Introduction To Electronic Speed Control (ESC)
Working and Applications
Introduction
  • 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.

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.

Features of an Electronic Speed Control
  • One wire will plug into the main battery of an
    airplane. 
  • The second wire will have a typical servo wire
    that plugs into the receivers throttle
    channel. nd lastly, a third of wire is used for
    powering the motor. 
  • The main features of an electronic speed control
    include battery eliminator circuit, low voltage
    cutoff, brake, and to.

  • The components used in ESC mainly include the
    following
  • Solder pads for the 3-BLDC motor phases
  • Negative (-) LIPO connections
  • Positive () LIPO Connection
  • Servo signal or input of the PWM signal

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

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.

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.

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.

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.

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.

  • 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.

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 its a brushed motor if it has 2-wires.
  • If the motor has three wires, then it is
    brushless.

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
    drivers stand to recover your RC car every time
    it becomes stuck in the track.

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.
