Is stepper motor ac or dc motor?
neither. DC locks the rotor of a stepper stationary, pulses applied to a stepper's windings in one order advances it while in the opposite order reverses it. steppers typically have 4 to 6 windings.
Is the dc shunt motor does not have any brushes?
No. A d.c. 'shunt' motor is one whose stator's field windings are connected in parallel with its rotor windings ('shunt' is simply an archic term for 'parallel'); it does not mean that the rotor can function without brushes.
If you crank the shaft of a dc motor manually will the motor become a dc generator?
It depends on both the wiring of the motor and what if any residual magnetic field remains in the field windings. If there is some residual field, you will get some volts, but not many. If the motor has permanent magnets, it is effectively a dynamo.
How do you counter the induced voltage spark during the generator?
By creating a rotating electric field. The generator has two main sets of windings - the field windings (the spinning ones on the rotor usually) and the stator windings(the stationary part connected to the grid). The field windings are electrified to create an electromagnet out of the rotor. Spinning the rotor creates a rotating electric field, which induces a voltage on the stator windings.
What is DC motor?
A DC motor is an electric motor that runs on direct current (DC) electricity. A DC motor is designed to run on DC electric power. Two examples of pure DC designs are Michael Faraday's homopolar motor (which is uncommon), and the ball bearing motor, which is (so far) a novelty. By far the most common DC motor types are the brushed and brushless types, which use internal and external commutation respectively to reverse the current in the windings in synchronism with rotation.
What type of dc motor has its field winding in parallel with its armature windings?
Shunt Motor
How is a DC permanent-magnet motor reversed?
Reverse the polarity of armature windings of the motor.
What is interpole winding in DC machine?
For a D.C motor it is the field windings which must always be in series with the armature windings.
Is stepper motor ac or dc motor?
neither. DC locks the rotor of a stepper stationary, pulses applied to a stepper's windings in one order advances it while in the opposite order reverses it. steppers typically have 4 to 6 windings.
Is stepper motor is AC or DC?
neither. DC locks the rotor of a stepper stationary, pulses applied to a stepper's windings in one order advances it while in the opposite order reverses it. steppers typically have 4 to 6 windings.
Is the dc shunt motor does not have any brushes?
No. A d.c. 'shunt' motor is one whose stator's field windings are connected in parallel with its rotor windings ('shunt' is simply an archic term for 'parallel'); it does not mean that the rotor can function without brushes.
How Synchronous motor work with principal?
A synchronous motor comprises of a stator windings and a rotor with a squirrel cage and inside that is windings(coils). At starting, this motor is an induction motor running with slip. After the rotor has reached a certain speed, a DC current is applied to the windings inside the squirrel cage. A fixed field is induced in these windings. This field locks in with the synchronous rotating magnetic flux of the stator windings. The rotating stator windings then pull the rotor along. The amount of excitation current can be used to control the power factor of the motor, making this a popular type of motor for high power use with a constant mechanical load.
What is commutation in DC machines?
It is the process of conversion of generated ac voltage into the armature of a dc generator to dc voltage at the terminal of the dc generator by use of pair of brushes and commutator. OR It is the process of conversion of given dc voltage at the terminal of the dc motor to ac voltage in the armature windings in a dc motor by use of pair of brushes and commutator.
The windings of an AC motor are called?
Windings

What is DC shunt motor?
A shunt DC motor connects the armature and field windings in parallel or shunt with a common D.C. power source. This type of motor has good speed regulation even as the load varies, but does not have the starting torque of a series DC motor
