Arc

Arc magnets can be made from powerful neodymium. They are often used in electric motors, alternators and generators or to create renewable energy from wind, solar and hydro power sources. Stators and Rotors inside electric motors use permanent magnets in the shape of an arc.

Arc

The arc magnet segments enable rotational movement by arranging the magnets with alternating negative and positive poles on the inside and outside diameters. This creates the attractive and repelling magnetic force inside the cylindrical motor body that is required to generate rotational movement at the driveshaft. The magnetic force and rotational speed is controlled by increasing or decreasing the electromagnetic field strength inside the windings. Magnetic fields that are generated by Permanent magnets to drive DC electric motors help conserve battery life. This makes cordless power tools convenient and provides a viable option to mains powered electric tools and appliances.

Other Arc Magnets are made from the significantly lower strength Alnico alloy which is widely used to produce typical Horseshoe-style magnets. Horseshoe shaped magnets are essentially a curved Bar magnet that has the North and South poles in much closer proximity. This increases the strength of the magnetic field and gives the magnet more holding power. It also reduces the level of demagnetisation that is a common problem with Alnico magnetic products and a metal keeper plate is also required for this purpose.
