The rotating solenoid is simply a high-precision executive element that the electromagnetic coil is electrified to produce a magnetic field to make the mandrel in the middle of the electromagnet rotate. The general structure can be divided into four kinds: magnetic steel angle rotating electromagnet, steel ball angle rotating electromagnet, fan angle rotating electromagnet and inclined plane angle rotating electromagnet. Let's introduce the principle and performance of four kinds of rotating electromagnets separately.
1. Magnetic steel angle rotating solenoid: the structure consists of special coils, permanent magnets, rotating shafts, wires, bearings, electronic components, etc. The structure of magneto-rigid angle electromagnet is complex, and the machining precision is the highest. The advantage is that the rotation angle can be made into 90 ° and 180 ° and automatically reset, and the rotation speed is fast. It is mainly used for high-precision mechanical equipment and medical devices, but the disadvantage is that the rotation force is small, and the cost is high!
2. Ball angle rotating electromagnet: the structure consists of electromagnetic coil, ball, rotating shaft, bearing, wire, electronic components, etc. The structure of steel ball angle is compact, and the rotation angle can be selected from 25 ° to 90 ° with spring return. It has large rotation force and wide application. It is mainly used in sorting equipment, automation equipment, medical equipment and testing equipment.
3. Fan angle rotating solenoid: the structure consists of electromagnetic coil, rotating shaft, bearing, wire, electronic components, etc. Using the technology and application imported from Germany, the ingenious structure avoids the friction between the machines, and greatly improves the performance and service life of the electromagnet. Application: sorting equipment, automation equipment, automobile, packaging machine, medical equipment, etc.
