VEX V5 Smart Motor - VEX 276-5842, Mechanisms such as flywheels and arms do not need large external gear ratios if the output shaft speed of the driving motor is already close to the desired speed or torque. Therefore, changing internal gear ratios to fit specific needs allows more efficient and compact mechanisms to be designed. This cartridge has a 6:1 ratio, giving a maximum output speed of 600 rpm. Great for low torque, high speed applications such as intake rollers, flywheels, or other fast moving mechanisms. VEX V5 Motor 6:1 Cartridge Blue (600 RPM)
