METHOD FOR CONTROLLING MOTOR OF AIR CONDITIONER |
摘要 |
The present invention relates to a method of controlling a three-phase motor of an air conditioner by using an inverter including a total of three pairs of upper and lower arm switching elements connected in parallel, wherein the motor includes a stator coil and a rotor of a permanent magnet and the upper and lower arm switching elements are connected in series to form a pair, the method including the steps of performing field weakening control in order to improve a velocity of the rotor by offsetting an amount of magnetic flux, generated by the permanent magnet, in a state where a PWM signal having a maximum duty is applied to the motor, and controlling a zero vector application time applied to the upper arm switching elements or the lower arm switching elements to become a specific value or more. Accordingly, a minimum zero vector application time can be secured. |
