Hi All,
I'm working on an electronic project that needs to run a DC motor at a constant speed (only start stop operation needed from motor). I have found a motor (Namiki 22CL-3501PG) which suits my torque requirements. My power source will be 2 AA rechargeable Batteries (ENERGIZER NH15-2300) which i'm planning on connecting in series to get 2.4V input voltage. I just need to find an appropriate voltage regulator to supply the motor with 12V and I was wondering what's the best way to go about doing this design?
Questions:
1. Would I need to find a regulator that can supply 12V with an enable signal and control the enable with a micro controller to turn on/off the motor?
- if this is the case, in the motor specs it says stall current is 1.8A, would the regulator need to be able to supply all of that current at 12V? I have not been successful in finding any boost DC/DC supplies that can supply 1.8A @12V with a 2.4V input.
2. Would I need to run this motor via PWM?
- if so then what's the best way to generate the PWM at 12V? I'm using a PIC micro controller with 3.3V input voltage.
