NeveRest 40 Gear Motor with 40:1 reduction and encoder

NeveRest 40 Gear Motor with 40:1 reduction and encoder: rise to the challenge

NeveRest motors are some of the most commonly used in the FIRST Tech Challenge Game, because their geometry conforms to the competition’s rules with a 6 mm diameter output shaft (and a 37 mm diameter gearbox housing). Its steel and plastic design makes it a high-strength motor.
