Hi Everybody,
I am not an expert in electricity, but i need to design a circuit for mechanical use.
I have a very basic knowledge on H bridge.
I need to implement an H bridge circuit which is capable of changing the rotation direction from forward to backward and vice versa, every 5 seconds.
My input is a sinusoidal with frequency of 0.1 HZ, Amplitude of 1 volt , which changes between 0 to 1 volt.
my DC motor has a resistance of 10 ohm, constant velocity of 1500 rotations per minute, and terminal voltage of +/- 10 volt.
In addition, i need to protect the motor in case that the current exceeds 1A, only for time period of more than 10 msec.
i can use a one 12 volt power supply, amplifier that can be used as comparators (LM324), 4 power transistors (2N6059) for the H bridge, and resistors,capacitors,inductors and logic gates.
i will appreciate you for any information you can give me to start with.
