How to Choose Speaker Magnets? We all know that the speaker inside the speaker equipment, is responsible for the core important parts of the sound, the speaker is a transducer device that converts electrical signals into acoustic signals. The performance of the speaker has a great impact on the sound quality. What is a speaker [...]
Poles Number of Motor Rotor and Stator Magnet What is the relationship between the number of motor stator poles and rotor poles? Many friends may not know, in fact, it is not difficult to understand, there is a relevant foundation of friends will understand at a glance, the following courage magnet manufacturers to take you [...]
Working Principle Of Motor Stator Magnet The stator in a motor is the stationary part, which usually contains winding coils or permanent magnets responsible for generating the magnetic field, the working principle of motor stator magnets is based on electromagnetic induction and magnetic field interaction. Types of MOTOR stator magnets; The main types are electromagnetic [...]
Recycling Method of Sintered NdFeB Magnet Waste The waste recycling of NdFeB materials is usually divided into two directions: one is to separate and extract various elements, especially rare earth elements, in the NdFeB waste to prepare oxides or other compounds with a certain purity, which can be used as raw materials for different applications. [...]
Adhesive strong magnet is powerful Neodymium magnet with high quality 3M adhesive backing and a new, easy-pull tab. The neodymium magnet is Ni-Cu-Ni plated to protect them against corrosion and conventionally magnetized through the thickness. Usually, the magnets exist in two versions per size – the A version has a North Pole face visible; the [...]
Neodymium Motor Magnet is available, it is mainly used in automatic control system and long range linear motion device, we are offering the length 100 - 700mm. Neodymium magnet is widely used in magnetic motor and vehicle magnet applications, it is typically two to three times stronger than ferrite magnet, which results in greater performance [...]
Magnetic Pot Round Base Magnet are ceramic or neodymium magnets clad with a steel cup. Magnetic strength can be multiplied with the block of the steel cup, These magnets are often found in applications requiring a strong holding device or the ability to attach a post or hook to hang inspection equipment, indicator gauges, lamps, [...]
IPM vs SPM Electric Motors A PM motor can be separated into two main categories: surface permanent magnet motors (SPM) and interior permanent magnet motors (IPM) . Neither motor design type contains rotor bars. Both types generate magnetic flux by the permanent magnets affixed to or inside of the rotor. SPM motors have the magnets [...]
Difference Between Inline and Surface Mount NdFeB Magnets in PM Motors What is the difference between inline and surface mount design of NdFeB magnets for permanent magnet motors? A permanent magnet (PM) motor is a type of AC motor that uses permanent magnets embedded or attached to the surface of the motor rotor. Electric vehicles [...]
Effects of Magnetic Parameters on Permanent Magnet PM Motors How to measure the magnetic properties of magnet? Almost all magnet manufacturers use B-H curve testing equipment to get the demagnetization curve of magnet. This method is a closed circuit measurement, and an uniform cross-section sample is clamped between the faces of electromagnet. The testing sample [...]
Permanent Magnet Motor Operation Tips Key technical points for maintaining normal operation of permanent magnet motors Once the permanent magnet motor is demagnetized, basically the only option is to replace the motor; the cost of repair and a large amount of how to determine the permanent magnet motor demagnetized it, we go on to see. [...]
The “Center” of Permanent Magnet Motors – Permanent Magnets The development of permanent magnet motors is closely related to the development of permanent magnet materials. China is the first country in the world to discover the magnetic properties of permanent magnetic materials and apply them to practice. More than 2000 years ago, China made a [...]
