Magnets for Electric Motors
Powering industries with magnets
Electric motors are vitally important in almost every primary industry. Focusing on one typical household, it’s common to find electric motors in every room, from large items like fridges and washing machines to hair dryers, laptops, electric razors, and power tools in the garden shed. Mechanical movement depends on electric motors and, in turn, magnets for electric motors.
Importance of magnets in electric motors
Magnets are an essential component in electric motors as they are used to generate rotational motion. As a basic unit, an electric motor will need a rotor, axle, power supply, brushes, field magnet, and commutator. The most important components are the magnets — the rotor (an electromagnet) and the field magnet (or permanent magnet). It’s possible to use two electromagnets, but to save power, it’s best to use a permanent magnet. Whether in industrial machinery or household appliances, permanent magnets assist high performance, sustainability and efficiency in motorised systems.
Applications of electric motor magnets
Electric motor magnets are used in diverse applications, too many to list here. Just a few examples include:
Industrial motors. In industry, electric motor magnets are used in motors such as stepper and servo motors in applications like conveyor systems or precision machinery.
Electronics. Vibrational electric motors in smartphones electric fans — these applications need reliable, lightweight, compact magnets.
Medical devices. Magnets for electric motors are a vital component in medical devices. These magnets provide benefits such as stability and accuracy within these applications, such as when used in centrifuges or MRI machines.
Electric vehicles (EVs). Neodymium magnets are used in EVs due to their superior strength for high-performance and compact electric motors.
Hybrid and electric aircraft. In their propulsion systems. This contributes to the future development of energy-efficient, environmentally friendly transport solutions.
Our Electric Motor Magnets
Alnico magnets are permanent magnets widely used as they have high corrosion resistance and can be used in high-temperature applications. Alnico magnets can be suitable if the application requires a very high-temperature operation, change in output with temperature variation or high field output.
Ferrite magnets are also known as ceramic magnets. They have superb machining properties, meaning they can be cut into different sizes and shapes relatively cheaply. They also have brilliant resistance to corrosion and demagnetisation.
Samarium Cobalt Magnets
Samarium cobalt magnets are permanent magnets with very stable properties. They are often used in high-tech fields such as aviation and military as they have superior temperature coefficients and corrosion resistance.
Neodymium magnets (neodymium iron boron magnets, ‘neo’ or NdFeB) are widely used in electronic technology and modern industry. These magnets are the most vital magnets commercially available and are manufactured in various shapes, sizes and grades.
We also stock pot magnets, which are used with a wide range of magnet materials, including alnico, ferrite, neodymium and samarium cobalt.
