Hey Guys
This is my first post,and I am in need of some help.I am attempting to construct a syringe pump using a linear actuator similar to the following DIY:http://panic.berkeley.edu/~ghe/DIY_SyringePump/.
1.Do you guys know where I can find/purchase a motor that has range of 1-10RPMs.
2.I am attempting to use a steeper motor from an old scanner, will this fulfil the requirements?
3.To control the speed of the motor would a voltage regulator be effective?
I suggest using a motor controller or motor driver to control the speed and implementing limit switches at each end. If you set them up right (this involves using a couple of diodes), they will only disable the motor in one direction (the one that would break something) while still allowing it move in the opposite direction.
1.Usage of a stepper motor requires alot of circuitry but at the same time the stepper motor offers a great degree of precision which I require for my experiments.
What I would like to know if IYO if the above methods can be applicable in modulating my linear actuator.
I am attempting to construct a syringe pump using a linear actuator similar to the following [...]The main reasons I am attempting to make the linear actuator rater than buying one is cost and the ones I have seen are too fast for my needs.I need the arm to move at a rate of ~500um/sec.
Now here are my questions:1.Do you guys know where I can find/purchase a motor that has range of 1-10RPMs.2.I am attempting to use a steeper motor from an old scanner, will this fulfil the requirements?3.To control the speed of the motor would a voltage regulator be effective?
