It is dynamic.
When the first torsion and/or the second torsion are less than torsion predetermined threshold value, and current value is less than preset stopping threshold value, example
When such as preset stopping threshold value being 0.5A, it may be determined that stirring kind equipment work is completed, and can stop motor rotation at this time.It is preferred that
Ground, when judging current value, considers whether electric current reaches preset time threshold less than the time of preset stopping threshold value, to avoid electricity
Flow valuve is less than the state that preset stopping threshold value is moment, and stopping the rotation of motor causes stirring kind equipment not work normally.
Preset time threshold is referred to user and launches the time of food materials and the safety time setting of stirring kind equipment zero load, for example, if
It is too short to set detection time, when user's release time is slower, can cause to protect by mistake.So the time of setting is greater than user's
The average release time, but if time setting it is long, the situation of damage screw rod occurs in feed screw idle running for a long time, empty
Time most long no more than 1 point of 30S is carried, so preset time threshold can select between 30S to 1 points of 30S.
Further, which further includes：
Rotation speed detection unit, is connected with motor, for detecting the rotating speed of the motor, and feeds back to master chip；
The master chip, is connected with the rotation speed detection unit, is additionally operable to according to overload and working status generation
After first rotation direction switching command, the operating status of motor is determined according to the rotating speed of the motor, and according to operating status
Produce the second rotation direction switching command；The motor-drive circuit, is additionally operable to according to the second rotation direction switching command,
The motor is driven to be rotated according to the second direction indication.
Due to feed screw become seized or jammed, motor needs to carry out reversion unloading, for example, motor needs instead in unloading
Turn 2-3 circles, if motor speed is 50-60RPM, then the motor reversal unloading required time is 2-3S.Thus, pass through inspection
The rotating speed of measured motor can determine that the operating status of motor, such as motor need to invert the time of operation, when reversion run time
Afterwards, motor needs to continue to rotate forward squeezing food materials.Wherein, the second rotation direction switching command can be that motor is cut by inverting
It is changed to rotating forward.
The master chip, is specifically additionally operable to：
According to the rotating speed of motor, the corresponding preset time of motor operation predetermined amount is determined；In motor according to the first instruction
After direction rotates the preset time, the second rotation direction switching command is produced.
The present embodiment detects the current value of motor by increasing current detection circuit, and the mistake of motor is determined by the current value
Load state, ensures motor operation safety, and produces first according to the overload of motor and the working status of agitating element and rotate
Direction switching command, realizes the automatic switchover of direction of motor rotation, avoids manual switching, realizes making terseness and relaxing for equipment
Adaptive.
