    Stepper motor circuit problem

    motor na 5v Rambo i am already running with that circuit u suggested as i knew 7805 could take only 1A. Added after 6 minutes: VVV i havn't understood. What do u mean " power up one phase at a time". How to do it?????????

    Stepper motor circuit problem

    6 phase motor circuit I already am running the 7805 with large sized heat sink but still this problem is there. Which other regulator can i use by the way. Can u suggest plzzzzz.......... Thanks very much, u have been of tremendous help.......

    Stepper motor circuit problem

    unipolar stepper motor circuit I am still not very clear where should i measure if the motor is getting 2A current or not ? Secondly i am using a heavy transformer with a current rating of 7Amps producing the 5V Vcc for me through 7805 after full wave rectification. Added after 1 minutes...

    Stepper motor circuit problem

    stepper motor power supply circuit The rating of the motor is 5V and it is a 2 phase motor, so i think i cannot give 10V as the supply. Secondly, there is one more point. The current in the Vcc leg of the motor is coming out to be 2A and in the other 4 wires it is 1A. Here i have a basic...

    Stepper motor circuit problem

    stepper motor circuits Hi all........ Here is a circuit below which i am using for controlling a stepper motor through PC's parallel port. The unipolar stepper motor has a holding torque of of 21 kgcm with 2 Amps current per phase. Problem is that i am getting only 1A current in the four wires...

    controlling stepper motors

    I HAVE A BASIC DOUBT. Aren't L297/L298 ICs only meant to control bipolar stepper motors??????? Mine is a unipolar one.

    controlling stepper motors

    stepper motor l297 + atmel I have studied about the logic of controlling unipolar stepper motors. Can anybody tell me how to control them using ATMEL microcontrollers? Plz help me in writing the code for the same.
