Momotaro series


Momotaro series

Because the waveform is tuned to our motor, and the sine wave power supply is realized, the noise sound is reduced and the quiet drive is possible compared with other square wave power supply. If the requested quantity is large, we will be able to provide you with a board unit, and we will also consult you for custom changes such as board shape with inexpensive budget. For specific conditions, please consult with our sales representatives.
