Asynchronous Motor (ASM)

Here, instead of being generated by permanent magnets (PSM) or electrical excitation (EESM), the rotor’s magnetic field is induced by the stator. On this type of motor, the rotor takes the form of a metal cage. The asynchronous motor offers the advantage of a more compact design and superior cost efficiency.
