Switching the field voltage to the coils forces the magnets to move.
In order for an electric motor to spin freely you will have to make sure you have one thing. You have to have the electric current for the motor to run freely.
A motor can be connected up to a car battery to store the power produced when it runs as a generator, but you will find that when current is drawn the motor needs more work to spin it, it will not spin so easily. That is because of conservation of energy.
You probably have one in your computer - any spinning disk uses a motor to spin (hard drives, DVD/CD drives, Floppy drives, etc.). If you have a phone that has that can vibrate, it has a small motor (the motor's rotor, or the center part that spins, has a small weight on it that is off-center - this is what causes the vibrations). Most fans are electric motors (air conditioning/heating fan in your car, etc.).
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.
i have never heard of a commentator in a motor, think you may be mistaking that word. inside an electric motor you have a stator and windings, as polarity changes it spins the stator and the brushes transfer the charge to the device being used.. I think they meant commutator. If you break an electric motor down to 2 parts, you have a commutator and an armature. the armature being the shaft that basically floats on bearings, and the commutator being the hull where the stator is. (and there is such thing as a brushless electric motor.) the stator does not spin. that is the term used for the magnets that pull the electric field supplied by the brushes. To make even more simple, imagine a shaft floating on bearings with 2 magnets on it, one positive and one negative ( the armature) and this shaft is inside of a ring of electricity the is flowing in one direction, its going to pull the negative and push the positive (the commutator) and cause the armature to spin.
In an electric motor, periodically changing the direction of current in the electromagnet causes the magnetic field to alternate. This changing magnetic field interacts with the permanent magnets on the rotor, creating a rotational force that causes the axle to spin. This process is known as electromagnetic induction.
The rotor (which is some type of magnet).
True. In an electric motor, a magnetic field causes a current-carrying loop to experience a torque that makes it spin. This spinning motion is the basis of how electric motors convert electrical energy into mechanical energy.

Electric motors convert electrical energy into mechanical energy to produce rotational motion. It operates based on the principles of electromagnetism, where the interaction between electrical current and magnetic fields generates a force that causes the motor to spin.

The motor has a coil of wire that is an electromagnet. This causes the motor to spin, turning the fan blades.
suitable winding and correct power supply
A motor is a mechanism that spins by means of electric energy and uses magnetism to spin. It uses energy.
An example of electrical energy changing to kinetic energy is the operation of an electric motor. When electricity flows through the motor, it generates a magnetic field that causes the motor to spin, converting the electrical energy into mechanical kinetic energy.
A simple motor works by passing an electric current through a coil of wire, creating a magnetic field. This magnetic field interacts with a permanent magnet to generate a force that causes the coil to spin. This spinning motion is what drives the motor to perform its function.
