E22 : E-Series BLDC Motor
Size: 2.2 inches or 5.6 cm
Peak Torque: to 200 oz-in or 141 Ncm
High-Performance. High Torque-to-Weight.
The E22 series offers reliable performance in a small package for your low voltage, lower torque range applications. This series utilizes integrated hall effects to provide consistent speed in either rotation in a small envelope. The E22 series supports application speeds up to 15,000 RPM while providing long reliable performance.
