The invention provides an external-rotor permanent-magnet rotating motor which suppresses cost and reduces loss caused by a magnet. The external-rotor permanent-magnet rotating motor comprises the components of a rotor which is composed of a rotor core and a permanent magnet that is equipped at the inner diameter side of the rotor core; and a stator which has a stator core that is equipped at theinner diameter side of the rotor by a separating clearance and a coil that is formed in multiple troughs of the stator core, wherein the position of the rotor core for equiping the permanent magnet has the clearance.
