The Review of: 42 Series Motor through screw NEMA17 stepper motor linear screw 200MM telescopic reciprocating piston 42HA48-T8*8 for 3D printer Review

The NEMA 17 stepper motor is a popular choice for various applications, including 3D printers. Let’s break down the components mentioned in your query:

  1. NEMA 17 Stepper Motor:

    • The NEMA 17 refers to the motor’s standard size, which is 42 x 42 mm.
    • It operates with a 1.8-degree step angle and has 4 phases.
    • The motor length is approximately 1.54 inches.
    • It has 200 steps per revolution, resulting in a step size of 1.8 degrees.
    • The rated voltage is 12V DC, and it draws a current of 1.2A at 4V.
    • The unipolar holding torque is 22.2 oz-in.
    • This motor is commonly used in applications that require precise control and positioning.
  2. Linear Screw (Lead Screw) Actuator:

    • The 200mm telescopic reciprocating piston you mentioned likely refers to a linear actuator.
    • It combines a NEMA 17 stepper motor with a lead screw (screw rod).
    • The lead screw converts rotary motion from the motor into linear motion.
    • The 200mm stroke indicates the maximum distance the actuator can move.
    • Linear actuators are used for tasks like moving printer beds, adjusting focus, or opening/closing doors.
  3. 42HA48-T8*8:

    • The specific model number 42HA48-T8*8 might refer to the lead screw specifications.
    • Unfortunately, I couldn’t find detailed information about this exact model.
    • However, it likely corresponds to the lead screw’s pitch (T8*8), which determines how much linear motion occurs per revolution.

In summary, the NEMA 17 stepper motor with a 200mm lead screw is a versatile choice for 3D printers and other applications requiring precise linear movement. It combines the benefits of stepper motors with the functionality of a lead screw to achieve accurate positioning and control.
