Based on this, the detection method and device of rotor are embodiments provided, is carried out below by embodiment
Description.
Embodiment 1
The detection method of the rotor proposed referring to Fig. 1, the present embodiment specifically includes 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
It is front also to include：
Hall element is installed in motor, wherein, the quantity of Hall element is more than a set of.
Hall element is a kind of Magnetic Sensor based on Hall effect, and Hall element can use various semi-conducting material manufacturings,

Many advantages, small volume, lightweight, easy for installation, small power consumption, are not afraid of dust, greasy dirt, steam and salt fog etc. at frequency height, vibration resistance
Pollution or corrosion.The high precision of Hall linear unit, the linearity are good, Hall switch device is contactless, without abrasion, output waveform
Clearly, non-jitter, without rebound, positional repeatability high (up to μm level).Employ the Hall device of various compensation and safeguard measure
The operating temperature range width of part, reachable -55 DEG C～150 DEG C.
Multiple positions for installing Hall element are set before Motor Production Test, so as in permanent magnetism without generator in carry out
Use.In the present invention, the quantity of the Hall element for arranging in motor can be carried out flexibly according to the use scene of motor by user
Setting, but to be ensured the quantity of Hall element more than a set of.Afterwards, motor is arranged in dynamical system.
Driver and motor are attached, and each set Hall element configuration label, here, label are respectively by driver
Correspond with the quantity of the Hall element installed in motor.Each set Hall element is carried out by 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 occurred
Failure, i.e., can not normally detect the particular location of motor rotor in operation process.
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) matched with motor, that is, specify the normally functioning Hall element to detect the position of rotor,
Afterwards, by driver drives motor rotation.By the method for this segment description so that driver is operated in motor
Before, it is ensured that with the presence of normal Hall element in motor, it is to avoid the motor situation that electricity cannot operate on occurs.
Step S102：As motor in normal operation has and only a set of normal Hall element is being acted 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
The output voltage of the every other Hall element beyond dynamic device detection is currently used.
Step S103：When detecting in the presence of output voltage is not all high level/low level Hall element, that is, operate
When also there is normal Hall element in motor, the ordinary Hall element for detecting is matched by driver with motor, by
The ordinary Hall element takes over current Hall element, to detect the rotor-position of motor.During practical application, the transfer process can
To accomplish to be seamlessly connected, i.e., it is capable of achieving by changing automatically some of driver flag bit, therefore, although, Hall element
Converted, but still ensured that motor is run well.
Additionally, this method also includes：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 motor, in such manner, it is possible to be prevented effectively from motor because
To rotate the abnormal damage for causing.
In the above-mentioned methods, when the output voltage for detecting Hall element is high level/low level, driver is generated
Label corresponding with abnormal signal is also sent to master controller by abnormal signal, driver, after master controller receives label, is shown
The position of the corresponding Hall element of indicating number, at this moment, is easy to staff to be checked and safeguarded.
In another case, when the output voltage for detecting a Hall element is high level/low level, drive
Dynamic device generates abnormal signal, and label corresponding with abnormal signal is also sent to master controller by driver, and master controller is received
To after label, the position of the corresponding Hall element of label is shown, to notify that staff is safeguarded in time.
As motor is carried in power-equipment, also, the equipment of power resources can be provided for which.Most power set
The standby meeting drive motor during operating is rotated together.Therefore, if installing multiple motors in power-equipment additional, to protect
When the Hall element of one motor of barrier is damaged, the design that power resources are provided by another motor is unpractical, and reason exists
In, cost is not only increased, and, the heavy burden of whole power-equipment can also increased, the efficiency of its operating is reduced.
The present invention proposes and many set Hall elements is arranged in motor, it is preferred that in the detection method of this rotor
Hall element is set to two sets.So, the normal operation of motor had both been ensure that, the heavy burden of motor and power-equipment can have been reduced again,
Efficiency is taken into account.
In sum, the detection method of the rotor that the present embodiment is provided includes：Worked as by driver real-time judge motor
Whether the output voltage of the front Hall element for using is high level/low level, if it is, showing currently used Hall element
Break down, then the output voltage of all Hall elements beyond driver detection is currently used, when detecting output voltage
In the presence of being not all high level/low level Hall element, the Hall element for detecting is matched by driver with motor, and
Continued to detect the rotor-position of motor by the Hall element, so, during motor rotation, will not be because of a set of Hall
The damage of element and stop running well, so as to increased the time of the normal operation of motor, improve the operating efficiency of motor.
