprocus.com/

Introduction To Electronic Speed Control (ESC) Working and Applications Features of an Electronic Speed Control An ESC controls the speed of the motors spin of an airplane. It helps the similar purpose as the throttle servo of a glow powered airplane.  It is an edge between the radio receiver of an airplane and the power plant.  An electronic speed control will have 3- sets of wires. http://www.elprocus.com/

Introduction To Electronic Speed Control (ESC) Working and Applications Types of an Electronic Speed Controller There is two kinds of electronic speed controller based on the specific requirements. It can acquire the exact one existing in RC Models shops such as Brushed Electronic Speed Control Brushless Electronic Speed Control http://www.elprocus.com/

Introduction To Electronic Speed Control (ESC) Working and Applications Types of an Electronic Speed Controller Brushed Electronic Speed Control: Brushed ESC is the first electronic speed controller, which has been around for several years. It is very cheap to use in various RTR electric RC vehicles. http://www.elprocus.com/

Introduction To Electronic Speed Control (ESC) Working and Applications Types of an Electronic Speed Controller Brushless Electronic Speed Control: Brushless ESC is the modern advancement in technology once it comes to Electronic Speed Controls. It is also a bit more costly.  Connected to a brushless motor, it carries more power higher performance as compared to the brushed ones.  It can also last a longer period of time. http://www.elprocus.com/

Introduction To Electronic Speed Control (ESC) Working and Applications Electronic Speed Controller Circuit The term ESC is frequently used as a contraction for ‘electronic speed controller.  The basic function of ESC is to change the amount of power to the electric motor. From the aircraft battery based upon the location of the throttle stick. In earlier, speed controllers are mainly used in remote control boats and cars which use a variable resistor with a wiper that was stimulated by a servo motor. http://www.elprocus.com/

Introduction To Electronic Speed Control (ESC) Working and Applications Electronic Speed Controller Circuit This technique works reasonably at full throttle as the battery is associated straight to the motor. Though at part throttle situations the flow of current through the resistor producing power to be lost in the form of heat. As a model, aircraft will use most of its time at the portion of the throttle. This is not a very practical means of power control. Current speed controllers differ the power to the motor by fast switching the power ON and OFF. http://www.elprocus.com/

Introduction To Electronic Speed Control (ESC) Working and Applications Electronic Speed Controller Circuit MOSFET Transistor is used as a switch instead of a mechanical device, and the amount at which it is switched is about 2000 times a second. So, the power to the motor is diverse by changing the amount of ON time, against off time in a specified cycle. Here is the simple ESC circuit with waveform diagram may help with the description. MOSFET is switched ON, when current rises up as the magnetic field in the windings of the motor increases. http://www.elprocus.com/

Introduction To Electronic Speed Control (ESC) Working and Applications Electronic Speed Controller Circuit When MOSFET is switched OFF, magnetic energy stored in the windings has to be absorbed by the ESC. By cabling a diode across the motor, we return the energy back into the motor as current, which rises down as the magnetic field failures. http://www.elprocus.com/

Introduction To Electronic Speed Control (ESC) Working and Applications Choosing the Right ESC The number one significant consideration to keep in mind is to match the Electronic Speed Control to the sort of motor you used.  Be sure to purchase the correct ESC for the exact motor. Brushed ESC is used for the brushed motor, brushless ESC is used for the brushless motor, never vice versa. Usually, apart from the labels, you will directly know that it’s a brushed motor if it has 2-wires. If the motor has three wires, then it is brushless. http://www.elprocus.com/

Introduction To Electronic Speed Control (ESC) Working and Applications Choosing the Right ESC For people who are not aware with electronic speed control, most of the models like RTR RC model are provided with a pre-installed Electronic Speed Control. Most of these are brushed digital units that carry a decent act in their operations. If RC car comes with an analogue speed control, which needs a servo in order to work the swing arm, consider receiving a digital one as soon as you can. This way you will remove all the disturbances and preventions going down from the area of the driver’s stand to recover your RC car every time it becomes stuck in the track. http://www.elprocus.com/

Introduction To Electronic Speed Control (ESC) Working and Applications Applications of ESC The electronic speed control systems are used in remote control and vehicle applications Electric cars Electric bicycles Electric aircraft Cars Helicopters Airplanes Boats Quadcopters ESC Firmware http://www.elprocus.com/

Introduction To Electronic Speed Control (ESC) Working and Applications Conclusion Electronic Speed Control  is an electronic circuit with the purpose to vary an electric motor's speed, its direction and possibly also to act as a dynamic brake. ESCs are often used on electrically powered radio controlled models, with the variety most often used for brushless motors essentially providing an electronically generated three-phase electric power low voltage source of energy for the motor. http://www.elprocus.com/
