A braking resistor is used in motion systems where a motor in controlled by a drive. Typically, these are high-speed servomotors controlled by a servodrive. When accelerating, electrical energy is converted to a mechanical force to move a mass. When decelerating, that kinetic energy is converted (via the motor) back into electrical energy, and must go somewhere. To brake quick enough, the energy must be dumped into a power resistor, to be dissipated as heat.

What happen when you remove braking resistor on the inverter?
The system will lose it's regenerative braking function, if there is no other means to stop the motor it will coast to a stop.
What are the different types of braking in dc motors?
plugging rheostatic or dynamic braking regenerative braking
Why resistor should disconnected from the circuit when measured the value of resistor?
if not disconnected you will measure the resistance of the circuit in parallel with the resistor.
What is the relation between the size of the resistor and its value?
There is no relation between the resistor's ohms value and its size. The power of the resistor can be seen by its size. If the power is too small, the resistor can be destroyed.
A 5 ohm resistor a 10 ohm resistor and a 15 ohm resistor are connected in series to a 120 volt power source. What is the amount of current flowing between the 5 ohm resistor and the 10 ohm resistor?
The current would be about 20 volts.
Why use resistor grids in DC motors?
resistor grids were used in DC MOTORS during dynamic braking. in this method of braking a resistance ( variable) is connected across armature winding so as to dissipiate the energy. the energy thus dissipiated is used for braking of motors.

What is dynamic braking used for?
Braking is used to bring the motor to stop quickly or instantly. Braking can be two way broadly. One is mechanical braking. Other method is electrical braking. One of the electrical braking is dynamic braking.
What are the types of braking used in electrical motors?
Mainly 2 types of braking are used: rheostatic braking and regenerative braking
How do you make electricity from vehicle breaking?
"Regenerative braking", or generating power from the braking motion, is often found in electric and hybrid electric cars. Essentially what is done is to "reverse" the motor leads (usually done by the computer controller) to change the motor into a generator. The generated power is then used to charge the batteries or shunted to ground through a resistor. The load of generating electricity causes the braking effect, not unlike taking your foot off the accelerator in a manual-transmission vehicle.
What is the antilock braking system?
Antiliock braking system is the mechanism which controlls the braking of brakes, If the pedals are fully pressed it will oppose the motion to protect your braking

What is braking efficiency in railway braking?

What is the definition for braking force?

Define thyristor controlled braking resistor?
A braking resistor is used in motion systems where a motor in controlled by a drive. Typically, these are high-speed servomotors controlled by a servodrive. When accelerating, electrical energy is converted to a mechanical force to move a mass. When decelerating, that kinetic energy is converted (via the motor) back into electrical energy, and must go somewhere. To brake quick enough, the energy must be dumped into a power resistor, to be dissipated as heat. A thyristor (also known as a silicon-controlled rectifier or SCR) is a diode which has a gate terminal on it. Current at the gate allows the thyristor to go into a conducting mode, allowing current to pass. Modern drives will detect when their DC bus voltage reaches a certain threshold (from the energy being returned from the motor during braking) and begin triggering the thyristor periodically (typically PWM, pulse-width modulation) to disperse this energy as heat. See links.
Is Light dependent resistor an example of resistor?
yes, a variable resistor
