The right side of setting magnetite and solenoid interconnection technique device is the N utmost point, and the downside of magnetostatic stone is the N utmost point, and moving magnetite is at the downside in magnetostatic stone magnetic field; The downside outside in the gap of the right side of magnetite and solenoid interconnection technique device between the moving conplane outside of magnetite (or inner side) and adjacent magnetostatic stone, it provides the area in magnetic field to be greater than the gap between adjacent magnetostatic stone; The N utmost point of moving magnetite is at the front end of the direction of motion, moving magnetite in magnetostatic stone magnetic field by positive direction motion, solenoid no power now, moving magnetite is subject to positive direction motoricity in magnetostatic stone magnetic field range not have to affect substantially; When moving magnetite moves to the downside outside in the gap between adjacent magnetostatic stone and the right side of magnetite and solenoid interconnection technique device, the position signalling of the moving magnetite of rotor position detector output, make electric supply installation switch on to solenoid, the position signalling of right side moment of magnetite and solenoid interconnection technique device, make electric supply installation switch on to solenoid, right side moment of magnetite and solenoid interconnection technique device provides the stronger N utmost point, what moving magnetite was now subject to is that positive direction power moves forward, and is not opposite direction power; When moving magnetite leaves the upside outside in the gap between adjacent magnetostatic stone and the right side of magnetite and solenoid interconnection technique device, the position signalling of the moving magnetite of rotor position detector output, makes electric supply installation to solenoid power-off, and N cancels extremely substantially; Now moving magnetite has entered the magnetic field of next magnetostatic stone, continues to be subject to positive direction power, by positive direction motion; The like, moving magnetite is in succession by magnetostatic stone and its gap, and length is got up apart from rectilinear motion;
Magnetostatic stone can be made as two-layer, and same pole is relative, moving magnetite between two-layer magnetostatic stone, can the magnetostatic stone of very large minimizing and moving magnetite between distance and strengthen motoricity; The energising of solenoid constantly and conduction time length by rotor position detector, signal is processed to control afterwards; Owing to having used magnetite and solenoid interconnection technique, reduce the power consumption of solenoid, reduce the weight and volume of device.
4. magnetite and solenoid interconnection technique application apparatus as claimed in claim 1, is characterized in that: magnetite and the application of solenoid interconnection technique on electromagnet apparatus, and electromagnet is a kind ofly to utilize that electromagnetic attraction is handled, the device of hitching machinery; By two solenoids and iron core, formed, at two solenoids and the middle magnetite that increases unshakable in one's determination, in the middle of the iron core of each solenoid, possess less hole, can larger minimizing magnetic field intensity during power-off, can a larger increase magnetic field intensity during energising, its sorrow point is the power consumption that reduces solenoid, reduces the weight and volume of device.
