摘要： A driving control device of a motor includes a temperature sensing circuit, a comparing circuit, a rotation speed control circuit and a driving circuit. The temperature sensing circuit detects an environmental temperature for generating a sensing signal. The comparing circuit is electrically connected to the temperature sensing circuit, and compares the sensing signal with a reference voltage signal for outputting a comparing signal. The rotation speed control circuit is electrically connected to the comparing circuit and has a first threshold voltage and a second threshold voltage, both of which are compared with the comparing signal for outputting a rotation speed control signal. The driving circuit is electrically connected to the rotation speed control circuit, and generates a driving signal to drive the motor in accordance with the rotation speed control signal.
