Introduction Electrical motors are a big part of many industrial and commercial applications. However, like all mechanical devices, they are prone to failures. In this post, we will dive into the most common issues faced by two popular types of motors: induction motors and permanent magnet (PM) motors with inner and outer rotors. Understanding these…

The super short explanation for the difference between Permanent Magnet Synchronous Motors (PMSMs) and Asynchronous Induction motors (AC motors), is that PMSMs utilizes Permanent Magnets (PMs) in the rotor, to create the magnetic field, instead of a magnetizing current as AC motors. This reduces the power consumptions giving the PMSMs a generally higher efficiency and…
