A magnetic motor assembly is a kind of perpetual motion device, which is meant to generate a continuous rotation in any stator or rotor by the application of permanent magnetic magnets on it without any external power source. These motors are theoretically achievable and practically feasible. However, their working principle is usually misunderstood and complicated by most people. This misunderstanding leads to inappropriate working procedures and frequent breakdowns which may endanger the life of the operator.
A motor magnet is basically an electro-mechanical device that utilizes the action of constant mechanical energy to produce a change in the state of its surroundings. The mechanical energy comes from the repulsion and attraction of the permanent magnets. When such repulsive and attractive forces are placed on the stator threads, they cause the threads to move. When the stator threads are moved by the force exerted by the motor magnet, then mechanical energy is produced.
In order to build a motor magnet, you must understand the working principle behind these magnets. These magnets are actually made up of iron and other strong metals, but you need not worry if you do not have them. You can easily find motor magnets that are made of various other materials such as aluminum, brass, stainless steel, and many others. The materials are available in different shapes and sizes. You will just have to choose one that suits your needs.
In order to understand the working principle behind a motor magnet, you must first know about the magnets that create the torque. The most important thing to note first is that the strength of the magnet's attraction or repulsion is directly proportional to the magnetic torque. The magnetic torque is also referred to as the magnetic field strength. The torque is measured in units of magnetic force or torque. A higher value means that the force is stronger than the gravitational pull of the earth on the magnet.
Now that you know how the torque acts, let us look at how they are used in Electric Motors. Electric motors use the strength of the magnetic force to induce motion into it. This is done by passing an electric current through the stator or pole of the motor. The current induces a rotation in the outer casing of the rotor. The inner core acts as a permanent magnet and holds this rotation, thus producing a power output of the electric motor.
To apply this principle to electric motors, we need to understand the concept of permanent magnet motors. If you want to use a motor magnet for motion control, then you need to attach a magnet on both the input terminals of the motor. The permanent magnets will act like a lever and will push both the terminals in towards one another.
This will create a strong magnetic field that will force the rotor to move. If you are using a permanent magnet motor for the first time, it is important to remember that you need strong magnetic fields around the permanent magnet material. You can test the magnet's attraction-repulsion property by placing iron filings onto the magnet. A strong magnetic field will push the iron filings into the magnet. This is the same as a permanent magnet material pushing against a strong magnet's attraction.
When the rotor is placed inside a magnet, the attraction-repulsion law is applied. The current induced in the motor will cause the magnet to change states from a positive charge (ferrous) to a zero charge (non-ferrous). At this point, the magnetic dipoles will be forced to align with the strongest of the magnets, creating a force that acts upon the motor. To complete the circuit, you should remove the magnet and have it fall into the hole created by the demagnetizing force.
