Abstract

Disclosed is a system for detecting working distribution angles of Hall sensors of an outer-stator type two-phase direct-current motor. The system is a detecting and commanding signal system which is necessary for converting brush reversing power supply adopted in the inner-rotor and outer-stator type direct-current motor with the application number of 02125853.8 into electronic controller reversing power supply. A controller receives signals of the four Hall sensors, then the position of a rotor of the motor and the reversing power supply time can be determined, and therefore the motor can operate for a long time with a large current and a high voltage and will not be limited when applied to daily life.

Description

The Hall element work distribution angle of outer stator type two-phase DC motor

The Hall element work distribution angle of outer stator type two-phase DC motor.Technical field: the present invention is installed in application number to be: a kind of signal in 021258538 motor receives and sends device, it is 021258538 outer stator type two-phase DC motor by application number, use in the past brush work, make now electronic controller powered operation into, this motor is used electronic controller powered operation instead, the signal that just must have Hall element to send, commands controller to power on time to motor, and detects the rotating speed of motor.A motor has two kinds of working methods, and one has overlapping work, another kind while being two-phase exchange be the not overlapping work of two-phase exchange; What required power was very large just must exchange overlapping work by two-phase.Driving force motor on picture electric automobile, its power is powerful, just must two-phase exchange overlapping work, if brush-commutated power supply, be exactly that two overlaid work are all not all right, because brush-commutated powered operation, as long as voltage has a hectovolt, electric current has 100 peaces, the spark that commutator commutation copper electrode on motor and brush produce, have more than is neededly will burn out for a long time, just can not normal power supply after burning out, motor also just can not be worked for a long time, make Hall element into, catch and make commutation power-on time, send power supply signal to electronic controller exactly, work long hours can be not bad for motor like this, make this motor not only at electric automobile, on the various vehicles such as train, well applied, and can replace three-phase alternating-current motor completely, in daily life, the various fields that use.

Outer stator type two-phase DC motor, a kind of motor of the inventor in the DC motor of patent application utility model patent on the 18th in December calendar year 2001, again applied for patent of invention on July 30th, 2002, application number is: 021258538, and denomination of invention is: the direct electromotive force machine of inner-rotor-type and outer stator type; When this machine operation, electric current passes through once from coil, just there are mutual suction, mutual exclusion and three kinds of power of electrical power to do work simultaneously, this is no matter in existing all motor, or in physics, is the motor not having, and it is energy-conservation up to more than 30 percent, that is to say that electric current takes advantage of voltage can only calculate this power input to a machine, cannot calculate the power output of this motor, the power stage computing formula of this motor, also among research.

Summary of the invention: because application number is: 021258538 outer stator type DC motor, in the time using brush-commutated powered operation, electric current greatly, high voltage operation, otherwise just burn out commutator, the application of this motor is restricted, so, must make electronic controller powered operation into, the inventor invents again the distributing position of this motor Hall Plate transducer like this, be used for responding to the accurate power-on time that spreads out of motor, make electronic controller receive the power supply signal that transducer spreads out of suddenly, on time power supply.Outer stator type two-phase DC motor, it points two, four, six, eight, etc. a lot of magnetic poles; But it is no matter how many magnetic poles, all only with four transducers, are respectively H1, H2, H3, H4; H1 and H3 are the work induced signals that sends a phase, and H2 and H4 are the work induced signals that sends an other phase, they are all in a concentric circumference, radius is all identical, the data of radius are to determine according to Hall magnet steel, when regulation Hall magnet steel rotates, transducer H1, H2, H3, H4 must can be covered.Transducer H1, H2, H3, the H4 distribution angle in concentric circumference, according to the not overlapping work of motor of four magnetic poles of two-phase, H1 and H2 are 45 degree, and H2 and H3 are 180 degree, and H3 and H4 are 45 degree; When overlapping work, as long as make H2 and H3 into 107 degree between 100 the Seventh Five-Year Plan degree, the angle between other transducer is constant.

According to the motor of six magnetic poles of two-phase, not overlapping work, H1 and H2 are 30 degree, and H2 and H3 are 120 degree, and H3 and H4 are 30 degree; When overlapping work, as long as make H2 and H3 into 110 degree between 115 degree, the angle between other transducer is constant, as figure.According to the motor of eight magnetic poles of two-phase, when not overlapping work is rotated, H1 and H2 are 22 five degree, and H2 and H3 are 90 degree, and H3 and H4 are 22 five degree; When two overlaid work, H2 and H3 will make 80 degree between 85 degree, and the angle of other transducer does not change.

According to the motor Hall element of four, six, eight magnetic poles of above two-phase, the distribution angle of H1, H2, H3, H4 is to have certain regularity, be exactly 360 deg divided by the quantity of magnetic pole again divided by two, it is the angle of H1 and H2 and H3 and H4, the angle of H2 and H3 is the summation of the angle of two magnetic poles, wanting two overlaid work is exactly that the summation of two magnetic poles subtracts ten degree, can in any one angle subtracting in ten degree.So there is above rule, outer stator type two-phase is from the sensor location of the DC motor of two, four, six, eight, ten etc. a lot of magnetic poles, and I just need not all write out, need only do according to above rule just passable.
