Comparison of Synchronous Motor Types
This video provides an overview of synchronous motors and compares different types.
00:00:00 This video provides an overview of synchronous motors and compares the three different types: permanent magnet synchronous motors (PMSM), internally permanent magnet synchronous motors (IPMSM), and surface permanent magnet synchronous motors (SPMSM).
๐งฒ Permanent magnet synchronous motors have permanent magnets in the rotor, generating a constant magnetic field in synchrony with the rotating field of the stator.
๐บ๐ป The difference between IPMSM and SPMSM lies in the position of the magnets: embedded in the rotor for IPMSM and on the surface of the rotor for SPMSM.
๐ก Externally excited synchronous motors use coils in the rotor to generate a magnetic field based on the current flowing through the coils.
00:01:10 This video provides an overview of synchronous motors and compares different types. It discusses the disadvantages of externally excited motors, the advantages of self-excited motors, and the working principle of reluctance motors.
๐ Externally excited synchronous motors have slip rings for current transmission.
๐ก The strength of the magnetic field in SESM can be adjusted without the need for current.
๐ Reluctance motors have no magnets or coils in the rotor and align based on magnetic resistance.
