What is electric braking of DC motors?
In a dc motor, when the supply is suddenly turned off, there is a suddenly fall of speed in motor. this is reduced by means of electric effect. Hence it is called electric braking ( By @FarajAlyami electric motor braking has two types 1- electromechanical 2- electrical but electrical has some types as : 1- regenerative 2- dynamice 3- plugging ( counter - current )

What is an electrical fitter?
Basically the service, maintainance and repair of many types of AC and DC motors, generators, and engine-like machinery.
What are brushes with reference to DC motors?
Bushes, with reference to DC motors is a brushed DC motor which is a motor that designed to run from a direct current (DC) power source. This type of motor is an internally committed electric motor.
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 are the different types of motors used in Broan bathroom fans?
The different types of motors used in Broan bathroom fans are typically either AC motors or DC motors. AC motors are more common and are powered by alternating current, while DC motors are powered by direct current. Both types of motors are used in Broan fans to provide efficient and reliable operation.
What are the types of induction motors?
2 types of motors First - AC Second - DC
Are DVD DC motors and DC motors same?
actually dc motors are of several types in which one of them are 1).brushed 2).brushless ...so the motor present in DVD are the brushless dc motors ...

What are the two types of dc motors?
permanent magnet motors and series motor
What is dc injection braking for ac motors and how does it work?
works with the concept of DC injection braking, where a dc volt is injected into a three phase rotating magnetic field which causes a stagnet magentic field thus bringing the motor to a complete halt.
What is the most effective braking method for ac motors?
DC injection breaking where a DC voltage is applied to the motor's coil windings.See sources and related links below.
What kinds of motors can work as generators?
Some types of dc (direct current) motor can be used to generate dc, in which case they are often called 'dynamos'. Some alternating current (ac) motors can be used to generate ac, in which case they are called 'alternators', but many types will only work as motors. For instance, a squirrel cage ac motor cannot be used as an alternator.
What is the different between ac dc motors?
DC Motor works on DC source and AC motor works on AC source
