    What is the optimal voltage for a stepper motor?

    Hello All, I am a ME student but, I'm trying to teach myself EE. I am testing out a stepper motor. Here are the specs for the motor: Rated Voltage: 5.7V Rated Current: 1A per Phase Resistance per Phase: 5.7V I am using 15 VDC and want to make sure I don't blow the motor. Using Ohm's Law...

    How Does Kirchoff’s Voltage Law Apply to Supernodes in Circuit Analysis?

    Hello All, I am trying to teach myself basic EE. The textbook I am using gave the following example: 1. Find IS2. Diagram is attached. Given: IS1 = 2A I2 = 3A I3 = 2A I4 = 1A I5 = 0A The answer in the textbook is 1A. My Method using KCF: IS1 + IS2 - I2- I3 - I4 -I5 = 0...

    Powering a Micropump System: Solutions for 100 Volts

    Hello All, I am trying to figure out how to power a micropump system that requires 100 volts. I looked at some current micro batteries, and their voltages range between 2 - 4 volts. I am confused on how to provide enough power. Do I just use several batteries in series or use a voltage...
