Magnets manufactured for industrial usage are called industrial magnets. There are different types of industrial magnets which are meant for serving different purposes. These include individual magnets, bulk magnet materials, magnetic assemblies, magnetic sweepers, magnetic lifts, magnetic sheet handlers, magnetic retrievers, and permanent electromagnet combinations.
Two major aspects which should be considered while selecting these magnets are strength and holding force. The maximum energy product is also known as the magnet strength or grade. The force which the magnet is capable of holding under ideal conditions is called as the holding force. There are certain things like the size and shape of the parts, the surface conditions, motion, vibration, friction, holding angles, and machining forces which affects the holding force of the magnet.
Shapes and Sizes
These magnets come in the following shapes of different sizes:
- Block or bar flexible strip or sheet
- Sheet or slab
- Horse shoe or U-shaped
- Button or pot
- Round ring or disc and sphere bead arc segment
- Rotor or poles
The important specifications of industrial magnets include length, height, diameter, width etc. These can be non magnetized, conventional magnetized and multiple magnetized. After been assembled in the magnetic circuit a non-magnetized magnet can be magnetized. The conventional magnets can be magnetized through the thickness, length, or diameter. The conventional magnets have two poles at their end. Whereas, the multiple magnets have multiple poles.
There are different types of industrial magnets with different magnetic strength, flexibility, brittleness, tensile strength, density etc. The types of magnets which are used for various purposes are ceramic, alnico, neodymium, samarium cobalt, bonded neodymium etc.
These magnets have wide applications both industrial and non industrial. Some of the important applications of the industrial magnets are:
- Rotary motors
- In servo motors
- Pump couplings
- Satellite system
- Linear actuators
- Computer disc drive
- Electric motors
- Automotive and electronic sensors
