Permanent magnet and variable frequency integrated machine

Abstract

A permanent magnet and variable frequency integrated machine includes a variable-frequency drive (VFD) and a permanent magnet motor, where the permanent magnet motor extends forwards and backwards in an axial direction thereof, the VFD is integrated on a peripheral side of the permanent magnet motor, and a power supply and distribution apparatus, detachably connected to the VFD, is further provided on the peripheral side of the permanent magnet motor, and configured to provide electric energy for an electric device. The permanent magnet and variable frequency integrated machine adopts the design concept of integrating a VFD, a power supply and distribution apparatus and a permanent magnet motor, which can satisfy the application requirement for a small volume. In addition, modular designs of the VFD and the power supply and distribution apparatus are implemented, thereby facilitating on-site replacement and maintenance.
