Abstract

The invention discloses an internal control permanent magnet pole-changing motor. The internal control permanent magnet pole-changing motor is composed of an 1 excitation solenoid, an 2 internal I-shaped magnetizer, a 3 stator solenoid, an 4 N external permanent magnet 1, an 15 S external permanent magnet 2 and an 14 active magnetic control system lidesheng. The built-in control information of the 14 active magnetic control system lidesheng is respectively outputted by an 9 active magnetic control system lidesheng control port 1 and outputted by an 7 input port 1 and an 13 active magnetic control system lidesheng control port 2 to supply power to the 1 excitation solenoid through an 10 input port 2. The 1 excitation solenoid is electrified to generate an N/S variable hetero-polarity magnetic field. The variable hetero-polarity magnetic field generated by the 1 excitation solenoid and the permanent magnets synchronously cut the 3 stator solenoid. The magnetic lines of force of the 3 stator solenoid are cut by the permanent magnets to generate a cutting driving magnetic field. The objective of speed regulation and driving can be realized by utilizing a reverse cutting driving magnetic field.

Description

Internal control permanent magnet pole-change motor

Technical field

The present invention relates to the internal control magneto pole-changing technology of the multi-field purposes such as a kind of excitation pole-changing, particularly relate to and a kind ofly utilize interior I-shaped magnetic conductor 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 " internal 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 internal 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, utilize line bag around interior I-shaped magnetic conductor excitation magnetic field, and line bag electric current regulates excitation and rotor synchronous rotary and outer 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: the outer permanent magnet 1 of excitation wire bag, interior I-shaped magnetic conductor, stator line bag, N, 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, the outer permanent magnet 2 of reactive magnetron system lidesheng, S etc.

Jointly internal control permanent magnet pole-change motor is formed by permanent magnet 1 outside I-shaped magnetic conductor in 1. excitation wire bags and 2. and 3. stator line bags and 4.N and outer the permanent magnet 2 and 14. reactive magnetron system lidesheng of 15.S etc.
