The NEMA 17 stepper motors are unique in their features with a hybrid stepper motor consisting of the 1.7×1.7-inch faceplate. For smooth rotation, they have a 0.9/1.8 degree per step and good holding torque. This is commonly used in the deployment of robotic arms, 3D printers and many other applications. One can pick the required supply voltage and motor based on the need of the application. They have a sleek design and are compact. They show excellent performance in terms of speed, torque, and step resolution. Further, the interference factors like the value of the current, magnitude of the voltage, temperature change, and the waveform do not affect the step value of the NEMA 17 stepper motor.
They come with a lot of benefits compared to any other motors out in the market. They undoubtedly outperform any other type of motor due to its unique features. Conversely, there are also a few weak points where it might not be that effective. However, the main advantage is its ability to enable outstanding position and speed control of the motors. The feature has proven fruitful results when used in different applications like dosing, production, and industrial equipment.
The positional accuracy
Generally, the common use of a stepper motor while using it in motor-controlled appliances where we require high positional accuracy. It comes into play when the conventional DC motor fails by turning constantly, where it can turn an exact number of given steps. In one revolution a it can generally turn to 25600 steps. The number of degrees per each step in the stepper motor can enable the motor to move from a particular fixed position to another position given at any point in the circle. In standard 200 step motors, they can turn up to 1.8 degrees per step. By using highly sophisticated series drivers, the movement can be controlled accurately with programmable deceleration and acceleration curves being applied. This method is mainly useful in process control and dosing applications where one needs to attain exceptional accuracy.
The performance of a stepper motor is heavily affected by the build quality of the motor in use. The conventional aspects like the quality of the magnets and bearings are of great importance. However, the controller plays a key role in determining the potential of the stepper motor. It can convert the digital input voltage and current into motor speed and torque. Hence, the key aspect lies in their ability to start and stop at any required point with remarkable accuracy. By combining the stepper motor with a simple, intelligent motor controller, we can attain high performance and positional accuracy that is beyond the scope of any other motor. These remarkable features find their way into many applications.
