Hi. I am new to the board and looking for a little help. I have a mechanincal background and am not very good with electrical circuits.
I have a problem I am trying to solve. I am using a Mabuchi 24 VDC motor mounted to a gearbox. When the motor is running under "normal load", the current draw is in the .3-.5 amps range. Under a locked rotor condition, the motor is drawing around 3.5 amps. The probem is that the power source uses MOSFET transisitors that have a 1.5 amp limit. Unfortunately, I have no choice but to use the power source.
Here is my question: is it possible to use a small inexpensive board to limit the power to 1.5 amps? I realize that when the motor is turned on, there will be a very brief spike in the current (inrush current). It would be OK it the board cut off power while the load on the motor was high enough to draw more than the 1.5 amp limit. However, when the load is removed, ideally the motor would start running again.
If there isn't a cheap fix, I may have to search for new sources of motors.
Thanks in advance for you help.
