Motor Destroys Output Stage Transistor And Then Everything Works Fine
anyone ever see a problem like this?
I am guessing that there is an intitial overcurrent condition during start up(this typically happens as soon as the motor operates under load for the first time). After I replace the output transistor everything runs fine. Thanks much, Ed |

After I replace the output transistor everything runs fine. Or an inductive spike. A bit more info would help. What type of motor? What type of driver? --- sam | Sci.Electronics.Repair FAQ Home Page: http://www.repairfaq.org/ Repair | Main Table of Contents: http://www.repairfaq.org/REPAIR/ +Lasers | Sam's Laser FAQ: http://www.repairfaq.org/sam/lasersam.htm | Mirror Site Info: http://www.repairfaq.org/REPAIR/F_mirror.html Important: The email address in this message header may no longer work.
