Control.For example, in the design value 0.5A relative to overcurrent limits value and the measured value of overcurrent limits value deviates to 0.45A's
In the case of, by the way that reference voltage V 2 is modified to 0.55V from 0.5V, the measured value of overcurrent limits value is corrected to 0.5A.
The fluctuation (such as ± 10%) of the offset of reference voltage V 2, the sluggishness of comparator 515a or comparator 515a is compared
The resistance value of the resistance R3 of overcurrent detection fluctuates (such as ± 1%) greatly, therefore can be 2 pairs by adjusting reference voltage V
The major part of overcurrent limits value fluctuation is modified.
Variation
Figure 10 is the block diagram of the structure for the control unit 51a for showing the motor involved by variation.For control unit 51a,
Relative to the control unit 51 in the motor 100 involved by embodiment 1, the selection control of 514 ground of multiplex adapter is not only used
Signal SG1 or this structure of control signal SG2 are different, and control unit 51a can be applied to the motor involved by embodiment 1
Control unit 51 in 100.
The conducting wire 10 being connect with control unit 51a branches into this two parts of conducting wire 10a and conducting wire 10b, conducting wire 10a and motor control
The port in portion 511 processed connects, and conducting wire 10b is connect with the port of communication unit 512.Motor control part 511 and communication unit 512 are distinguished
It is connect with voltage monitoring portion 513 by signal wire.
Voltage monitoring portion 513 is detected the voltage that power transistor IC4 is applied to from high voltage power supply.Just as first
When an example, detected voltage be predetermined threshold value more than in the case of, will action stop signal SG8 to
Communication unit 512 is sent.As an example of the second timing, the case where detected voltage is less than predetermined threshold value
Under, action stop signal SG8 is sent to motor control part 511.In addition, predetermined threshold value refers to：Than being estimated as turning
The also small voltage value of fluctuation minimum value for the voltage value for being applied to power transistor IC4 or stator 3 during 1 rotation of son.
That is, during rotor 1 rotates (such as first timing), action stop signal SG8 is sent to communication unit 512,
The action of communication unit 512 stops.On the other hand, during the action of motor control part 511 stops (such as second timing),
Action stop signal SG8 is sent to motor control part 511, and the action of motor control part 511 stops.
Conducting wire 10 will control signal SG1 (the first signal) to 5 (specifically control unit of microcontroller in the first timing
51) it transmits, will control signal SG2 (second signal) in the second timing passes to microcontroller 5 (specifically control unit 51a)
It is defeated.That is, control unit 51a receives control signal SG1 via conducting wire 10 and in the first timing, control signal is received in the second timing
SG2。
As a result, during rotor 1 rotates, communication unit 512 can not be made to act and be written to the data of storage part 52
Processing, it is thus possible to prevent the mistake write-in of data caused by the influence of noise generated during rotor 1 rotates.
In addition, being connected with the filter for the filtering for carrying out control signal SG1 between conducting wire 10a and motor control part 511
516a (first filter) is connected with the filter for the filtering for carrying out control signal SG2 between conducting wire 10b and communication unit 512
516b (second filter).
In addition, the time constant of filter 516a is more than the time constant of filter 516b.The reason for this is that：For filter
The time constant of 516a is set larger, such as be set as 10 μ s to remove the noise generated during rotor 1 rotates,
But during communication unit 512 acts, if time constant greatly if communication speed reduce, therefore, the time constant of filter 516b
It is set smaller, such as is set as 16ns.
Also, it is smaller than the voltage value for being applied to power transistor IC4 from low-tension supply by being set to threshold value, such as set
It is set to 13.5V, can prevents from leading to low-tension supply in the failure etc. of device (such as air conditioner) side because carrying motor 100
What is generated in the case of enter (return to り Write む) to high voltage power supply is written to the mistake of storage part 52.
In addition, conducting wire 10b shows one in Fig. 10, but it may be two.The case where conducting wire 10b is two
Under, such as one in two, the rotation sent from the device for carrying motor 100 is communicated as control signal SG1
Speed command signal, and the timing (clock) sent from the device for carrying motor 100 is communicated as control signal SG2
Another in two, the rotation that the oriented device for carrying motor 100 is sent is communicated as control signal SG1 for signal
Velocity information signal, and as control signal SG2 and with carry motor 100 device intercommunication data-signal.
It is I2C (Inter-Integrated Circuit to control signal SG2：IC bus) communication.
The effect of the motor 100 involved by embodiment 1 is illustrated using Figure 11.
Figure 11 is the block diagram of the structure for the control system for briefly showing the motor 100a involved by comparative example.
