Hybrid Stepping Motor At Several Different Points

First, the control accuracy of different

       Two-phase hybrid stepping motor step angle is generally 3.6. , 1.8. , Five-phase Hybrid Stepping Motor step angle is usually 072. , 036. . There are also some high-performance Hybrid Stepping Motor step angle is smaller. Stone produced as a tool for walking wire Hybrid Stepping Motor, the step angle of 0.09. ; Germany one hundred Benguela (BERGER LAHR) production of its three-phase hybrid stepping motor step angle can be set via DIP switch 18. , 09. , 072. , 036. , 018. , 009. , 0072. , 0036. (By a stepping motor drive segment), compatible with a two-phase and five-phase hybrid stepping motor step angle.

      AC servo motor control accuracy by the motor shaft rotary encoder back guarantee. To ** all-digital AC servo motor, for example, for the standard 2500 with a line encoder, motor, since the internal drive uses a four-frequency technology, the pulse equivalent to 3600110000-0. 0360. For the 17 bit encoder with the motor, the driver receives 217-131072 pulses per motor revolution, that is, its pulse equivalent to 3600 / 131072-9 89 seconds. Is the step angle of l 8. Hybrid Stepping Motor pulse equivalent of 1 / 655.

Second, the low-frequency characteristics of different

       Hybrid Stepping Motor at low speeds prone to low frequency vibration. Vibration frequency and load conditions and performance of the drive is generally believed that the vibration frequency of the motor no-load take-off frequency is half the battle. This works by the Hybrid Stepping Motor vibration frequency determined for the normal operation of the machine are very detrimental. When the Hybrid Stepping Motor at low pressure using the general low-frequency vibration damping technology to overcome the phenomenon, such as the increase in motor damper, or drive on the use of segmentation techniques.

      AC servo motor is running very smoothly, even at low speed vibration will not occur. AC servo system has a resonance suppression, can cover the lack of mechanical rigidity, and a frequency resolution function within the system (FFTl, can detect mechanical resonance point, easy system tuning.
