How-To: Motors. Before we can really begin addressing how a motor works, lets focus on what a motor does. A motor uses electromagnetism to create motion, converting electrical energy into mechanical energy. Magnetic fields produce physical force that can move things. Every magnet has a magnetic field with a north pole and a south pole. If you try to push the north poles of two magnets together, they will repel each other. The same thing happens if you try to push two south poles together.
An electric motor uses the attraction and repelling properties of magnets to create motion. In an electric motor, the electromagnet is placed on an axle so it can spin freely inside the magnetic field of a permanent magnet. Motors are classified by having the following properties: There's a permanent magnet (or magnets) around the edge of the motor case that remains static, so it's called the stator of a motor.

Electric Motor Quiz" EBE Technical principles. The DC solenoids featured here are predominantly pull-type lifting solenoids. They feature an open design (protection class IP00). Standard versions are illustrated in the type sheets. In many cases it is recommended that the lifting solenoid be adapted to suit the relevant application. The armature is generally reset via a return spring; non-standard versions may also be supplied with a built-in return spring. It is secured by a thread in the solenoid frame. Fastening screws that are too long must not be selected as they may damage the solenoid coil.
Solenoid force Solenoid force is the usable force output by the lifting solenoids in the lifting direction. Solenoid stroke The solenoid stroke is the path covered between the start and end position of the armature. Work The work exerted is the integral of force over stroke (area under the characteristic curve). Force-stroke curve The force-stroke curve illustrates the relation between solenoid force and stroke. Operating voltage Operating mode.
