Most common single-phase AC motors use the squirrel-cage rotor which will be found in virtually all domestic and light industrial alternating current motors. The motor takes its name from the shape of its rotor "windings"- a ring at either end of the rotor with bars connecting the rings running the rotor

Precise control of the permanent magnet bond line thickness–the distance between the magnet and substrate–is critical for minimizing the rotor-stator air gap. Minimizing the air gap distance has a direct relationship to the motor s energy efficiency. 3M™ Magnet Bonding Adhesive AU-205 contains a built-in thickness system providing electric

Permanent-magnet (PM) motors have a stator winding configuration similar to the three-phase induction motors but they use permanent magnets in the rotor instead of a squirrel cage or wound rotor. The permanent-magnet rotor tracks with synchronism the stator rotating field and therefore the rotor speed is equal to the rotating magnetic field

AC Induction/Asynchronous The majority of industrial motors are three-phase AC induction motors due to its reliability and low cost. In this case the electric current in the stator winding generates a rotating magnetic field that "induces" (hence the name) electric current in the rotor. The current induced in the rotor create a magnetic field that reacts against the stator
AC induction designs use steel laminations in both the stator and rotor these can be stamped almost simultaneously from the same sheet of material. In other words the scrap rate is much lower than your average stamping job. However the unique
Stator is one of the key components of BL motor. In connection with controller it generates a changing magnetic field in the motor and in interaction with rotor enables its rotation and torque transmission to the shaft.

A Permanent Magnet Synchronous Motor is composed of a stator and a rotor. The stator is the same as an asynchronous motor consisting of a three-phase winding and a stator core. A pre-magnetized permanent magnet is installed on the rotor and a magnetic field can be established in the surrounding space without additional energy which simplifies the motor structure and saves energy.
