Linear actuator movement via frequecy

Help & Support Robot Parts

Hi

I would like to vary the length of a linear actuator via frequency, is this possible?

What I mean is if I have an 8" actuator I would like to have it at its lowest setting at 30hz but when I introduce a 27.5hz frequency I would like it at mid point and at 25hz I would like to have the 8" actuator at full.

I thought you guys might be able to help me out with this in terms of advice please, I am a total novice to actuators and such like.

Thanks.

Thanks for the advice.

Do you know where I could get such a controller or someone who could make one?

Hello,

Does it exist control boxes that we can connect to the linear actuator to control the speed of the motor?

Thank you :smiley:

Never heard of this before. DC linear actuators are operated the same way as brushed DC motors. The actuator simply needs a voltage, and switching that voltage switches the direction of motion. The motor controller takes care of varying the speed (for example using PWM). You’d need some sort of motor controller which can be operated based on frequency, or better yet - have a microcontroller measure the frequency, and then send the appropriate commands to a motor controller to move the actuator.

Yes - that’s a “motor controller”.

Unfortunately we do not have a list of consultants / designers.
