Motor control method and system and electronic equipment

The invention relates to a motor control method and system and electronic equipment. The method comprises the following steps: collecting the current variation of the motor and the temperature of a switching device of the intelligent power module in the process of controlling the operation of the motor by using the intelligent power module; under the condition that the temperature of the switching device is smaller than a preset first temperature threshold value, the switching frequency of the switching device of the intelligent power module is adjusted through the current variable quantity of the motor; and under the condition that the temperature of the switching device is greater than or equal to a preset first temperature threshold value, controlling the motor by utilizing an adjusting method corresponding to a temperature interval where the temperature of the switching device is located. According to the method and the device, the technical problem of triggering over-temperature protection due to too fas
