    This bidirecitonal rotation type adjustable speed AC motor features that its stator and rotor are similar to those of single-speed sync. or async. motor, but can rotate round same axis. Another adjustable speed motor (bidirectional rotation type adjustable speed motor or servo motor) or step (or stepless) mechanical speed regulator is used to regulate the space rotation speed of magnetic field in gap of motor, thus realizing step or stepless regulation of output rotation speed of motor with wide regulation range.
