Which Shape Of Magnet Is Used In a DC Mini Motor?
Rare earth permanent magnet materials are being utilised in electrical applications more and more due to their improved performance. Using high-performance rare earth permanent magnet materials to create a motor eliminates the need for a specialised electrical excitation system, improving motor efficiency and power factor while saving energy and reducing motor size.
Lihua Motor has 2 main shapes of motor magent:
Strip magnets,name for cirle-shaped magnets,has a great flexibility.One of typical magnets types,strip magnets are commonly used in RF-500 motor,RF-370 motor .And strip magnets are shaped into a circle shape ,then assemble into motor housing.They didn't need circlip that connected and fixed with magnets.
Tile magnets, another name for arc-shaped magnets, are frequently found in various electric motors and generators. They are also utilised in torque couplings because of their north and south polarities. The most popular motor magnet shape is still arc, particularly for DC motors and magnetic rotors.Tile magnets must need circlip or other structures to fix them.
- Magnet Power: Tile magnets have more magnet power than strip magnets.For 12V/24V/36V motor ,motors will use tile magnets to assemble.
- Structure: For a motor,if we use strip magnet, it may only need one strip to assemble withiout circlip.But if we use title magnets,one motor need two pieces to assemble.Comparing to the structure, the strip magnet is more stable than title magnets.
- Unit price: The process of title magnets are more difficult than strip magnet.So the price is higher than strip magnet.
- If you want to choose the suitable magnets for mini motor, you can consider from following factors.
- If higher output power and performance stability are required, larger and stronger magnetic tiles can be selected
- If cost is considered, magnetic strips are low cost, resistant to high temperatures and not easy to demagnetize, but the magnetic field strength is relatively weak.
- If you consider that the product needs to operate in a high-temperature environment, choose magnetic tiles with good temperature characteristics.
With the development of the market, magnetic materials are widely used in industrial equipment. So far, motors are the most used in the industrial field. Permanent magnets are an important core component of permanent magnet motors. When you choosing the mini micro motor,you also need to know how to select the suitable magent for your product.Price,raw material, resistance are key points you must concerned.
