Steppe Gearbox Nema 17 Customizable Stepper Motor 42BYGH 1.8 Degree 12 V 0.3 A
Since stepper motors and other control motors are designed to allow accurate positioning, the gearheads used for these motors must provide the same level of accuracy. Accordingly, Hetai Motor has developed a mechanism to minimize backlash in gears used with stepper motors in order to ensure low backlash properties.
Generally speaking, a stepper motor features greater output torque than an AC motor of the same frame size. Therefore, the stepper motor is designed to accommodate high torque and high speed so as not to diminish the motor's characteristics.
