Principle of synchronous motor is as given below:
"when a 3 phase winding is fed by a 3 phase supply, then a magnetic flux of constant magnitude but rotating at synchronous speed, is produced."
Principal : whenever a current carrying conductor is placed inside magnetic field, a torque exist on it which tends it to rotate.
Working : After interlocking of rotor and stator magnetic field motor start rotating on synchronous speed which is actually the speed of rotating magnetic field of stator.
Synchronous motors include electromagnets which creates a rotating magnetic field. The basic principles of these motors being that they rotate in sync with the frequency of the electrical supply.
Explain the Principle and working of synchronous motor
One big advantage of a synchronous motor is that it can be used for power factor correction when it is on line.
induction motor never runs at synchronous speed, if it does so there would not be any relative speed between stator flux and rotor and no emf will induce in rotor and we can not apply motor principle as we need current carrying conductor in magnetic field.
An induction motor rotating at higher than synchronous speed would be generating power, thus would be a generator. No motor operating as a motor runs above synchronous speed.
As per the operating principle of the Synchronous motor, due to continuous & rapid rotation of stator poles,the rotor is subjected to a torque which is rapidly reversing i.e. in quick succession,the rotor is subjected to torque which tends to move it first in one direction & then in the opposite direction.Owing to its large inertia,the rotor cannot instataneously respond to such quickly-reversing torque,with the result that it remains stationary or in other words it is not self starting.
A 60Hz synchronous motor spins at synchronous speed - if it's a two pole motor it will spin at exactly 1800 rpms. An asynchronous motor will spin at a speed lower than the power supply frequency - a symilar asynchronous motor may spin at 1700 rpms.
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.
It is a special type of synchronous motor.It works on the principle of hysteresis and the torque is produced due to hysteresis
A synchronous motor is a three phase motor, which uses a magnetic field created by permanent magnets or a DC electromagnet on the rotor (usually). The stator windings have 3 phase voltages applied, and coupled with the DC field, create a rotating magnetic field that drives the motor at synchronous speed.
motor works on the principle of mutual induction.
synchronous generator is similar to the principle of laws of electro magnetic induction that is "whenever the magnetic flux linking in a conductor that time emf is induced at the ends of the conductor "
mainly alternator,synchronous motor comes under the synchronous machine.a synchronous motor is not a self starting motor.if a synchronous motor moves with more than synchronous speed then it acts as a synchronous generator.
a synchronous condenser is over excited synchronous motor under no load
A synchronous motor runs at synchronous speed, so there is no slip, or zero slip.
A working principle is a regulation or rule that is used so that work can be done. This is a general phrase that can be used in any circumstance from the working principle of a motor, to the working principle of a solar cells.
A synchronous motor runs at synchronous speed, so there is no slip, or zero slip.
when generator works as a motor then the cuurrent path is reversd.
