In the case of motor abnormality (i.e. motor breaks down for example, motor shaft cannot be rotated by foreign matter winding), in self- recoverage element
The temperature in portion rises rapidly, and high molecular polymer expands rapidly, so that the impedance increase of self- recoverage element, as a result, with the
The electric current in the circuit of one element series connection becomes smaller, so that the circuit where first element is off, obtains protection electricity
The purpose of machine.And after motor abnormality exclusion, since the temperature of self- recoverage element is not enough to maintain its high-impedance state, from
The impedance of resetter is restored to original state, so that the circuit where first element is in the conduction state, motor can
Normal operation.
In addition it is also necessary to explanation, above-mentioned second element be electrical-coil, the operating parameter of second element can be but
It is not limited to the temperature of electrical-coil and flows through the electric current of electrical-coil.
Specifically, the sensor in the system of control motor can collect the resistance value and the of first element in real time
The parameters such as the temperature of two element, the electric current for flowing through second element, wherein, acquire sensor, the acquisition the of the resistance value of first element
The sensor that the sensor of the temperature of two element and acquisition flow through the electric current of second element can be same sensor, also may be used
Think multiple sensors.
Step S104 adjusts the resistance value of first element according to the operating parameter of second element.
It should be noted that when motor causes motor to be unable to operate normally by foreign matter winding, the electricity of electrical-coil is flowed through
Stream will sharply increase, and the temperature of electrical-coil can also increase, therefore, can be according to the increase for the electric current or electric current for flowing through electrical-coil
The incrementss of the temperature of amount and the temperature or electrical-coil of electrical-coil adjust the resistance value of first element, the resistance of first element
Value increases to preset resistive value, and then the circuit where making first element is off, and motor is protected so as to reach
