Why step motors are still popular |
Posted: March 10, 2019 |
Stepper motors are often misunderstood as less reliable than servo motors, but they are actually as reliable as servo motors. The stepper motor operates by accurately synchronizing with the output pulse signal from the controller to the stepper motor driver to achieve high-speed position and control. Stepper motors have high torque and low vibration at low speeds, ideal for applications requiring fast positioning in short distances. "Stepper motor? Servo motor must have better performance." This is a typical reaction when asking you to make cnc machines for stepper motors. Obviously there is a big misconception about step motors. In fact, step motors have been used in different types of applications such as advanced equipment and automated tools or solutions for drive systems that require high precision, such as automation. factory (FA), semiconductor manufacturing equipment, FPD and solar panels, medical devices, analyzers, financial systems, food packaging machines and aperture adjustment for cameras . Why should you use a step motor? Today # CNC3DS will give you comprehensive information about the advantages of step motors Easy to use: 34% Inexpensive: 17% Simple operation: 16% No adjustment: 12% Other: 21% * Number of respondents: 258 Key points: Easy to use, simple operation and low cost According to the survey of many brothers using stepper motors, the stepper motor: "easy to use", "simple operation" and "soft price" derive from the fact that when you do automation or cnc, buy one Stepper motor kit can save a decent item compared to servo. This means that many of you use step motors thanks to its simple, cheap and easy-to-control structure. However, some brothers may be skeptical about the engine's actual performance, in terms of its accuracy and torque. We will have some comparisons with servo motors through the following characteristics: For example, when using Oriental motor step PK566 and RKD514L-C to position the turntable, its stop accuracy is within ± 0.05 ° (without load). Due to failure to accumulate position error between steps, it is possible to locate high accuracy. The structure of the stepper motor does not require an encoder, allowing a simple and low-cost drive system.
