NS35

The non-switching driver NS35 is ideal for disk inspection equipment where noise is averse when combined with an air spindle.

Noiseless control
The control section is made up of only hardware logic circuits and analog circuits, rather than a conventional microcontroller that uses a high-speed clock, resulting in less noise.
Non-switching drive
The power element that drives the motor is not an ON/OFF switching operation, but a non-switching (linear) operation, so it generates less noise.
High rotational accuracy speed
Highly accurate rotational speed can be obtained by combining sine wave drive, which reduces torque ripple, and PLL control using encoder signals.
