Secondary width is swung: referring to oscillating motor swing arm in other words 400 to be less than the amplitude of the maximum amplitude of oscillation and carry out reciprocally swinging.
Applicants have found that this is because, so that swing arm has little time to the maximum amplitude of oscillation, being just connected to reversed pulse when frequency is too high
And backswing；It reduces frequency and has reformed into full width swing.
Both the above swing is loading, and when the conditions such as voltage and control pulse frequency are constant, the amplitude of oscillation is with central symmetry
's.
Shake in situ: refer to that oscillating motor swing arm in other words 400 is carried out at a stable position with the small amplitude of oscillation
Reciprocally swinging.In the actual process, it is swung to distinguish shake in situ and time width, the pendulum for being less than full width centrosymmetric to the amplitude of oscillation
It is dynamic, and shift oneself fitting center of energy at the maximum amplitude of oscillation onto and symmetrically swing, it is defined as time width and swings；To shifting at the maximum amplitude of oscillation
Cannot oneself fitting center, swing slightly in situ, be defined as shake in situ.This is because driving energy is small, no matter with
How many frequency drivings are impossible to full width and swing.
Applicant further studies after the above-mentioned several swing forms of swing arm of discovery oscillating motor, find this be by
Caused by the alternating impulse that control unit 300 generates is different.Applicant further thinks deeply, for an oscillating motor, when
It is applied in a specific occasion or when being made into a specific electric appliance, and operating voltage, permanent magnet are (for example, first
Permanent magnet 610, the second permanent magnet 620, third permanent magnet 630 and the 4th permanent magnet 640), swing arm 400 and load be typically also true
It is fixed, it is found by the applicant that at this moment there are several significant parameters for alternating impulse: full width swing minimum pulse width Tb and
Its corresponding frequency Fb, full width swing maximum alternating impulse frequency Fa, play pendulum minimum pulse width Td and its corresponding frequency Fd,
These parameters are illustrated below.
Alternating impulse is made of direct impulse and a corresponding reverse impulse, and the pulse width of alternating impulse refers to
The width of its direct impulse or reverse impulse.For example, an alternating impulse, the positive level of a 2ms, was then followed by 3ms before this
Zero level, thus constitute a complete alternation arteries and veins followed by the zero level of 3ms followed by the negative level of a 2ms
Punching, the pulse width of alternating impulse are the width of its direct impulse or reverse impulse, i.e. 2ms.
It is most put on when control unit 300 swings to swing arm 400 to 200 1 direct impulses of coil or reverse impulse
When width position, there are a smallest pulse widths, and direct impulse/reverse impulse pulse width only in alternating impulse is big
When the smallest pulse width, swing arm 400 can be driven to maximum amplitude of oscillation position, otherwise, swing arm 400
It cannot be driven to maximum amplitude of oscillation position, it is wide which is just defined as above-mentioned full width swing minimum pulse
Spend Tb.Full width swings the corresponding frequency Fb of minimum pulse width Tb, refers to that full width is swung when alternating impulse duty ratio is 100%
And direct impulse/reverse impulse pulse width is equal to the frequency that full width swings minimum pulse width Tb, wherein alternating impulse accounts for
It is empty than referring to that the empty accounting of direct impulse/reverse impulse is 100% for 100%, it is possible to alternation arteries and veins at this time is calculated
The period of punching is 2*Tb, therefore the frequency Fb=1/ (2*Tb) of alternating impulse at this time.
Swing minimum pulse width Tb's when control unit 300 is greater than or equal to full width to 200 1 pulse widths of coil
When alternating impulse, such case of maximum amplitude of oscillation position is swung to every time in addition to there is swing arm 400 when doing reciprocally swinging,
When alternating impulse frequency increases, it is also possible to another situation occur, i.e., in swing arm 400 by the past maximum amplitude of oscillation position of direct impulse
During setting swing, there are no maximum amplitude of oscillation position is reached, reverse impulse has just arrived at this time, so that swing arm 400 is not having
There is arrival maximum amplitude of oscillation position just to start backswing again.At this moment, there are the maximum frequencies of such a alternating impulse, when this
When alternating impulse frequency when being less than or equal to the maximum frequency, swing arm 400 can smoothly reciprocally swinging to maximum amplitude of oscillation position,
When the frequency of alternating impulse is greater than the maximum frequency, then swing arm 400 can not reciprocally swinging to maximum amplitude of oscillation position, i.e. swing arm
Do not swing to also maximum amplitude of oscillation position its will backswing, i.e., be less than the amplitude most substantially put with one and carry out reciprocally swinging
Movement, such a maximum frequency are just defined as above-mentioned full width and swing maximum alternating impulse frequency Fa.
To sum up when the pulse width of alternating impulse >=full width swings minimum pulse width Tb, if 0 < alternating impulse
Frequency≤full width swing maximum alternating impulse frequency Fa, then the form progress reciprocally swinging that swing arm 400 is swung with full width；If full
Width swings frequency≤frequency Fb of maximum alternating impulse frequency Fa < alternating impulse, then the form that swing arm 400 is swung with secondary width into
Row reciprocally swinging.In both cases, defeated no matter how frequency becomes if the pulse width of alternating impulse is constant
Torque out is to maintain stable.
Discussed above is the case where pulse width >=full width of alternating impulse swings minimum pulse width Tb, is begged for again below
Expire the case where width swings minimum pulse width Tb by the pulse width < when alternating impulse.
When the pulse width < of alternating impulse, which expires width, swings minimum pulse width Tb, alternating impulse driving coil 200 is produced
Raw electromagnetic force is not enough to that swing arm 400 is driven to swing to maximum amplitude of oscillation position, while there is also one that swing arm 400 to be enable to swing
Minimum pulse width, only the pulse width of alternating impulse be greater than the minimum pulse width that can be swung, 400 ability of swing arm
Enough to be swung by driving, otherwise swing arm 400 is just parked in original position, because the electromagnetic force that alternating impulse driving coil 200 generates is not
It is enough that swing arm 400 is driven to start to swing, which is defined as above-mentioned rising and puts most scun
Rush width Td；Correspondingly, can be calculated, alternating impulse duty ratio be 100% when from pendulum minimum pulse width Td it is corresponding
Frequency Fd, Fd=1/ (2*Td).
Minimum pulse width Tb, and 0 are swung when the pulse width < for playing pendulum minimum pulse width Td < alternating impulse expires width
When the frequency of < alternating impulse≤frequency Fd, swing arm 400 is carried out in the position stopped originally toward physical pendulum with a very small amplitude of oscillation
It is dynamic, swing arm, which is called, in the form shaken in situ carries out reciprocally swinging.
