Use of a sine wave drive system with a smooth current waveform reduces noise, and generates less noise and vibration than motors with a rectangular wave drive system.
使用平滑电流波形的正弦波驱动系统可降低噪音,与使用矩形波驱动系统的电机相比,其噪音和振动均较小。
Signal distortion due to polarity switching, overshooting during signal fluctuations and extreme ramp angles in rectangular wave transmission are the rule for many isolation amplifiers available on the market.

The operating system of the hollow motor portion 21 according to the present embodiment employs a rectangular wave drive system in which position information of the hollow drive shaft 25 as a rotor is detected by the rotary encoder 34 and the encoder sensor 36, and rotation control is performed by switching a current conducting phase every 60 degrees (every 60 degrees with respect to electric angle of 360 degrees).
而且,本实施方式的中空马达部21的动作方式中,由旋转编码器34以及编码器传感器36检测作为转子的中空驱动轴25的位置信息,采用每60度(相对于360度电角度而为每60度)转换电流的通电位相而进行旋转控制的矩形波驱动方式。
Because the sine wave power supply when the voltage is close to zero, will make the flash moment break, and the rectangular wave flash can evenly throughout the cycle.
因为正弦波电源当电压接近零位时,将使闪光瞬间中断,而矩形波可在全周期内均匀产生闪光。
It converts the magnetic field changes to current signals (rectangular wave) and transmits them to the ABS actuator and electric unit (control unit).
它将磁场的改变转换为电流信号 (方波),并发送到 ABS 执行器和电气单元 (控制单元)。
Adopt 16 embedded microprocessors, operation is fast, the precision high, the rectangular wave excitation of low frequency of the programmable frequency, having improved the stability that the flow measures, low power dissipation
采用定制的双层屏蔽电缆 7. 可编程频率低频矩形波励磁,提高了流量测量的稳定性,功率损耗低
Moreover, in FIG. 10, the amplitude of a servo signal significantly increases upon the first gain switching from low gain to high gain at step S705. This results in saturation of the servo signal, thus causing the servo signal to exhibit a rectangular wave whose waveform is not what is expected.
另外,在图10中,伺服信号的振幅在(S705)中第一增益从L增益切换为H增益的时刻显著变大,导致伺服信号饱和,伺服信号变为与期待的波形不同的矩形波。
