Features Constant speed, achieving synchronous speed. High power factor: A well-designed motor can achieve a power factor close to the value of 1.0. Compact size, lightweight, and low noise. High efficiency: During normal operation, there is no copper loss in the rotor. The high power factor results in a smaller rotor current and reduced copper losses in the rotor windings. The motor's speed is directly proportional to the frequency, simplifying the control system. The motor can be designed with multiple stages and low-speed high-torque capabilities, eliminating the need for a gearbox and enabling gearless transmission. Wide speed range, with a high-speed design that can reach up to 10,000 revolutions per minute (rpm).

Neodymium magnets (also known as NdFeB, Neo or NIB magnets), are strong permanent magnets made from an alloy of neodymium, iron & boron. Part of the Rare-Earth magnet family, they have the highest magnetic properties of all permanent magnets. Due to their high magnetic strength and relatively low-cost, they are the preferred choice for many consumers, commercial, industrial and technical applications.NdFeB is divided into sintered NdFeB and bonded NdFeB. Bonded NdFeB is magnetic in all directions and corrosion resistance and is divided into Bonded Compression NdFeB Magnet and Bonded Injection NdFeB Magnet; while sintered NdFeB is easy to corrosion, the surface requires coating, generally divided into axial and radial magnetic charging. Advantages of Sintered NdFeB Magnet : 1. Very hard and brittle, high diamagnetic resistance, high cost / performance ratio, not suitable for high working temper ature; 2. Magnetic performance is higher than that of the rare earth cobalt permanent magnet, the residual magnetic induction strength, magnetic induction coercivity, the maximum magnetic energy product is very high, is the current magnetic performance of the best permanent magnet; 3. High cost performance.

AINiCo is composed primarily of Aluminum Nickel Cobalt and also Copper and Titanium. They are manufactured through either casting or sintering process. Cast AINiCo may be manufactured in complex shapes such as horseshoes not possible with other magnet materials. Sintered AINiCo offer slightly lower magnetic properties but better mechanical characteristics. it can be efficiently magnetized in any direction, and for anisotropic AINiComagnet, it generally has greater magnetic capacitive in a preferred orientation than isotropic types. AINiCo is hard and brittle, Machining or drilling cannot therefore be accomplished by ordinary methods. Holes are usually cored in at the foundry, and magnets are cast close to final size and then finish machined to closer tolerances. â?¢ Advantages of AlNiCo Magnet: 1.Customized designs are available. 2.Max working temperature can be as high as 550�°C. 3.Disadvantage: Br and BH(max)are not as high as rare earth magnet. 4.High energies and relatively low coercivity. 5.High magnetic flux density; low mold charge stable temperature properties; easy to shap.
Flexible magnets are low-cost extruded permanent magnets made by bonding a strontium magnetic powder ina flexible vinyl binder. Microcrystalline magnetic powder of flexible magnet leads to its high magneticperformance, and artificial rubber makes it very flexible.

Size:6.35x38.1mm Grade:n52 Axially magnetized This cylinder magnet can be applied for magnetic sensors. Magnetic cylinder sensors are mainly used to monitor the piston position on cylinders and grippers. The field of the magnet integrated into the piston is detected by the sensor through the actuator wall. Thanks to the contact-free position detection method, magnetic cylinder sensors are reliable and wear-free: no loss of contact material, no impacts, no adhesion, and only one switching point. Moreover, this cylinder neo magnet can also be applied for magnetic stir bar. If you are looking for magnetic rod at this size, we won¡¡¥t charge any molding / tooling fees cuz we have had all these necessary molds. Both axially magnetized and diametrically magnetized magnets are available. Before mass production or purchase order placed, we will mail samples to our customer for their confirmation. Samples usually are free while customers have to pay for the freight. Usually for small order, our lead time is about 2 weeks. Fast delivery can be ensured. We have not received any complaint about the quality of our magnets such as magnetic property losing after a period of time or coating peeling and so on..

Fast Delivery: when you choose the item and decide your design, we can produce it as fast as possible. 5. If you would like to make an enquiry, how can you contact us? 6. The way of identify the pole of magnet: The easiest way is to make a dot on the North or South or both Poles. If you need, we can make the dot as your requirement 7.Is one pole stronger than the other? No, both poles are equally strong 8.Which is the strongest type of magnet? Neodymium (more precisely Neodymium-Iron-Boron) magnets are the strongest permanent magnets in the world. 9.Can you supply BH Curves, or Demagnetization Curves for your magnets? Yes, we've offered Demagnetization Curves for our most common Neodymium magnet grades right here. 10.Will my neodymium magnets lose strength over time? Very little. Neodymium magnets are the strongest and most permanent magnets known to man. If they are not overheated or physically damaged, neodymium magnets will lose less than 1% of their strength over 10 years - not enough for you to notice unless you have very sensitive measuring equipment. They won't even lose their strength if they are held in repelling or attracting positions with other magnets over long periods of time. carton
Rare earth samarium cobalt magnets, shorted as SmCo rectangular magnet, are a type of powerful permanent magnet made from the basic elements samarium and cobalt and other metal rare earth materials by mixing, melting, grinding, pressing and sintering. They come in various sizes and shapes, like disc,bar, ring, arc,block, etc.,. Similar to neodymium strong magnets, they belong to the rare earth magnet category, and tcan be classified as SmCo5 and Sm2Co17 according the composition ratios of samarium and cobalt. In comparison to neodymium rare earth magnets, although samarium cobalt magnets may not have as strong magnetic force, they possess two distinct advantages. Firstly, they operate effectively within a higher temperature range, and secondly, they exhibit greater resistance to corrosion. Due to these characteristics, large smco block magnets are commonly employed in applications that demand high operating temperatures, such as generators, pump couplings, sensors, electric motors, marine applications, as well as in the automotive, racing, aerospace, military, and food and manufacturing industries. SmCo rare earth magnets not only perform well at high temperatures but also maintain their magnetic properties even in temperatures below absolute zero (-273 degrees Celsius), making them popular for use in low-temperature applications.
