So i have a peristaltic pump, supplied by my employer. I do not have any exact specifications on the product itself but have found 6V and 500mA of power to be sufficient in running the pump at the speed I need. Obviously this is a very low power motor.
I should preface this, I don't have extensive experience working with circuits. I am a biomedical engineer by trade, and most of my electronics experience comes from working with Arduino in small projects.
To power and control the pump (its just a DC motor), I'm using an Arduino board which only supplies 5V. Therefore, I'm using an SN754410NE H-Bridge to power the motor. However, I find that powering the motor through this H-Bridge not only makes the motor run significantly slower, but also makes the H-Bridge really hot. I'm using a 9V battery, and these observations led me to believe I'm losing a significant amount of voltage through the H-Bridge. Is this a common issue with H-Bridge, or would this be resolved by using a better H-Bridge? If so, does anyone have any recommendations?
Note: I am not use Arduino Shields, so while this may be a simpler solution, please do not provide these links.
Thanks in advance for any help.
