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 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 Purpose of electrical symbol?
Electrical symbols are used in electrical wiring diagram, signage on the electrical devices and 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.
Where do you use sequence starting methods for electrical motors?
it is used in conveyors belts.
What are the two types of bearings used in motors?
ball type
What are two types motors used for hermetic compressors?
Rotary and Induction
Does Smith Motors make car or air-conditioning motors?
The A.O. Smith company is a top supplier of electrical products for automobiles. They manufacture hermetic motors for air conditioning that are used in automobiles.
Where is iron used for conducting?
Iron is commonly used for conducting electricity in electrical transmissions systems, particularly in power lines and transformers. It is also used in the production of electrical motors and generators.
How cable ware types of motor?
Cable types for motors typically refer to the various electrical cables used to connect motors to power sources and control systems. Common types include power cables, which deliver electrical energy to the motor, and control cables, which transmit signals for operation and feedback. Additionally, shielded cables may be used to protect against electromagnetic interference, while flexible cables are ideal for applications with frequent movement. Proper selection of cable type ensures efficiency, safety, and reliability in motor operation.
