In modern industrial automation and precision mechanical control, accurate rotational position detection is crucial. The reluctance resolver, commonly referred to as a resolver, is a highly reliable sensor widely used in servo motors, robotics, and other applications requiring precise positioning. T

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
