Linear actuators... Need some help

[kawasaki636]

Hello my name is Nick i just purchased some linear actuators with encoder motors for a good deal and was hoping to put together a 3 or 4 dof simulator. I have a basic understanding of how the encoders and motors work and communicate, it just seems like the more i read the more confused i get about what i actually need. I plan on using Arduino Uno board... what i'm not sure about is how to connect the motor (from what I've read the motors are 36-170vdc and need a 2 phase MOSFET h-bridge for PWM?), do i need more than just a power supply and an h-bridge board to control it? And which H-bridge board should I use?

Any help or info would be greatly appreciated.

thanks,

hello!

you should investigate sabertooth + kangaroo:
it can work with encoders (but max voltage is only 24VDC)

You might ask Telfel who managed to use encoders!

The "stepper" motors you got work with step and direction. One line that pulses (enables the motor) and another that indicated the direction.

Not sure if its possible to drive them directly with arduino as the pulse requirements are a little tight:
"200 nanosecond-pulse minimum"...
"40% - 60% duty cycle (2 MHz max pulse rate)"

You will probably need a stepper signal controller (usually a PCI card for PC). Not trying to burst your bubble but its just not easy with some industrial equipment that need "strict" standards...
