Re: Controlling Solenoid Speed

The analogy may lead to an incorrect conclusion.

A Spike receives a small electric signal and switches a large electric current by opening and closing electrical contacts.

A Solenoid receives power on/off and switches pneumatic flow on/off by sliding a mechanical valve open/closed.

They are somewhat analogous but not necessarily "just like" Spikes concerning the effects of switching.

In a given application, it may be possible to find a switching frequency for the solenoid which avoids problematic resonances and stresses and yet provides the desired flow regulation.

I'd be curious to know if there are any teams who have had success doing this.
