The frequency of emf generated per rotation of the rotor depends on the number of poles on the rotor and on the field. Please restate your question.
For the two pole / two pole case, an atypical configuration, but good for illustration, 3,600 RPM would generate 60 Hz.

When induction motor is switched on the rotor frequency is?
The induction motor rotor has different frequency compared to it's stator. The rotor has slip ( s ) frequency. slip = ( Synchronous speed - rotor speed ) / Synchronous speed Synchronous speed = ( 120 * f ) / P where f = supply frequency to the stator. p = no of poles rotor speed is the actual speed the motor is running. Frequency in the rotor = slip * frequency in the stator At starting rotor speed is zero, so slip is one. Let us take the supply frequency is 50 Hz, then rotor frequency is also 50 Hz at starting. The motor attains speed and runs with its full speed at a point of time. Then let us take the slip is 0.04 then the rotor frequency will be 2 Hz.
What is difference between frequency and slip frequency?
Both 3-phase induction motors and single-phase induction motors have rotating magnetic fields assuming that the single-phase motor has one of the usual starting mechanisms built-in. The synchronous speed is given by RPM = 120 X f / p where f is the frequency and p is the number of poles. The conductors in the rotor pass through the magnetic field of the stator at the slip speed. As a result an alternating current is generated in the rotor. The frequency of that current is the rotor frequency or slip frequency given by slip frequency = slip speed X p / 120. At full load, the slip speed of a standard, 3-phase motor is about 1% to 2.5% of synchronous speed. A motor with 6% slip would be classified as a high-slip motor. The slip of a standard single-phase motor could be 6%.
Why speed regulation does not apply in dc series motor?
A series motor can run away and reach a high speed on no-load, which happens because it accelerates until the back emf generated in the rotor is nearly equal to the supply voltage. On no-load the current and therefore the field are both small, so the motor speed has to rise to equalise the generated voltage.
Does the value of the exciting current of your 3-phase motor depend on the rotor speed?
An induction motor has no excitation, so the question is about a synchronous motor. The rotor speed is determined by the supply frequency. For a given supply frequency and mechanical load, the excitation current can be adjusted to give the best power factor.
How a rotaing magnetic field is generated in an induction motor?
The magnet is the stator part of the motor, either as a permanent or an electromagnet. It draws the rotor past of the motor towards it causing the rotation. As it does this the brushes of the motor now lose contact with that section of the rotors many coils and switch to next segment on the commutator (copper segments the brushes run on). This new coil becomes magnetised and is again drawn to the stator magnet and so on.

What is the governor of a synchronous generator?
The governor of the synchronous generator is the device that controls the torque of the rotor, and thus the frequency of the generated alternating current. This is important if the power plant is directly coupled to a transmission system.

What does a stator do on motorcycles?
If we are talking about a dynamo or an alternator, a stator has a rotor inside it. When the rotor turns, electricity is generated.
Why rotor rotate?

How does a high frequency induction motor work?
In a high frequency induction motor, EMF is induced leading to current flow. Torque in the rotor coil increases. As frequency increases, Impedance of the Rotor increases and currency reduces.

How is single phase induction motor is constructed?
An induction motor is an alternating current (only) motor that has one or more coils of wire wound on a metal frame that induces a current in the conductors in the rotor when the rotor is moving at a different than synchronous speed. Synchronous speed it determined by the line frequency and the number of poles the motor has. For example, a two pole motor with a 60 Hz line frequency would have a synchronous speed of 3600 RPM. When used with single phase, the magnetic field generated in the stator needs to be caused to rotate around the rotor. In most cases this is initiated by a separate starting winding that is fed out of phase with the running winding(s). Once the rotor is rotating, the stator's field rotation has been established and the starting circuit is generally switched off.
