FAQ for Outrunner BLDC Motor
Q:What is a Outrunner Brushless Motor?
A:In this outrunner brushless motor, the rotor (the outer casing with permanent magnets) spins around the stationary stator (the inner core with windings).This configuration provides a higher torque output at lower rotational speeds, making it ideal for applications that require strong turning force without a gearbox, such as direct-drive drone propellers.
Q:Can outrunner brushless motor Be Customized?
A: Yes,outrunner brushless motor can be customized. TSL Motors, a top dc motor manufacturer, offers options to adjust torque, speed, and voltage. This ensures the motor meets the specific needs of your application.
Q:Should I Choose an Inrunner or an Outrunner Brushless Motor?
A:Choose an Inrunner Motor if: You require extremely high rotational speed and excellent heat dissipation, and your application does not demand high torque, or if you are willing to use it with a gearbox.
Choose an Outrunner Motor if: You need powerful torque for direct drive applications (such as propellers or wheels), require moderate speed, and prioritize a compact structure and quiet operation.
