Key Takeaways

- The torque developed by a machine is directly proportional to the magnetic loading and electric loading.
- Different types of machines can be compared based on output power, power density, torque density, power to weight ratio, and torque to weight ratio.
- The inner diameter of the stator and length of the core can be calculated using the power equation and the aspect ratio.
- The aspect ratio varies for different power applications and can be adjusted based on the requirements of the application.
