    Stepper Gearmotors

    A stepper motor and gearbox in one, choose these motors when you want high torque but don’t have space for a large motor. Their planetary gearbox efficiently transmits power to increase torque while reducing speed. These motors are great for motion similar to a 3D printer head, using precise, repetitive movements. Like the hands of a clock, their shaft turns in small, equal increments. When the shaft stops, it holds its position, even if there’s a counteracting force on the load. You can control the position of the load without configuring encoders or sensors. All are bipolar hybrid stepper motors, which deliver greater torque, precision, and efficiency than other types of stepper motors.
    Holding torque is the force needed to move the shaft out of position when it’s stationary. When the shaft is in motion, torque generally decreases as speed increases. Use a torque-speed curve to confirm which motor will work for your application. Click on a part number and select “Product Detail” to view the curve for a motor.
    All motors require a controller and driver (not included).
    Full Step Increment—Full step increment is the rotation of the shaft from one position to the next. The smaller the increment, the smoother and more precise the motion.
