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.

What causes the axle to spin in an electric motor?
Switching the field voltage to the coils forces the magnets to move.
How do you store the 30 volts produced from spinning an electric motor?
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.
Why the DC motor is call as synchronous motor?
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.
What does the brushes and commentator in a D C motor do?
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.
What joint allows connected shafts to spin freely while permitting a change in direction?
universal joint
What is a device that has a magnetized needle that can spin freely?
A compass has a magnetized needle that can spin freely.
What is a device that has a magnetized needle that spin freely?
A compass has a magnetized needle that can spin freely.
In an electric motor a magnetic field causes what to spin?
The rotor (which is some type of magnet).
What must happen for an electric motor to spin?
suitable winding and correct power supply
What causes the axle to spin in an electric motor?
Switching the field voltage to the coils forces the magnets to move.
What is a motor in physical science?
A motor is a mechanism that spins by means of electric energy and uses magnetism to spin. It uses energy.
Does water pump pulley move on 1999 chrysler cirrus?
It should spin freely, but not wobble.It should spin freely, but not wobble.
How Can you Make Something Spin In A Circuit?

What are fans powered by?
Most fans have an electric motor that runs off of electricity. These use magnetization to spin the fan

What are the parts of elecric fan?
You need, a electric motor, a power source (battery), blades or propeller to attactach tot he motor so when they spin the move (displace) the air.
When garbage disposer is turned on it hums and does not spin but if a stick is used to make it spin it then spins what is wrong?
I would say that either the bearings in the motor are worn out ,so the motor has a hard time turning. Or it may be that one of the motor windings (electric coils) is bad. I would replace the disposer.
