A NEMA 17 stepper motor is a type of stepper motor that adheres to the National Electrical Manufacturers Association (NEMA) standard size 17, which specifies a mounting face of 1.7 inches (43.2 mm) square. Stepper motors are widely used in various applications, including robotics, 3D printing, CNC machines, and automation.
The NEMA 17 stepper motor is popular due to its compact size, high torque output, and accuracy. It typically has a step angle of 1.8 degrees per step, which means that it takes 200 steps to complete a full rotation of 360 degrees. However, some NEMA 17 stepper motors have a step angle of 0.9 degrees per step, which allows for even finer control and higher precision.
NEMA 17 stepper motors can be driven by a stepper motor driver, which converts digital signals from a microcontroller or a computer into the appropriate electrical signals to control the motor. They are available in different configurations, including bipolar or unipolar, and with different winding options, which affect their performance and power consumption.
42 stepper motor is a common stepper motor, which is widely used in various application fields, including but not limited to the following aspects:
1. 3D printer: 42 stepper motors are usually used to control the XYZ axis of the 3D printer and the feeding mechanism of the extruder to achieve high-precision printing.
2. Robot: 42 stepper motors are usually used in the joints and motion platforms of robots to achieve high-precision control.
3. CNC machine tools: 42 stepper motors are usually used to control various axes of CNC machine tools, such as XYZ axes and rotary axes, to achieve high-precision machining.
4. Automation equipment: 42 stepper motors are usually used for various position control and motion control in automation equipment, such as conveyors, packaging machines, printing machines, etc.
5. Textile machinery: 42 stepper motors are usually used to control various axes of textile machinery to achieve high-precision textile operations, such as looms, winding machines, hosiery machines, etc.
6. Medical equipment: 42 stepper motors are usually used for various position control and motion control in medical equipment, such as medical robots, medical imaging equipment, etc.
7. Automotive industry: 42 stepper motors are usually used for various position control and motion control in the automotive industry, such as door locks, sunroof controls, window lifters, etc.
In conclusion, the 42 stepper motor plays an important role in various automation and control applications, and its high precision, high reliability and high response speed make it the first choice for many industrial and commercial fields.
Because they are a good motor to move an object to a repeatable position, they are often used in robotics and in printers. Stepper motors come in a variety of sizes. The most popular sizes used in 3D printers are the NEMA 14, NEMA 17, NEMA 23, and NEMA 24.
NEMA 17 steppers typically have more torque than smaller variants, such as NEMA 14 and have a recommended driving voltage of 12-24V.
When it comes to choosing the best NEMA 17 stepper motor for a 3D printer, there are a lot of options available on the market. However, some of the factors you may want to consider when making your selection include:
1. Holding torque: This is the amount of torque the motor can generate when it is stationary. The higher the holding torque, the better the motor will be at maintaining precision and accuracy during printing.
2. Step angle: This refers to the angle through which the motor rotates for each step. The most common step angle for NEMA 17 motors is 1.8 degrees, but motors with a step angle of 0.9 degrees are also available.
3. Voltage and current rating: These specifications will determine the amount of power the motor can handle, which in turn affects its speed and torque.
4. Quality and reliability: Look for motors from reputable manufacturers with a proven track record of producing high-quality and reliable products.
Ultimately, the best NEMA 17 stepper motor for your 3D printer will depend on your specific needs and the requirements of your printer. It's always a good idea to do your research and choose a motor from a reputable manufacturer with proven performance and reliability in the 3D printing community.
1. The stepper motor has the maximum torque when it stops rotating.
2. Since the accuracy of each step is between 3% and 5%, and the error of one step is not accumulated to the next step, there is better positional accuracy and repeatability of motion.
3. Excellent start and stop and reverse response.
4. The response of the stepper motor is only determined by the digital input pulse, so open loop control can be used, which makes the structure of the motor relatively simple and costly to control.
5. It is also possible to rotate synchronously at extremely low speeds by simply connecting the load directly to the motor's shaft.
6. Because the speed is proportional to the pulse frequency, so there is a relatively wide range of speed.
