In Ice factories it is most preferred!!!
it demagnetizes severely when field polarities are reversed.
but when connected properly ,can be used for ample applications.

Can be motor used on both ac and DC is?
this is called a universal motor most non wireless hand tools have universal motors these are series dc motors with laminated poles they can tolerate ac but run better on dc
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.
What are industrial applications of DC shunt motors?
Dc shunt motor is a constant flux and constant speed motor . So that it is used in centrifugal pumps ,machine tools ,blowers and fans etc.
Why DC motors and DC generators are commonly known as DC machines?
because the dc motor will act as dc generator as same as dc generator acts as a dc motor .so it is called as dc machines.AnswerBecause generators and motors are machines, and operate on d.c.'A.C. machines' are generators, transformers, and motors which operate on a.c.
who is more efficient dc motor or ac motor and why?
DC motors are generally more efficient than AC motors. DC motors have a lower amount of inertial associated with them, making them more efficient to run.
What are the advanced applications of DC series motors?
what are the advanced applications of dc series motor
Which type of motor is used for traction applications?
DC series motors...
Does DC motor run at a varying speed?
only shunt dc motors have varaible speed control. compound dc motors do however NT as much, plus they are just a mixture of series and shunt dc motors.
Why DC motors are not used for irrigation purposes?
because dc supply is not available at house hold applications.
What are the different types of dc motors give their applications?
Different Types Of DC Motors With Their Applications:Type 1: DC Shunt Motor:Applications Of DC Shunt Motor:Reciprocating pumpCentrifugal pumpMachine ToolsBlower and FanLatheConstant speed line shaft, etc...Type 2: DC Series Motor:Applications Of DC Series Motor:Electric TractionTrolley CarCrane, HoistConveyor, etc...Type 3: DC Cumulative Compound Motor:Applications Of DC Cumulative Compound Motor:Elevator, ConveyorHeavy PlanerRolling MachineAir CompressorShearing and Punching MachineIntermittent High Torque Load, etc...Type 4: DC Differential Compound Motor:Applications Of DC Differential Compound Motor:Light LoadFor Constant Speed Drive, e.g. Paper Mill Drive, etc...
Why do you control the speed of DC motors?
because dc motor is a powerful & dangerous motor it is akiller

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 is alternating currentrather than direct current normally used in most installations?
electricity is essentially alternate in nature when generated (other than batteries). AC is more flexible for stepping up or stepping down. DC motors are little complicated compared to AC motors, hence AC gained popularity, though in the very begining DC motors were popular. In some specific applications, DC is still used in industry. Most of the Toy motors are DC
Are the fan motors on fanuc ac spindle motors ac or dc?
usually ac 110v even on the dc motors
What are applications of space vector modulation?
Because there's sparking in DC motors, they are inherently less efficient than say AC motors are, The trick with AC motors is that they run primarily at the frequency of their power source. What happens when the power source can change it's frequency and amplitude? The motor can behave as well as any DC motor.
