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.
Is the electric motor in a Ford Fusion hybrid AC or Dc?
It is an AC powered vehicle. It has an 88KW Magnet AC Synchronous Motor
When the induction motor working as induction generator?
An induction motor connected to an existing ac supply normally runs at less than the synchronous speed by an amount described as the 'slip' which is proportional to the torque demanded at the shaft. If the same motor is instead coupled to an engine and driven at a speed higher than the synchronous speed, with negative slip, power then travels back into the ac supply and the motor has become a generator. The amount of power produced depends on the speed. However a normal induction motor will not behave as a stand-alone ac generator. For ac power generation synchronous generators are invariably used because it is necessary to set and maintain the frequency of the supply accurately.
What is the difference between synchronous motor vs induction motor and which one is better?
The big difference is that the synchronous motor's rotor can have a variable current applied to it through its field slip rings. Both types of motors have their own advantages. With a synchronous motor in the system, the systems power factor can be regulated.
Why synchronous motor called double excited motor?
AC and DC supply sources we are given to motor so we are called double excited motor
Why synchronous motor is used in ac and dc?
A synchronous motor is used only with a.c. Its speed is dependent on the frequency of the a.c.
What is dc motor with synchoronous operation?
A synchronous motor is an ac motor that does not run on dc.

What is the similarity between an AC induction motor and an AC synchronous motor?
Only Stator winding is similar in both the cases.

What factors determine the synchronous speed of an AC motor?
Number of poles and supply freqency determines speed of synchronous motor. For speed control of such motors Variable Freqency Drives(VFD) are used.
Why synchronous motor called double excited motor?
AC and DC supply sources we are given to motor so we are called double excited motor
What is a synchronous generator?
Synchronous generators are the majority source of commercial electrical energy. They are commonly used to convert the mechanical power output of steam turbines, gas turbines, reciprocating engines and hydro turbines into electrical power for the grid. (OR) A "synchronous" generator runs at a constant speed and draws its excitation from a power source external or independent of the load or transmission network it is supplying. A synchronous generator has an exciter that enables the synchronous generator to produce its own " reactive" power and to also regulate its voltage. Synchronous generators can operate in parallel with the utility or in "stand-alone" or "island" mode. Synchronous generators require a speed reduction gear
What are the different types of AC motor?
slip ring, synchronous, and squirrel cage induction motors....
How do you control the speed on an ac motor?
the speed of ac motor can be controlled by controlling the synchronous speed (Ns=120f/p). and synchronous speed can be varried or controlled by changing frequency or by changing poles. but practicaly pole can not be changed. but we can change the frequency. the frequency can be VFD (Variable frequency Drives). so the speed of ac motor can be chaged or controlled by VFD.
