Abstract: A method of controlling a rotational speed of a motor of an electric bed includes the following steps. (A) Use a sensor to detect rotation of the motor, set a predetermined rotational speed of the motor in a microcontroller, and use the microcontroller to calculate actual rotational speeds of the motor. (B) Use the microcontroller to calculate an average actual rotational speed of the motor at each of sampling time points in a predetermined period. (C) Use the microcontroller to compare the average actual rotational speed of the motor with the predetermined rotational speed to obtain a difference signal. (D) Input the difference signal to a driver circuit to adjust the rotational speed of the motor until the average actual rotational speed of the motor is equal to the predetermined rotational speed. In this way, the motor of the electric bed can approximately rotate in the predetermined rotational speed.
