Hi, For some of our experiments, we are looking for a programmable motor to simulate respiratory motion and move a cylindrical foam. We expect the motor to be able to simulate simple sinusoidal motion (different frequencies and amplitudes). We also need the motor to be able to get other motion patterns (similar to but not sinusoidal) as input and move accordingly. I was wondering if anyone could help me with recommendation on product lines that match our need.
Hi,
Can you provide further information about your application ? Can you describe the motion of the foam ? Do you want to rotate the cylindrical foam or move it up and down ? Do you have an example, video, diagram for the system you are trying to build ?
Regards,
Thanks for your response. We are looking for a motor that can generate a linear motion with an amplitude of about 6 cm. The motion needs to be reproducible within ±1 mm. With respect to the speed, we are looking for periodic motions with periods of 0.5-10 sec. This parameter should be independent from the motion amplitude, meaning that we should be able to set each of them separately. Regarding the weight we want to move, we are talking about moving a weight of about 2-3 kg (including the friction) horizontally.
As I mentioned earlier, we need to produce periodic motions, both sinusoidal and irregular. So, the motor needs to be programmable using an interface or so.
I hope these info are adequate. Please let me know if you need more info.
You can probably use a linear actuator with an appropriate DC Motor controller for this application.
For example, this L16 Linear Actuator, 100mm, 150:1, 12V w/ Potentiometer Feedback might interest you. You can control it with the Actuonix Linear Actuator Control Board interfaced with a microcontroller like an Arduino UNO Board.
