FIELD: electrical engineering.
SUBSTANCE: proposed face-type electrical machine has single-disk stator and single-disk rotor, as well as reliable built-in braking device affording motor stopping as soon as field winding is deenergized. Rotor disk is coupled with rotor shaft through splined joint admitting axial displacement of rotor disk relative to shaft. Braking device disposed on one of bearing end-shields of machine frame is equipped with adjusting members enabling desired positioning of rotor disk inside annular space of machine and adjustment of brake spring pressure. Shaped supports are used for installing stator core separated from rotor core by air gap which are rigidly coupled with stator core and are free to displace relative to bearing end-shield whereon they are all secured upon setting desired air gap.
EFFECT: reduced size, facilitated maintenance, enhanced operating reliability.
