Abstract

The invention discloses an external control permanent magnetism pole-changing motor. The external control permanent magnetism pole-changing motor comprises 1. excitation coils, 2. an annular magnetizer, 3. a stator coil, 4. an N external permanent magnet 1, 15. an S external permanent magnet 2 and 14. an active magnetic control system lidesheng. The internal control information in 14. the active magnetic control system lidesheng is respectively output through 9. a control port 1 for the active magnetic control system lidesheng, and is output through 7. an input port 1 and 13. a control port 2 for the active magnetic control system lidesheng, and supplies power for 1. the excitation coils through 10. an input port 2; as the 1. excitation coils obtain power, an N/S changeable heteropolarity magnetic field is generated; a 3. stator coil is cut by the changeable heteropolarity magnetic field generated from the 1. excitation coils and the permanent magnets; and cutting and driving of magnetic field is generated as the stator coil is influenced by cutting of magnetic line by the permanent magnets so that speed adjusting and driving can be realized by means of reverse cutting and driving of magnetic field.

Description

External control permanent magnet pole-change motor

Technical field

The present invention relates to the external control magneto pole-changing technology of the multi-field purposes such as a kind of excitation pole-changing, particularly relate to a kind of outer ring magnetic conductor that utilizes to control the device of excitation wire bag size of current; Drive motors and and the device of regulating the speed at any time (being called for short " external control permanent magnet pole-change motor ") is utilized with electric motor car, motor, flying object, locomotive etc.

Background technology

Current motor is all with the curtage of online direct main control line bag and frequency, and be that master is made up of electronic devices and components with frequency converter, components and parts easily burn by big current and overload, have direct correlation easily to damage with ambient temperature, humidity; Frequency converter is online variable mode, and product cost is high; The motor price of frequency converter and this power is close and higher.

Summary of the invention

The present invention be directed to the deficiencies in the prior art and a kind of external control type permanent magnet pole-change motor technology is provided.

The problem that the present invention solves: motor and electric tool and electric equipment automatic speed regulation; Firing current is little contributes to energy-conservation and speed stabilizing; Reduce electrical fault, reduce product cost.

Principle of the present invention: according to electric magnetisation principle, utilizes line bag around outer ring magnetic conductor excitation magnetic field, and line bag electric current regulates excitation and rotor synchronous rotary and interior permanent magnet to produce closing of cutting magnetic field as required; The outer permanent magnet 1 of 3.N and the outer permanent magnet 2 of 15.S synchronously produce cutting rotating magnetic field for magnet structure; Utilize cutting magnetic field to complete oneself to rotate, the size of cutting magnetic field can regulate arbitrarily.

The moment of torsion N m=9550* power/rotating speed of motor, i.e. torque T=9550*P/n, power P=T*n/9550.Torque unit is Nm(ox rice); P is specified (output) power unit of motor is kilowatt (KW); Rated speed n unit turns per minute (r/min).

Regulate the power output of 450VA excitation wire bag size of current=change 40 kilowatt motors=change 40 kilowatt motor cutting magnetic field size=change actuating speed and moments of torsion.

40 kilowatt motors: braking maximum consumption exciting power=450VA.

Reactive magnetron system features: excitation I size of current and magnetic field intensity electrodeless adjustable.

Structure of the present invention comprises: permanent magnet 2 etc. in permanent magnet 1, N/S magnetic pole, cutting magnetic line direction 1, input port 1, rotor direction of rotation, reactive magnetron system lidesheng control port 1, input port 2, magnetic line of force direction 2, S/N magnetic pole, reactive magnetron system lidesheng control port 2, reactive magnetron system lidesheng, S in excitation wire bag, outer ring magnetic conductor, stator line bag, N.

Jointly external control permanent magnet pole-change motor is formed with outer the permanent magnet 2 and 14. reactive magnetron system lidesheng of 15.S etc. by 1. excitation wire bags and 2. outer ring magnetic conductors and 3. stator line bags and the outer permanent magnet 1 of 4.N.

The built-in control information of 14. reactive magnetron system lidesheng is exported to be exported by 7. input port 1 and 13. reactive magnetron system lidesheng control ports 2 through 9. reactive magnetron system lidesheng control ports 1 respectively and is powered to 1. excitation wire bags by 10. input ports 2, 1. what excitation wire Bao get electricity generation N/S was variable has polarity magnetic field, 1. contract for fixed output quotas raw variable have polarity magnetic field and permanent-magnet synchronous of excitation wire cuts 3. stator line bags, 3. stator line bag produces cutting driving magnetic field by permanent magnet cutting magnetic line, reverse cut driving magnetic field is utilized to realize the object of governing speed and driving.
