What is excitation of a DC motor?
DC Voltage
How do you differentiat dc motior and ac motor physicaly?
if you power an ac motor with dc or a dc motor with ac you will likely start smelling smoke and the motor will be damaged. If the motor is marked "3-phase", "shaded pole", or "induction" it is an ac motor! BTW, there are ac/dc motors that will run on both, they are wound very much like dc motors but a bit differently.
Can you convert a DC motor to run on AC?
The easiest way would be to convert the AC power to DC by using a rectifier diode and a filter capacitor. In that way you can now run your DC motor on DC.
Why a DC motor is called DC motor?
DC, in DC motor, is an acronym for Direct Current, which means that it works on direct electrical supply by a battery. In an AC motor, the motor runs on Alternating Current Supply from other sources other than batteries, such as electricity from your house.No, d.c. is not an acronym. It is simply an abbreviation."a word formed from the initial letters or syllables taken from a group of words"http://www.thefreedictionary.com/acronymYes, a word. "dc" is not a word.
What would cause a meter to read negative voltage across a DC motor?
A DC motor generates power when it is rotating even when no supply is connected.
In what two ways can the rotation of a shunt connected dc motor be reversed?
DC shunt motor can be reversed by changing the polarity of either the armature coil or the field coil.
How do you Reverse direction on a DC motor?
a general purpose D-C motor can be reversed by changing the polarity of either the armature or the field but not both
How can the direction of rotation of a DC shunt motor be reversed?
DC shunt motor can be reversed by changing the polarity of either the armature coil or the field coil.
Why rotor of a dc motor moves in the anticlockwise direction?
Positive and negative are reversed. It will run either direction depending on which way it is wired.
How you can solve the problem for one of a dc motor that connected to pulse width modulation and this motor didn't start?
check the brushes if you are getting dc out of the drive and the motor doesnt start the motor should also have full field to start with an extreme overload even a permanent magnet can be discharged or reversed this is assuming the pwm drive is ok
What would cause an electric motor to run backwards?
Motors running backwards: A DC motor wired backwards or magnetic field reversed. A 3 phase AC motor with 2 phases reversed A single phase motor will run either way unless it is 'persuaded' by means of a shaded pole or other method to rotate in a particular direction.
What happens if the direction of current at the terminals of a series motor is reversed?
No changes will occur by wiring a 110 volt motor in reverse polarity, rotation will always be the same. Some single phase motors are designed to be reversed ,but that is a function of the relationship of start windings and capacitors and requires some wiring changes in a motor junction box or an end terminal housing, not by just changing the incoming power.
How can a capacitor start motor be reversed?
by reversing the connection of the two windings
What is a DC shunt motor?
A DC shunt motor is a motor using DC supply with the the inductor connected parallel to the armature.
What are uses of bidirectional dc motor?
6V dc motor
What is dc motor with synchoronous operation?
A synchronous motor is an ac motor that does not run on dc.
What is the dc motor?
Almost all the electro-mechanical movements we see around us are caused either by an A.C. or a DC motor. Here we will be exploring this kind of motors. This is a device that converts DC electrical energy to a mechanical energy.Principle of DC MotorThis DC or direct current motor works on the principal, when a current carrying conductor is placed in a mgnetic field, it experiences a torque and has a tendency to move. This is known as motoring action. If the direction of current in the wire is reversed, the direction of rotation also reverses. When mgnetic field and electric field interact they produce a mechanical force, and based on that the working principle of dc motor established.
