How many types of DC motor?
Types of AC MotorsClassification Based On Principle Of Operation:(a) Synchronous Motors.1. Plain2. Super(b) Asynchronous Motors.1. Induction Motors:(a) Squirrel Cage(b) Slip-Ring (external resistance).2. Commutator Motors:(a) Series(b) Compensated(c) Shunt(d) Repulsion(e) Repulsion-start induction(f) Repulsion induction
What is the speed of DC series motor at no load?
No load speed is the speed that the motor run when it has no load, i.e., the motor is separated from the engine, that speed is than greater than the rated speed, because the rated speed is the speed whwn the motor are linked to the load and it is the full load.
Why is a synchronous speed motor considered a constant speed motor?
synchronous motor is a constant speed motor because it will only run at a synchronous speed or not at all.the speed can be changed by changiing the frequency only ns=120f/p
Which DC motor is constant speed motor?
Dc shunt motor is constant speed motor.Its speed is constant with armature current.This shunt motor is used in paper mills and drilling machines
Will an ac motor run backwards if polarity is reversed at the outlet?
No, unless it is a three phase motor and you reverse only two of the phases.
How can a capacitor start motor be reversed?
by reversing the connection of the two windings
How can a reversal motor be reversed?
69 69 69
How is a DC permanent-magnet motor reversed?
Reverse the polarity of armature windings of the motor.
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 direction of a split phase motor can be reversed?
reverse wires

What is overlap repulsion in physics?
overlap repulsion in physics is repulsion overlapped

No, unless it is a three phase motor and you reverse only two of the phases.
What is the unit of speed of rotation of a motor?
Motor speed is a term we often use to speak to the rotational speed of a motor. And often we talk about the speed of rotation in revolutions per minute, or RPM.
