What else can I help you with?
As a motor armature turns faster and faster net current in the motor windings decreases or increases or remains unchanged?
as a motor armature speed increases,the net current in the motor windings decreases due to MAGNETIC DRAG. which is a common phenomenon in the ac machines.
Reverse direction of singlr phase ac induction motor?
The direction of a singular phase induction ac motor can be reversed by switching the capacitor in relation with the motor windings. When started in the reverse direction, the motor will maintain the same torque level that it had in the forward direction.
Where are the main windings of an AC induction motor situated?
Front and rear.AnswerThey are located in longitudinal slots that are machined into the inner surface of the stator.
Why dc motor is not named as conduction motor?
In dc motors, the electric power is conducted directly to the armature (i.e., rotating part) through brushes & commutator. Hence, in this sense a dc motor can be called as a Conduction motor. However, in ac motors, the rotor does not receive any electric power by conduction but by induction in exactly the same way as the secondary of a two winding transformer receives its power from the primary. That is why such motors are called as Induction motors. An induction motor can be treated as a rotating transformer i.e., one in which primary winding is stationary but secondary is free to rotate.
What motor can only operate on alternative current?
The name of the motor that can only operate on alternative current is called the AC motor. The AC motor consists of 2 basic parts with a rotor that is attached to the output shaft.

as a motor armature speed increases,the net current in the motor windings decreases due to MAGNETIC DRAG. which is a common phenomenon in the ac machines.
The part of an ac induction motor that turns is called?
The part of an AC induction motor that turns is called the rotor. The rotor is located inside the stator, which is the stationary part of the motor. When alternating current flows through the stator windings, it creates a rotating magnetic field that induces current in the rotor, causing it to spin and produce mechanical output.
HDD spindle motor is a stepper motor?
Sort of. More importantly, steppers and spindle drives are both examples of synchonous AC motors with a magnetised rotor and AC-excited stator windings.
Is a 3 phase motor a Synchronous motor?
A synchronous motor can be a type of 3-Phase AC motor, or not.A synchronous motor is defined by the period of the rotor being synchronized with the frequency of the stator windings' current. The stator windings might be 3-Phase or not (2-Phase would work).Also synchronous motors are not the only type of 3-Phase AC motors. An induction motor could also be 3-Phase AC and has a few advantages and disadvantages over a synchronous motor.
Reverse direction of singlr phase ac induction motor?
The direction of a singular phase induction ac motor can be reversed by switching the capacitor in relation with the motor windings. When started in the reverse direction, the motor will maintain the same torque level that it had in the forward direction.
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.
Where are the main windings of an AC induction motor situated?
Front and rear.AnswerThey are located in longitudinal slots that are machined into the inner surface of the stator.
Where are main windings of an ac induction motor situated?
Front and rear.AnswerThey are located in longitudinal slots that are machined into the inner surface of the stator.
What happend when you start motor without starter?
The windings of the motor will be gonebecause of high current diectly goes to the windings of motor.
How can I test an AC fan motor to ensure it is functioning properly?
To test an AC fan motor, you can use a multimeter to check for continuity and resistance in the motor windings. You can also visually inspect the motor for any signs of damage or wear. Additionally, you can test the motor by applying power to it and observing if it spins smoothly and quietly.
Why dc motor is not named as conduction motor?

What is the main part of ac motor?
shaft, windings, ball bearings, armature, stator, commutator, brushes, terminals, case.
