ELECTRIC DRIVE WITH CYCLOID PLANETARY REDUCTION GEAR

摘要

FIELD: electrical engineering; electric motors. SUBSTANCE: electric drive has housing with cover, electric motor incorporating permeable rotor, reduction gear mounted on motor shaft and used to impart rotary motion through high-speed bearings of planetary cycloid reduction gear to output shaft; permeable rotor is made in the form of spring welded to form common torus structure; magnetic core of motor has annular slots over entire side periphery that follow annular outline of spring turns and functions as fixed wheel of planetary cycloid reduction gear; permanent magnet provided with annular slots following annular outline of spring turns functions as movable ring; effective magnetic flux is transferred from stator to output-shaft permanent magnet through direct contact of permeable engagement between stator and rotor. EFFECT: reduced electromagnetic loss of drive. 10 cl, 4 dwg
