The present invention discloses a motor deceleration method which is applied to a motor driving apparatus. The motor driving apparatus includes an energy-storing unit and a controlling unit, and outputs a driving signal to control the motor. The controlling unit controls a driving frequency of the driving signal. The driving deceleration method includes following steps of controlling the driving frequency to zero; increasing the driving frequency in a linear way by using the controlling unit; detecting whether a terminal voltage difference of the energy-storing unit is increased to a preset voltage value, and if yes, adjusting the driving signal to keep the terminal voltage difference at the preset voltage value; and reducing the driving frequency continuously to decelerate the motor. |
