External Rotor PMSM Technology for Energy Generation and Durability

The global drive towards increased energy efficiency and sustainability has led to the widespread adoption of external rotor permanent magnet synchronous motors (PMSMs) across various industries. These motors have emerged as a preferred technology, thanks to their high efficiency, low maintenance requirements, and compact size. The design of external rotor PMSMs allows them to achieve higher power density, making them ideal for applications that require high power output such as robotics, machine tools, and electric vehicles. They are an excellent choice for wind turbine applications where their high efficiency and low cogging torque are required for generating electricity.

In this webinar, we will focus on the design of an external rotor PMSM and delve into its electromagnetic behavior using EMWorks2D software solution. We will also analyze cogging torque generation by studying the impact of magnet pole arc variation on the machine's operation to ensure optimal performance and reliability.
