Introduction to The Axial Flux Motor Rotor Assemblies
Electric motors can be categorized into axial flux and radial flux types based on the direction of magnetic flux. Axial flux motors are characterized by magnetic flux flowing parallel to the axis of rotation. Interestingly, the world’s first motor, invented by Michael Faraday in 1821, was an axial f

Introduction to Frameless Torque Motor Rotor Assemblies
Frameless torque motors are direct drive solutions engineered to deliver high torque without requiring gearboxes or belts. Unlike housed motors, they come as separate stator and rotor subassemblies that can be embedded directly into the target system. By eliminating frames, bearings, and other bulky

What Are Resolvers?
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

Still Concerned About Overheating Issues with Traditional Magnetic Steels? Consider SDM Anti-Eddy Current Magnetic Steel ForEnhanced Thermal Performance, Cost Efficiency, And Extended Service Life! 
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

What Is The Principle Behind Magnetic Coupling? A Video Explains It All.
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

Magnetic Couplings Enable Power Transmission without Direct Contact.
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