Motor 100a involved by comparative example does not have voltage in microcontroller 5a (specifically control unit 51b)
Monitoring unit 513 and multiplex adapter 514 and the connector 30 that there is the conducting wire 10 for transmission of control signals SG1 to connect and confession
Connector 40 this aspect that the conducting wire 20 different from conducting wire 10 connects is upper and embodiment 1 involved by 100 difference of motor, other
Point is mutually the same.That is, the motor 100a involved by comparative example has the connector 30 and 40 exposed in the outside of motor, and
And the conducting wire 20 other than the conducting wire 10 with transmission of control signals SG1 also with the write-in processing to storage part 52.
To the write-in of storage part 52 processing be not the action carried out always, therefore, usual conducting wire 20 not with connector 40
Connection.For example, in the feelings for using the motor 100a involved by comparative example as the fan motor in the outdoor unit of air conditioner
Under condition, there are following misgivings：The attachment of moisture condensation for generating etc., has conducting wire 20 not connected when frost due to removing heat exchanger
Connector 40 inside connector pinout generate rust, to generate to the mistake of storage part 52 write-in, motor 100a shape
Condition is bad.
In motor 100 involved by embodiment 1, as the control data such as program or control parameter to be written
Signal wire and use the conducting wire 10 that can be multiplexed.Thus, it is possible to which transmission to be carried out to the control (rotor 1 of motor 100
Rotation control) when the signal wire (conducting wire 10) of control signal SG1 the control when write-ins of data is handled is carried out as transmission
The conducting wire of signal SG2 uses, therefore is capable of providing in a kind of control may be implemented in motor 100 and the write-in of data processing
The motor 100 for sharing (activation bit is shared with control information) of the signal wire used.
In other words, it need not arrange that the signal wire different from the signal wire of transmission of control signals SG1 (believe by data write-in
Number line), therefore it need not be connected with the connector of conducting wire always, it is capable of providing a kind of motor with involved by comparative example
100a, which is compared, can prevent the signal that the situation of the motor caused by rust of connector etc. is bad and is drawn from motor
The few motor 100 of the quantity of line (conducting wire).It can be from the external signal for carrying out data write-in of motor 100 that is, can reduce
The quantity of line.Thus, it is possible to provide motor 100 with low cost.
In addition, be even connected with the connector of conducting wire always, to expose in the connector of the outside of stator the case where
Under, it is also subjected to the influence of temperature change, therefore the attachment to condense relative to connector pinout can not be entirely prevented.Therefore,
It, can due to the connector without exposing in the outside of stator in motor 100 involved by present embodiment 1
Prevent the situation of the further motor caused by rust of connector etc. bad.
Also, the motor 100 involved by embodiment 1, can from the outside of motor 100 will control program with
And a variety of data such as control parameter are written via signal wire (conducting wire 10) to storage part 52.Thus, it is possible to inhibit along with data
Type, the increases of the components such as signal wire or connector.
Motor 100 involved by embodiment 1, can be by overcurrent limits value and the position of magnetic pole of Hall IC
The control parameters such as the phase deviation of signal are written to storage part 52, thus be capable of providing it is a kind of can to the characteristic of motor 100 into
Capable modified motor 100.As a result, it is possible to reduce the individual of the characteristic of the motor such as moyor, noise, maximum output 100
Difference.
Also, the motor 100 involved by embodiment 1 can write the control parameters such as moyor, advance angle
Enter to storage part 52, therefore is capable of providing the motor 100 for the device (such as air conditioner) for being most suitable for carrying motor 100.Example
Such as, it is capable of providing the big motor 100 of the good motor 100 of moyor, noise few motor 100 or maximum output.
Motor 100 involved by embodiment 1, voltage monitoring portion 513 is based on being applied to power transistor IC4's
Voltage controls the output of multiplex adapter 514, it is thus possible to the weight of storage part 52 during preventing rotor 1 from rotating
It writes.Thus, it is possible to be prevented to storage by the noise that (such as in rotation of rotor 1) generates in the action of motor 100
The mistake in portion 52 is written.
Motor 100 involved by embodiment 1, by making switching from the base of the output of multiplex adapter 514
Quasi- voltage (reference voltage that can carry out the write-in processing to storage part 52), which is less than from low-tension supply, is applied to motor 100
Voltage, can prevent to the mistake of storage part 52 be written.
Motor 100 involved by embodiment 1, in multiplex adapter 514, the filter that is connect with communication unit 512
The time constant of wave device 516b is less than the time constant for the filter 516a being connect with motor control part 511, therefore can improve
Noise margin during the rotation of rotor 1.Further, it is possible to improve communication speed (the processing speed of the write-in processing to storage part 52
Degree).

Rewrite controlling program or moyor or advance angle are (between position of magnetic pole signal and the induced voltage for indicating position of magnetic pole
Phase difference) etc. control parameters.
According to Hall IC 7 to the installation accuracy etc. of substrate 8, sometimes from the output (phase of position of magnetic pole signal of Hall IC 7
Position) it is further offset from from ideal phase deviation (design value).In step s 11, the phase difference between design value is measured
