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.

How does the starting of synchronous motor using dc generator as a load work-?
Starting of the synchronous motor using the DC generator creates a magnetic field.
Type of dc motor used by fan?
Synchronous motor or induction motor
Why do you give DC excitation to AC Synchronous motor?
If the synchronous motor is running near synchronous speed, it will begin rotating at synchronous speed when DC is applied to the rotor. Source: Electrical Machines, Drives, and Power Systems Theodore Wildi Section 17.3
What is Commutatorless DC Motor?
A commutator less DC motor is nothing but a self controlled synchronous motor is being widely used in industries for high speed and large capacity.
Does a induction motor need excitation?
The induction motor is the special kind of motor which runs below and above the synchronous speed. which the synchronous motor runs nearly equal the synchronous speed. The operation of synchronous motor runs with dc field excited hence separate dc field current is given to the field circuit. where as the induction motor the field and main field is drawn from the same supply hence no excitation is required. But due to this separate starting mechanism has to be required in case of the single phase induction motor.
What is dc motor with synchoronous operation?
A synchronous motor is an ac motor that does not run on dc.
How does the starting of synchronous motor using dc generator as a load work-?
Starting of the synchronous motor using the DC generator creates a magnetic field.
Is reluctance motor is a synchronous motor with dc excitation?
yes
Type of dc motor used by fan?
Synchronous motor or induction 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.
Why do you give DC excitation to AC Synchronous motor?
If the synchronous motor is running near synchronous speed, it will begin rotating at synchronous speed when DC is applied to the rotor. Source: Electrical Machines, Drives, and Power Systems Theodore Wildi Section 17.3
What is self control of synchronous motor drive?
the self control of a synchronous motor is done using an inverter fed through a dc link.speed is controlled by varying the output frequency of the inverter by controlling the dc link voltage

Why synchronous motor called double excited motor?
AC and DC supply sources we are given to motor so we are called double excited motor
Working principle of synchronus motor?
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.
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
