Magnets do the following things:Attract certain materials – such as iron, nickel, cobalt, certain steels and other alloys;Exert an attractive or repulsive force on other magnets (opposite poles attract, like poles repel);Have an effect on electrical conductors when the magnet and conductor...
About 4,000 years ago, dug up the earth to find Magnes lodestones. Lodestones contain magnetite, a natural magnetic of Fe3O4. This type of rock was subsequently named magnetite.
From the historical point of view the development of permanent magnet materials, the late nineteenth century the use of...
1. The magnetized permanent magnets with strong magnetic field attract the iron and other magnetic matters around them greatly. Under common condition, the manual operator should be very careful to avoid any damage. Due to the strong magnetic force, the big magnet close to them takes the risk of...
Sintered NdFeB magnet used to be the widest applied material due to its high properties and cheap price rather than SmCo magnet. However in 2011 the situation changed a lot. MAGNETC Engineering professionally advises SmCo as a replacement of NdFeB in special application.
We advise SmCo to replace...
Always take care! Magnets can snap together and injure personnel or damage themselves.Keep magnets away from magnetic media – such as floppy discs magnet and credit cards – and computer monitors.Store magnets in closed containers, so that they do attract metal debris.If several...
A magnetic motor (or magnet motor) is a device which converts power of or relating to or caused by magnetism (e.g., "magnetic forces") into mechanical force and motion, with no other input. It usually provides rotary mechanical motion. The machines that utilizes the properties of a magnet for...
The Magnet motor (or magnet engine) free energy generator is a decent, powerfull and well-looking topology of a free energy generator. It works on a principle of the powerfull neodymium permanent magnets. When the magnetic force reachs the necessary level to overcome the friction, the motor RPM...
Many over-unity researchers are attempting to harness the unique properties of pulsed motors. The Orion Project has started to conduct research on devices that will ultimately be able to self-power and provide enough additional electrical energy to cover all the requirements for an average home. A...
A brushed DC motor is an internally commutated electric motor designed to be run from a direct current power source. Brushed motors were the first commercially important application of electric power to driving mechanical loads, and DC distribution systems were used for more than 100 years to...
AC motors are also fairly simple to understand. They are a little trickier to make but will need single-phase or three-phase AC power to make them work. In the little diagrams above, we have a squirrel cage ac induction motor, a permanent magnet synchronous machine, and a...
In any electric motor, rotation is caused by two magnetic fields that oppose each other. In some motors, both fields are created by coils of wire - electromagnets. In other motors, one field is electromagnetic and the other comes from one or more permanent magnets.In the permanent magnet (PM)...
It’s obvious that the motor you use is the most important part of your wind power generator. If you’re new to building a small wind turbines, then you’ll find that this can be one of the most confusing (and controversial) aspects to the process. Motors, generators, alternators,...

The Orion Project has started to conduct research on devices that will ultimately be able to self-power and provide enough additional electrical energy to cover all the requirements for an average home.

Identical hand-cranked generators can be used to show that a generator can function as a motor and vice versa. If mechanical energy is put into the one of the devices by turning the crank, electrical energy can be produced. If that electrical energy in the form of voltage is applied to the other,...
The Brushed DC Motor gets its name from the "brushes" used for commutation. Here are some key points about the brushed DC motor:
Typically the rotor, also known as an armature, has windings on it terminated on to a commutatorBrushes make and break contact with commutation segments, thus...
When a current passes through the coil wound around a soft iron core, the side of the positive pole is acted upon by an upwards force, while the other side is acted upon by a downward force. According to Fleming's left hand rule, the forces cause a turning effect on the coil, making it rotate. To...
As of today, there still are no plans that I know of that surely result in a magnet motor. However, that could change in the next few weeks, as someone has come forward with a design that they are talking about open sourcing. I'm in process of getting those, having a few built to confirm the...
Servo motors have been around for years. Because of their small size, they are widely used by hobbyists and collectors to operate remote-controlled or radio-controlled toy cars and robots and even airplanes. Servo motors can also be found in one form or another in industrial devices where robotics...
A stepping motor is a small electric motor that converts digital pulses into mechanical rotations. Every revolution of the motor is a small, discrete step controlled by a digital pulse. Each step is the same size and requires a separate pulse. As the pulses increase in frequency, the stepping motor...
The piston rings fit into horizontal grooves in the pistons. The rings expand against the cylinder wall and seal the combustion chamber. This ensures that the engine maintains a consistent level of compression. Stuck piston rings are uncommon, but they do occur. There are two positions in which the...
Building your own wind turbine generator is no small task. Wiring the DC motor to the rest of your renewable energy system requires advanced knowledge and experience with electrical systems and involves connecting several different components to your turbine. Depending on your skill level,...
Wind turbines are a viable--and at times less costly--alternative to installing solar panels in residential settings. All wind turbines use a permanent magnet motor to generate direct current electricity. Although home appliances cannot utilize direct current, obtaining an AC power inverter will...
There are many different types and sizes of electric motors. Electric motors can be divided into two types: Alternating Current (AC) motors and Direct Current (DC) motors. An AC electric motor requires an alternating current, while a DC motor requires direct current.
AC motors are further...
DC or direct current motors are the most efficient electrical motors on the market today. Understanding the basic layout of a DC motor can go a long way in the troubleshooting and repair of the motor. There are two major components of an electrical motor called the stator and the rotor. Generally a...
One of the most common varieties of electric motors is the brushed direct current (DC) motor, which can be found in numerous electrical applications. Like all electric motors, they rely on a constantly changing magnetic field between stationary and rotating magnets. Brushed DC motors consist of a...
A DC motor works by using the power of magnets. Opposite poles on magnets attract each other, whereas similar, or like, poles repel. A permanent magnet DC motor uses a field magnet to set up a static magnetic field. An armature with an arrangement of electromagnets is connected to an axle. The...

Magnets produce magnetic fields, or areas in which potentially magnetic materials, such as iron, are polarized and attracted to the magnet. There are two types of magnets: permanent magnets and electromagnets. Permanent magnets have a constant magnetic field, while electromagnets only produce a...
