FIELD: electrical engineering;, permanent-magnet excited disk-rotor commutator motors.
SUBSTANCE: proposed electric motor has stator and disk rotor. Stator has frame in the form of barrel, permanent-magnet alignment unit, as well as brush yoke with brush holders and brushes. Permanent-magnet alignment unit is usually made in the form of disk. Each permanent magnet is disposed in alignment unit seat assembled of two magnetically permeable plates mounted one on top of other and rigidly fixed together. First plate facing the rotor has through notches, each accommodating permanent magnet secured on second plate. Size of each notch in first plate corresponds to that of permanent magnet disposed therein. Brush yoke is made of insulating material and preferably mounted on second plate of alignment unit.
EFFECT: simplified mechanical design.
