MOTOR EXCITING DEVICE AND MOTOR EXCITING METHOD AND MOTOR CONTROL DEVICE AND MOTOR CONTROL METHOD |
摘要 |
A motor control device which can determine a magnetic pole position for a magnetic pole position detector included in a permanent magnet motor in which the reluctance torque proportion is larger than the magnet torque proportion is provided. In a permanent magnet synchronous motor having multi-phase windings of N axes (N>=2), the windings of optionally selected K axes (K@N) are DC excited using corresponding independent power supplies. |
