Applications
Q: What is the difference between an inrunner BLDC motor and an outrunner BLDC motor?
A: An inrunner BLDC motor has the rotor located inside the stator, meaning the inner shaft rotates while the outer shell remains stationary. These BLDC motors typically spin at higher RPMs with lower torque and are well-suited for applications requiring compact size and precise control, such as RC cars, drones with gear reduction, or high-speed fans.
In contrast, an outrunner BLDC motor has the rotor on the outside, which rotates around a stationary stator. This design allows for higher torque at lower RPMs, making them ideal for direct-drive applications like quadcopters, electric skateboards, or gimbals. The larger rotating mass in outrunners contributes to better torque output without requiring additional gearing.
