Abstract
A ferromagnetic transformation induction linear motor (magnetic suspension power unit) is characterized in that a rotor or a stator adopts one or more metal induction rings capable of opening and closing to lead the change of repulsion and attraction between the primary ring and the secondary ring, i.e. the rotor or stator can finish moving or rotating, stopping or braking through the simple opening and closing. The invention can be applied to the motor manufacture, magnetic suspension power and transportation and transmission tool.
Description
Relate to the field
Motor manufacturing, linear electric motors application, magnetcisuspension power and communications and transportation, tool for transmitting.
Background technology
Motor is being played the part of very important part as one of sign of progress of modern society in the productive life various aspects, and we can say without motor does not have industry.But motor is also constantly upgrading variation, New-type electric machine is along with the development of electrotechnics, magnetic material etc. also presents the variation of specifications and models, and the variation of use aspect is though ten thousand become not from wherein, all be the application of electromagnetic induction principle, but it is in the difference to some extent of should going up still of principle.The present invention is exactly with the comprehensive new design that is applied to linear electric motors and magnetcisuspension power set of electromagnetic induction principle.
Goal of the invention
A kind of ferromagnetic transformation induction linear motor (magnetic suspension power unit) is provided, and it is applied in departments such as industry, traffic, and the bigger effect of performance.
Summary of the invention
With general motor and magnetcisuspension similarity be: ferromagnetic transformation induction linear motor (magnetic suspension power unit) of the present invention all is to have used electromagnetic induction---mutual inductance is as the motive force of motor operation and magnetcisuspension; Difference is: ferromagnetic transformation induction linear motor (magnetic suspension power unit) of the present invention has been used the electromagnet principle simultaneously, and, solve mutual inductance by an actuating mechanism or parts and repel---the conversion that electromagnet attracts.This mechanism is the crucial part of the present invention, and constituted the core that the present invention is referred to as ferromagnetic transformation induction linear motor (magnetic suspension power unit) by this device.This mechanism or parts promptly are the induction ring sets of the electromagnetic induction part of the motion of motor and magnetcisuspension power or promotion.Under the effect of the primary magnetic field of alternating current or variation, when the induction ring set was in closure state, promptly ring set self constituted the loop, and inductance loop puts generation short circuited inductance electric current, and inductive means (comprising its iron core) is to elementary generation repulsive interaction; Under the effect of alternating current, direct current or variation, constant primary magnetic field, when the induction ring set was in open state, promptly ring set self did not become the loop, and ring set does not produce any induction, inductive means (comprising its iron core) does not only produce repulsion to elementary, is subjected to elementary attraction on the contrary.By such one can opening---closed ring set makes linear electric motors of the present invention and magnetcisuspension power set to have possessed two kinds of absolutely different functions simultaneously under the situation that other conditions do not change.This also just make linear electric motors of the present invention and magnetcisuspension power set no matter as stator still as mover, all possess can stop by very simple disconnection---closed action is moved, transmission---, brake operating.In like manner, the number by increasing ring set or to ring set disconnection---closed degree is carried out incremental operation, obtain induction short circuit current, the induct reverse magnetic repulsion and the electromagnetic actuation power of classification or stepless adjustment, different sizes.

When Δ=0, collar closure under the primary magnetic field influence, produces the short circuit current of inducting in the ring set, and secondary and elementary iron core repels mutually;
When Δ＞0, the collar disconnects, and does not have the electric current of inducting in the ring set, and secondary iron core becomes the path of primary magnetic field, elementary and secondary attracting each other.
