APPARATUS FOR CONTROLLING 3-PHASE MOTOR AND METHOD FOR MAINTAINING HIGH TORQUE THEREIN |
摘要 |
Provided are an apparatus for controlling a 3-phase motor and a method for maintaining a high torque therein, which are capable of preventing excessive heat generation in a coil, through which a phase current flows, by causing an AC current to flow in a specific phase when a 3-phase motor maintains a high torque. The apparatus for controlling the 3-phase motor includes: a sensor configured to sense torques flowing through three phases of the 3-phase motor; and a controller configured to determine whether the torques of the three phases, which are detected by the sensor, maintain a high torque, and to perform control such that, when it is determined that the detected torques maintain the high torque, a DC signal is applied to a specific phase among the three phases and an AC signal is applied to the other phases. |
