Hybrid Stepper Motor Very Smooth

Nair Motion Technologies Co.,Ltd | Updated: Oct 30, 2017

Stepper motor is a discrete motion device, it and modern digital control technology has an essential link. In the current domestic digital control system, the application of stepper motor is very extensive. Hybrid Stepper Motor With the advent of all-digital AC servo systems, AC servo motors are also increasingly being used in digital control systems. In order to meet the development trend of digital control,Hybrid Stepper Motor most of the motion control system using stepper motor or all-digital AC servo motor as the implementation of the motor. Although both are similar in control mode (burst and direction signals), there are significant differences in performance and application. Now compare the performance of the two.

Stepper motor at low speed prone to low frequency vibration phenomenon. The vibration frequency is related to the load condition and the drive performance. Hybrid Stepper Motor It is generally believed that the vibration frequency is half of the motor no-load take-off frequency. This low-frequency vibration phenomenon, which is determined by the working principle of the stepper motor, Hybrid Stepper Motor is very unfavorable to the normal operation of the machine. When the stepper motor is operating at low speed, damping technology should generally be used to overcome the low frequency vibration phenomenon, such as in the motor plus damper, Hybrid Stepper Motor or drive on the use of sub-technology.

AC servo motor running very smoothly, even at low speed will not appear when the vibration phenomenon. AC servo system with resonance suppression function, can cover the lack of mechanical rigidity, and the system has a frequency resolution function (FFT), can detect the mechanical resonance point, Hybrid Stepper Motor easy to adjust the system.

The output torque of the stepper motor decreases as the speed increases and decreases drastically at higher speeds, so the maximum operating speed is typically between 300 and 600 RPM. AC servo motor for constant torque output, that is, its rated speed (usually 2000RPM or 3000RPM) within, can output the rated torque, above the rated speed for the constant power output.

Stepper motors generally do not have overload capacity. Hybrid Stepper Motor AC servo motor has a strong overload capacity. To Panasonic AC servo system, Hybrid Stepper Motor for example, it has a speed overload and torque overload capacity. The maximum torque is three times the rated torque and can be used to overcome the moment of inertia of the inertia load at the moment of activation. Hybrid Stepper Motor Stepping motor because there is no such overload capacity, in order to overcome this inertia moment in the selection, Hybrid Stepper Motor often need to select a larger torque of the motor, and the machine during normal work without the need for such a large torque, there is a moment The phenomenon of waste.
