Product description
Referencing the image to your right, the power section cross-section (or profile) shows different "lobed" rotors inside their corresponding stator. The power section profiles are designed with these different ratios to allow for specific motor speeds and torques. Motor speed can be easily changed just by changing the rotor/stator lobe ratio. Generally, the higher the number of rotor/stator lobes yields a power section with a slower speed and higher torque. Fewer rotor/stator lobes yields a power section with a higher speed and lower torque.
