Abstract
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.
