By Controlled Motor Type
PMSM
- Permanent Magnet Synchronous Motors, similar to BLDC motors, have sinusoidal back EMF and are used in high-precision, efficient industrial and automotive applications.
Outrunner Brushless Motors
- These motors have the rotor outside the stator and are often used in applications like drones and electric skateboards due to their high torque-to-weight ratio.
Inrunner Brushless Motors
- With the rotor inside the stator, these motors are used in applications requiring higher speeds and lower torque, such as RC cars and some power tools.
Coreless Brushless Motors
- No iron core in the rotor reduces weight and inertia, making it ideal for lightweight, high-speed, and robotic applications.
