Motor Design Engineering Considerations - III — Lesson 3

This lesson covers the fundamentals of motor design and adaptation. It delves into the various aspects of motor design, including the controller, electronics, software, electromagnetic stock production, and thermal considerations. The lesson also explains how to make small changes to a motor to improve its performance, such as increasing its speed or efficiency. It further discusses the impact of changing the number of turns in the winding and the effect of increasing the length of the motor. The lesson concludes with a discussion on emerging trends in motor design, including the use of rare earth magnets and axial flux motors.

Key Takeaways

- Small changes to a motor, such as increasing the number of turns in the winding or the length of the motor, can significantly impact its performance.
- Increasing the number of turns in the winding can lead to a more efficient motor or a motor that can deliver much more torque.
- Increasing the length of the motor can lead to a higher torque motor with lower speed.
- Emerging trends in motor design, such as the use of rare earth magnets and axial flux motors, offer new possibilities for improving motor performance.
