Zusammenfassung:The invention provides a permanent magnet type rotation motor and a washing machine using the same. The permanent magnet type rotation motor is free from effects of noise caused by a frequency converter and is capable of stably driving. The permanent magnet type rotation motor is provided with a stator. The stator is formed in a way that a stator iron core is formed by multiple teeth and an iron core back; insulation end plates are arranged on axial two end parts of the stator iron core; an armature winding which is wound in a concentrated manner is implemented in a way that the insulation end plates surround the teeth; the inner circumferential diameter of the stator rotates to freely support a rotor via a regulated gap; permanent magnets are stored in multiple permanent magnet inserting holes formed in rotor iron cores of the rotor; Hall sensor substrate housings for detecting positions of the permanent magnets are fixed on the insulation end plates; and sensor substrates installed on the Hall sensor substr
