Resolvers are a type of rotary electrical transformer or sensor used to measure the angular displacement and speed of rotating objects. They are analogue devices that have digital counterparts. Many resolvers look somewhat like an electric motor, comprising copper windings on the stator and a machin

Permanent magnet (PM) motors are a type of electric motor that uses permanent magnets for field excitation. Using permanent magnets for excitation not only reduces power consumption, achieving energy savings, but also enhances the operational performance of motors. PM motors are one of the largest a

Please observe! This ordinary iron rod, when positioned within a coil, rapidly heats up and begins to emit smoke! Remarkably, when a human hand is placed in the same coil under identical conditions, no such reaction occurs. What's the scientific principle underlying this seemingly paradoxical phenom

If the large rotary crusher were to become jammed during operation, it could potentially result in damage to its motor. Similarly, in the case of a chemical agitator, its propeller is connected to the motor through a shaft. If the shaft seal were to leaks, the resultant chemical spill could potenti

Pay attention: These two half-couplings transfer power without any physical contact between them. This is the Axial Magnetic Coupling, a device that transmits torque through magnetic fields.No openings required, non-contact transmission, and leak-proof.Another type is our Radial Magnetic Coupling, h

High-speed motor rotors can operate at tens of thousands or even over one hundred thousand of revolutions per minute. Such extreme operational conditions impose rigorous requirements on each component. So, how does SDM succeed in developing high-quality high-speed motor rotors?Fully Independent Magn

Before your eyes is the critical magnetic component of high-speed motors—the high-speed motor rotor. It finds extensive applications in high-end equipment such as aerospace high-speed motors, motorized spindles, medical magnetic levitation pumps, and high-voltage high-speed motors.Today, we step int

Are you still encountering challenges with underperforming magnetic components? In this discussion, we will explore an innovative magnetic component solution – the Halbach Array!Halbach Array magnets, also referred to as Halbach Permanent Magnets, feature a distinctive magnetic configuration that e
