Why commutator are not used in ac motors?
Because, the commutator segments are used for converting AC to DC.
What is reason for armature over voltage in 450 kw dc motors?
Here we used dcon digital dc drive
Type of motor used by electric train?
dc series motors are used because of torque vs speed characteristics.
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.
How can you determine the difference between an AC or DC electric motor?
Direct current or DC electric motors work for situations where speed needs to be controlled. DC motors have a stable and continuous current. DC motors were the first and earliest motors used. They were found, however, to not be as good at producing power over long lengths. Electric companies found using DC motors to generate electric did not work because the power was lost as the electric was transmitted. Brush DC motors use rings that conduct the current and form the magnetic drive that powers the rotor. Brushless DC motors use a switch to produce the magnetic drive that powers the rotor. Direct current motors are often found in appliances around the home. Alternating current or AC electric motors are used differently based on what type of AC motor it is. Single phase AC motors are known as general purpose motors. They work well in many different situations. These AC motors work great for systems that are hard to start because they need a lot of power up front. Three phase, also called polyphase, AC motors are usually found in industrial settings. These motors also have high starting power built transmit lower levels of overall power. AC power gets its name from the fact that it alternates in power. The amount of power given off by an AC motor is determined by the amount of power needed to operate the system. garyDC motors are of mainly 3 types.series motors, shunt motors, and compound motors. DC motors are mainly used where high torque is required from less speed (rpm),and a constant rpm can be maintained.Used mainly in : lathe ,drill machines, grinding machines, compressors and so on.Ac machines have less expenses. Used widely because Ac is more popular. They have less torque on slow speeds.Used on cooling fans, water pumps etc.
Where do you find dc motors?
Examples of DC electric motors are the starter in your car and the motor in a DC controlled elevator, to name just two.
What is the best type of DC motor for use with DC?
Basically anything that works with batteries usually works with DC motors, i.g. your hard drive, your cellphone vibrator, toys, etc. Also, even for large motors, the DC motor has the advantage of being easily controlled by input voltage. Induction motors, on the other hand, can use controlled input voltage but they will have to deal wth low torque when the voltage is low. DC motors are used for those little fans in your computer. Also, CD players also use DC motors to spin the discs. DC motors are important where absolute speed control and feedback are necessary. For your household appliances, including fan motors, those are AC motors, cheaper for the industrial strength and more efficient.
Why dc series motors cannot be used in home?
DC series motors run on DC power. Homes have AC power, not DC power. You could use DC motors in homes if you have a power supply or use a battery, but it is usually more cost effective to use an AC motor.
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 is a DC motor used?
I know of fridges that have DC motors. Beyond that, I'd hate to guess.
What type of motor is used in a conveyor?
dc shunt motors
Which motor is used to drive metro rail?
DC Motors.
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 ...
Why DC motors are not used for irrigation purposes?
because dc supply is not available at house hold applications.
What type of DC motor used by fan?
DC motors are commonly used in cars and normally run on 12 v. DC motors can be broadly classified as series-wound and parallel-wound and for fans the parallel-wound version is used with the field winding placed in parallel with the armature (for domestic use AC fans using induction motors are normally used).
Which type of motor is used for traction applications?
DC series motors...
Are the fan motors on fanuc ac spindle motors ac or dc?
usually ac 110v even on the dc motors
