Principle of rotating electromagnet

A rotating electromagnet is simply a high-precision actuator in which the electromagnetic coil is energized to generate a magnetic field that rotates the mandrel in the middle of the electromagnet. The general structure can be divided into four kinds: magnetic steel Angle rotating electromagnet, steel ball Angle rotating electromagnet, fan Angle rotating electromagnet, bevel Angle rotating electromagnet. We will separate the four structures of rotating electromagnets and introduce the principle and performance one by one.

1 Magnetic steel rotating electromagnet: The structure contains special coil, permanent magnet, rotating shaft, wire, bearing, electronic components and so on. Magnetic stiffness Angle electromagnet structure is complex, the highest processing precision, the advantage is that the rotation Angle can be made into 90° and 180° and automatic reset, rotation speed is fast, mainly used for high precision mechanical equipment and medical instruments, the disadvantage is that the rotation force is small, high cost!

2 Steel ball Angle rotating electromagnet: The structure contains electromagnetic coil, steel ball, rotating shaft, bearing, wire, electronic components and so on. The steel ball Angle is compact, and the rotation Angle can be selected from 25°-90°. It has the socket coil spring return, and the rotation force is large. It is widely used in sorting equipment, automation equipment, medical instruments and testing equipment, etc.

3 Fan Angle rotating electromagnet: The structure contains electromagnetic coil, rotating shaft, bearing, wire, electronic components and so on. The use of technology imported from Germany, clever structure to avoid friction between machinery, greatly improve the performance and life of the electromagnet. Applications: Sorting equipment, automation equipment, automobile, packaging machine, medical equipment, etc.
