the starter
The motor has a coil of wire that is an electromagnet. This causes the motor to spin, turning the fan blades.
The rotor (which is some type of magnet).
When an electromagnet is connected to wires and a motor, the electromagnet generates a magnetic field when current flows through the wires. This magnetic field interacts with other magnetic fields in the motor, causing the motor to either spin or generate motion depending on the design and configuration.
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.
Switching the field voltage to the coils forces the magnets to move.
The inter changing of either the start winding or the run winding.
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 motor is 2
they spin when the motor reach a temperature, ussualy is on a 1/4 of temperature
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.
you should raise the rpm of the motor (not too much though) and when at the light, put the car in neutral. this reduces the drivetrain resistance, allowing the motor to spin more freely
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.
