Brushless motors with neodymium magnets represent the very latest form of electric power plant. Outrunners in particular require no reduction gearbox, and constitute efficient, high-torque motors covering a broad range of power levels.
The special construction of outrunner motors often enables them to drive large propellers without the need for a gearbox, so they are ideal for direct-drive applications.
ROXXY BL outrunner motors of the D and CA series are equipped with triple ballraces. To improve precision and smooth-running, a third ballrace, known as a thin-section bearing, is fitted. This prevents the motor bell distorting under load, ensuring smooth running.
