Hi everybody.
I am going to start a project on the basic motion control of the Stepper motors. The problem is that I unluckily bought a motor with 4 wires and searching net i have found that its not that commonly used. I know it really IS USED but its interfacing has certain problem including the H-Bridge circuit.
Can anybody please help me starting work on this motor.
If i get to know the basic circuit I know I can proceed very quickly later on.
Final target is controlling the motor remotely.
Thanks.

 

That's a bi-polar motor, so requires two h-bridges to drive, far easier to get a uni-polar motor - old 5.25 inch floppy drives are a great source for these!.

hi
i need previous work for design traffic light controller.
now i work for design traffic light controller using fpga with verilog hdl.
thanks for all.

Hi,

They make controllers for 4 wire stepper motors, and these are quite
common.
You can either build a circuit yourself or buy one online.
There are parts made just for controlling and driving these motors.
You basically buy the parts, then do the board.

Will you be using a microcontroller or do you want to go with
standard off the shelf chips to build this?

 

You can get a driver for that 4-wire stepper at Sparkfun for $15 -- these are nice little boards; very easy to use.
