The position of rotor in element real-time detection motor, to complete the commutation of motor.But since Hall element is vulnerable part, so
Once Hall element cisco unity malfunction (for example, Hall element damage etc.), that driver can not be known in motor operation course
Know motor rotor-position, also just can not driving motor operated.
Based on this, the embodiment of the invention provides the detection method of rotor and devices, carry out below by embodiment
Description.
Embodiment 1
Referring to Fig. 1, the detection method of the rotor that the present embodiment proposes specifically includes the following steps:
Step S101: whether the output voltage of the currently used Hall element of driver real-time judge motor is high electricity
Flat/low level.
The output voltage of the currently used Hall element of driver real-time judge motor whether be high level/low level it
Before further include:
Hall element is installed in motor, wherein the quantity of Hall element is greater than a set of.
Hall element is a kind of Magnetic Sensor based on Hall effect, and Hall element can use a variety of semi-conducting material manufacturings,
Such as Ge, Si, InSb, GaAs, InAs, InAsP and multi-lager semiconductor heterojunction structure quantum-well materials.Hall element, which has, to be permitted
More advantages, small in size, light-weight, easy for installation, small power consumption, frequency height, vibration resistance are not afraid of dust, greasy dirt, steam and salt fog etc.
Pollution or corrosion.The precision of Hall linear unit is high, the linearity is good, and Hall switch device is contactless, without abrasion, output waveform
Clearly, non-jitter, high (up to μm grade) without rebound, positional repeatability.Using the Hall device of various compensation and safeguard measure
The operating temperature range of part is wide, and reachable -55 DEG C~150 DEG C.
Set before Motor Production Test it is multiple for installing the positions of Hall element, so as in permanent magnetism without being carried out in generator
It uses.In the present invention, the quantity for the Hall element being arranged in motor can be carried out by user according to the usage scenario of motor flexible
Setting, but it is a set of to guarantee that the quantity of Hall element is greater than.Later, motor is mounted in dynamical system.
Driver and motor are attached, and are respectively that each set Hall element configures label, here, label by driver
It is corresponded with the quantity for the Hall element installed in motor.Each set Hall element is subjected to area by the difference of label
Point.
Before motor starts running, the output voltage of each set Hall element is detected by driver.Because working as Hall element
Output voltage when being high level (output voltage of some Hall elements is low level), show that Hall element has already appeared
Failure cannot normally detect the specific location of motor rotor during operation.
When the output voltage of all Hall elements is not all high level/low level, that is, show presence in this motor just
Normal Hall element, then, in this case, output voltage is not all high level/low level Hall element (i.e. by driver
Normally functioning Hall element) it is matched with motor, that is, the position for specifying the normally functioning Hall element to detect rotor,
Later, it is operated by driver driving motor.By the method for this segment description, so that driver is operated in driving motor
Before, guarantee to avoid in motor with the presence of normal Hall element motor once powering on the case where can not operating appearance.
Step S102: since motor has in normal operation and only a set of normal Hall element is acting as
With.At this moment, if it is judged that the output voltage of currently used Hall element is high level/low level, then, at this moment by driving
Dynamic device detect it is currently used other than every other Hall element output voltage.
Step S103: it in the presence of detecting that output voltage is not all high level/low level Hall element, that is, operates
There is also when normal Hall element in motor, the ordinary Hall element that driver will test is matched with motor, by
The ordinary Hall element takes over current Hall element, to detect the rotor-position of motor.When practical application, which can
To accomplish to be seamlessly connected, i.e., can be realized by changing certain flag bits in driver automatically, therefore, although, Hall element
It is converted, but still ensures that motor runs well.
In addition, this method further include: when the output voltage of all Hall elements is high level/low level, i.e. motor
When interior all Hall elements are all in malfunction, driver stop driving motor, in such manner, it is possible to effectively avoid motor because
To be damaged caused by rotation exception.
In the above-mentioned methods, when the output voltage for detecting Hall element is high level/low level, driver is generated
Abnormal signal, label corresponding with abnormal signal is also sent to master controller by driver, after master controller receives label, is shown
At this moment it checks and safeguards convenient for staff in the position of the corresponding Hall element of indicating number.
In another case, it when the output voltage for detecting a Hall element is high level/low level, drives
Dynamic device generates abnormal signal, and label corresponding with abnormal signal is also sent to master controller by driver, and master controller receives
To after label, the position of the corresponding Hall element of display label, to notify staff to safeguard in time.
Since motor is load in power-equipment, also, the equipment of power resources can be provided for it.Most power are set
It is rotated together for will drive motor during operating.Therefore, if installing multiple motors additional in power-equipment, to protect
Hinder a motor Hall element damage when, provided by another motor power resources design be it is unpractical, reason exists
In not only increasing cost, moreover, the weight bearing of entire power-equipment can also increased, reduce the efficiency of its operating.
The invention proposes more set Hall elements are arranged in motor, it is preferred that in the detection method of this rotor
Hall element is set as two sets.In this way, not only ensure that the normal operation of motor, but also the weight bearing of motor and power-equipment can be reduced,
Efficiency is taken into account.
In conclusion the detection method of rotor provided in this embodiment includes: to be worked as by driver real-time judge motor
Whether the output voltage of the preceding Hall element used is high level/low level, if so, showing currently used Hall element
Break down, then driver detect it is currently used other than all Hall elements output voltage, when detecting output voltage
It being not all in the presence of high level/low level Hall element, the Hall element that driver will test is matched with motor, and
The rotor-position of motor is continued to test by the Hall element, in this way, during motor operating, it will not be because of a set of Hall
The damage of element and stop running well, thus increase motor normal operation time, improve the working efficiency of motor.
