Figure FDA0002524821600000031
t1＝288.15-6.5*R
wherein Q is1Representing the solved external environment pressure t of the driving motor (3)1Representing the solved external environment temperature of the driving motor (3), wherein R represents an air density value;
step A2, calculating the pressure and temperature inside the drive motor (3) according to the following formulas:
Figure FDA0002524821600000032
Figure FDA0002524821600000033
wherein Q is2Represents the solved internal pressure t of the driving motor (3)2Representing the solved internal temperature of the driving motor (3), k representing the adiabatic exponent of the gas, q representing the number of turns of the driving motor (3) per second, p representing the rated power of the driving motor (3), I representing the rated current of the driving motor (3), and gamma representing the humidity of the environment where the driving motor (3) is located;
step A3, calculating the adjusting coefficient of the driving motor (3) according to the following formula:
Figure FDA0002524821600000034
wherein η represents the adjustment coefficient obtained by solving, t2Representing the solved internal temperature of the driving motor (3);
step A4, judging whether the driving motor (3) needs to stop working according to the following formula:
Figure FDA0002524821600000035
wherein Qc represents the measured pressure inside the driving motor (3), tc represents the measured temperature inside the driving motor (3), and the driving motor (3) is required to start a protection device when G is 1, and the driving motor (3) is not required to start the protection device when G is 0.
