Here are some key characteristics and features of a NEMA 24 stepper motor:

Size:

The "24" in NEMA 24 indicates its size, which means it has a frame size of 2.4 inches (60 mm) square.This standardized sizing system helps ensure compatibility with mounting brackets and other hardware.

Stepping Angle:

Stepper motors move in discrete steps, and the stepping angle of a NEMA 24 motor is typically 1.8 degrees per step.This means it rotates 1.8 degrees with each step, making it suitable for applications requiring precise control and positioning.

Holding Torque:

NEMA 24 motors come in various models with different holding torque ratings.Holding torque is the amount of torque the motor can exert to maintain its position when stationary.The specific holding torque depends on the motor's design and specifications.

Voltage and Current:

The voltage and current requirements of a NEMA 24 motor can vary depending on the model and application.It's important to provide the motor with the correct voltage and current to ensure proper performance.

Wiring:

NEMA 24 stepper motors typically have four or six wires, which are used to control the motor. Proper wiring and connection to a stepper motor driver or controller are essential for its operation.

Mounting:

NEMA 24 motors have a standardized mounting pattern, which makes it easier to attach them to various equipment and machinery.The mounting holes are typically positioned at specific distances and locations on the motor's frame.

Applications:

NEMA 24 stepper motors are commonly used in applications that require precise control of rotational motion, such as in CNC (Computer Numerical Control) machines for cutting and milling, 3D printers for layer-by-layer printing, and robotic systems for accurate positioning.

Stepper Motor Driver:

To operate a NEMA 24 stepper motor, you'll need a stepper motor driver or controller.These devices provide the necessary electrical pulses to control the motor's rotation and direction.

Microstepping:

Some stepper motor drivers support microstepping, which allows for even finer control of the motor's position by subdividing each step into smaller increments.This can improve the motor's overall performance, especially in applications where smooth motion is essential.

The key differences between an external linear, non-captive, and captive motor is,

External	Non-captive	Captive
The external linear motor has the screw affixed to the rotor, so it rotates external to motor body, like a DC motor.	The non captive screw travels freely in and out of the motor body and does not rotate.	The captive has a short screw that is held mostly inside the motor body, coupled to a spline.
External linear motors are most akin to motorized rails where the nut is replaced by a driven carriage assembly. Non captive is generally the shortest overall length assembly, while the captive is the longest.

FAQ

• What is stepper motor and how it works?

  The stepper motor is an electromagnetic device that converts digital pulses into mechanical shaft rotation. Advantages of step motors are low cost, high reliability, high torque at low speeds and a simple, rugged construction that operates in almost any environment.

• What is difference between DC and stepper motor?

  Some DC motors also generate high torques at low speeds, but are more suited towards continuous uses, as their torque is constant over their speed range. The main difference is that, while stepper motors can push harder from rest, DC motors tend to have more sustained output.

• How are stepper motors controlled?

• Why is it called stepper motor?

  Stepper motors are so named because each pulse of electricity turns the motor one step. Stepper motors are controlled by a driver, which sends the pulses into the motor causing it to turn.

• What is step angle?

  Step angle is defined as the angle through which the stepper motor shaft rotates for each command pulse.

• What is stepper motor torque?

  If external force is applied to a stepping motor when it is stopped but energized, the attractive force generated between the rotor and stator works to maintain the stop position of the motor. This torque of withstanding the external force is called the holding torque.
