Tiivistelmä
This thesis focuses on the electromagnetic performance analysis of surface mount permanent magnet synchronous motors. With the development of the electrification trend, permanent magnet motors are a key technology in electric vehicles, household appliances, industrial automation, and other fields, people have higher and higher requirements for their performance and efficiency. Surface mount technology, as an advanced manufacturing process, provides new possibilities for motor design and manufacturing.
Permanent magnet motors are divided into permanent magnet DC motors and permanent magnet AC motors. A permanent magnet AC motor refers to a polyphase synchronous motor with a permanent magnet rotor, a permanent magnet synchronous motor (PMSM). This study will conduct an in-depth analysis based on the electromagnetic performance of the permanent magnet synchronous motor to fully understand its complexity and explore its potential impact on various applications.
Preliminary research has achieved important results, including an in-depth understanding of the structure, working principle, mathematical equations, and performance calculation methods of permanent magnet synchronous motors, as well as the differences and advantages of surface-mounted and built-in permanent magnet motors. This study will use finite element analysis software (ANSYS) to analyze the electromagnetic field of the example. The design process for a surface-mounted permanent magnet synchronous motor will be based on an understanding of the compressor application, deriving dimensional equations, determining the number of slots and poles, and specifying its major dimensions. Finally, we will optimize the main dimensions and parameters again, calculate the electromagnetic field, and evaluate the motor performance to achieve high torque density and efficiency.
Based on the above theory, this article will design and analyze a 2kw permanent magnet synchronous motor. We will complete basic experimental testing by determining the basic structural parameters of the motor and utilizing computer-aided electromagnetic design and finite element simulation.
