Energization control system of a motor |
摘要 |
The energization control system for a motor equalizes the power loss of switching elements energizing coils of each phase of the motor in order to maintain a balance of heat development. The energization control system for a motor includes a plurality of phase coils and two switching elements. The energization control system of a motor supplies an electric current from the power source line to the coil when two switching elements are simultaneously conducted. Two switching elements are controlled under a first condition that one of the switching elements is switched every predetermined time while the other of the switching elements is conducted. Two switching elements are also controlled under a second condition that the other of the switching elements is switched every predetermined time while one of the switching elements is conducted. The first condition and the second conditions are repeated and synchronized to the predetermined time every predetermined period.
