Abstract
The present invention relates to a kind of motor intelligent control methods for multifunctional food processing unit, comprising: receives motor gear rotary speed information, motor start-up, multifunctional food processing unit detects motor power (output) and revolving speed simultaneously；Judge whether motor power (output) is more than firm power and motor speed whether within the gear range of speeds simultaneously；If motor power (output) exceeds firm power, the power of motor is reduced by reducing input voltage；If motor speed is lower than the minimum of the gear range of speeds, the revolving speed of motor is improved by increasing input voltage, if motor speed is higher than the peak of the gear range of speeds, reduces the revolving speed of motor by reducing input voltage.The technical effects of the invention are that: intelligent control is carried out in driving power and revolving speed control for common AC motor, make it that big torsion and the power in high revolving speed be kept all to be unlikely to emergent power in safe range in the slow-speed of revolution exceeded and damage, reduces product cost.
Description
Technical field
The present invention relates to a kind of control technologies of food processing apparatus, more particularly to a variety of function such as heating and stirring
The method of motor control of the food processing apparatus of energy.
Background technique
Existing multifunctional food processing unit needs motor high speed to rotate forward when using crushing function, and use is turned over
Need motor low speed and reverse that food is kept not battered down during frying.Common AC motor is due to motor speed or resistance
Rising causes motor power (output) exceeded and is easily damaged motor, rotates forward and low speed and reverse function so cannot meet high speed simultaneously
Requirement.Therefore, existing multifunctional food processing unit uses SRD switched reluctance motor substantially, it is well known that SRD electricity
Motivation compares common AC motor complex process and cost is higher by 2-4 times.
Summary of the invention
The technical problem to be solved in the present invention is that being proposed in place of avoiding the deficiencies in the prior art a kind of for common friendship
Galvanic electricity motivation is improved, and so that its power in the slow-speed of revolution and high revolving speed is all not emergent power in safe range exceeded
And the motor intelligent control method for multifunctional food processing unit damaged.
The present invention solves technical solution used by the technical problem are as follows:
Using a kind of motor intelligent control method of multifunctional food processing unit, comprising the following steps:
1. receiving motor gear rotary speed information, motor start-up, multifunctional food processing unit detects motor power (output) simultaneously
And revolving speed；
2. judge simultaneously motor power (output) whether be more than firm power and motor speed whether the gear range of speeds it
It is interior；
3. continuing to examine if motor power (output) is less than firm power and motor speed is within the gear range of speeds
Survey motor power (output) and revolving speed；
4. reducing the power of motor by reducing input voltage if motor power (output) exceeds firm power；If electric
Motivation revolving speed is lower than the minimum of the gear range of speeds, the revolving speed of motor is improved by increasing input voltage, if electric
Motivation revolving speed is higher than the peak of the gear range of speeds, reduces the revolving speed of motor by reducing input voltage.
Further:
The firm power of motor refers to maximum power when reaching safety requirement temperature rise value when to motor operation.
The firm power of motor is determined and carrying out a large amount of performance test to the motor.
Compared with prior art, the technical effects of the invention are that: this patent for common AC motor driving function
Intelligent control is carried out in rate and revolving speed control, makes it that big torsion and the power in high revolving speed be kept all to pacify in the slow-speed of revolution
It is not that emergent power is exceeded and damages in gamut, reduces product cost.
Specific embodiment
Now elaborate to the embodiment of the present invention.
A kind of motor intelligent control method of multifunctional food processing unit of the present invention, comprising the following steps:
1. receiving motor gear rotary speed information, motor start-up, multifunctional food processing unit detects motor power (output) simultaneously
And revolving speed；
2. judge simultaneously motor power (output) whether be more than firm power and motor speed whether the gear range of speeds it
It is interior；
3. if motor power (output) is less than firm power and motor speed is within the gear range of speeds, motor
It continues working, until task is completed；
4. reducing the power of motor by reducing input voltage if motor power (output) exceeds firm power；If electric
Motivation revolving speed is lower than the minimum of the gear range of speeds, the revolving speed of motor is improved by increasing input voltage, if electric
Motivation revolving speed is higher than the peak of the gear range of speeds, reduces the revolving speed of motor by reducing input voltage.
Power and tachometer value when this patent is a kind of ac motor rotation by detection control motor
Voltage swing reaches the method to motor speed control, and this method can make the revolving speed of motor reach the height of SRD motor
Revolving speed can be such that common AC motor is to maintain always at work in safe range again, will not in persistently high revolving speed power
It is excessively high and damage motor.
The setting of above-mentioned firm power range need to be determined in early period by a large amount of performance test, in general, electronic
The power of machine can be increased with the rising of revolving speed and resistance, can largely be sent out after the power rise a to stage of ac motor
Heat and damage, thus need for motor setting one firm power.Assuming that W is the firm power of motor, then motor
The power of motor can be detected and controlled when work automatically under firm power W, is not in that power is exceeded and damage electronic
Machine.
The above-mentioned firm power of motor generally refers to reach when motor operation maximum work when safety requirement temperature rise value
Rate, for example, the motor that product uses is F grades, then our temperature rise value is 120K, temperature rise reaches when such as test motor operating
Power when to 120k is 900W, then this 900W is exactly the firm power of this motor.
Multifunctional food processing unit in use, by operation panel select corresponding function gear, such as be crush or
Stirring, control unit receive motor gear rotary speed information, then start motor, speed measuring device and the power detection dress of motor
Set and power carried out to it always in entire work is made into, revolving speed detects and controls, motor is inputted to adjust with this
The size of voltage, so that it is excessively high and damage to be protected from motor power (output).
It should be understood that the above embodiments are merely illustrative of the technical solutions of the present invention, and rather than its limitations, part
Details can be realized in the form of other by corresponding design alteration.It will be understood by those skilled in the art that can be to above-mentioned implementation
Technical solution documented by example is modified or equivalent replacement of some of the technical features；And these are modified and replace
It changes, should all belong to the protection domain of appended claims of the present invention.
