Parameters of NEMA17 Stepper Motor
This high-torque NEMA 17 stepper motor delivers 0.95 Nm (134 oz-in) of holding torque, making it ideal for demanding linear motion systems requiring precise positioning and power. Its 2-phase design and 2.5A current rating provide robust performance for a variety of applications. While standard NEMA 17 stepper motors lack built-in encoders, this inherent simplicity reduces complexity and cost compared to servo motors. The higher pole count contributes to its superior torque output, exceeding that of many similarly sized servo motors.
High Torque: 0.95 Nm (134 oz-in) holding torque ensures powerful and reliable operation in linear motion systems.
Cost-Effective: The absence of a built-in encoder simplifies the design and reduces the overall cost compared to servo motor solutions.
Simple Integration: The standard NEMA 17 mounting pattern allows for easy integration into existing systems.
Versatile Applications: Suitable for a wide range of applications including robotics, CNC machines, 3D printers, and other automation equipment.
While this stepper motor excels in providing high torque, it's important to note the inherent characteristics of open-loop stepper motors:
High-Speed Limitations: Like all open-loop stepper motors, performance can degrade at high speeds due to potential missed steps. Consider a closed-loop stepper motor or servo motor if your application demands high-speed performance.
No Position Feedback: The lack of an encoder means the system has no inherent knowledge of the motor's actual position. External encoders can be added for closed-loop control if required.
For applications requiring absolute positioning and enhanced high-speed performance, consider hybrid servo/stepper motor solutions. These advanced motors combine the benefits of both stepper and servo technologies, offering:
Integrated Encoder: Built-in mechanical absolute encoders provide precise position feedback without the need for batteries or external sensors.
Closed-Loop Control: Eliminates hunting and simplifies gain tuning, resulting in smoother and more accurate motion.
High Efficiency: Advanced designs minimize heat generation, improving reliability and longevity.
Built-in Controller Options: Simplified integration and reduced system complexity.
