Hey group
I have bought a small hobby motor with the following characteristics.
Torque: Low
Operating Volts: 1.5- 4.5V
Nominal Volts: 3V
Speed (no load): 12000rpm
Current (no load): 0.28A
Speed (max eff): 8540rpm
Current (max eff): 0.69A
Torque (max eff): 7.94gcm
Size dia: 20mm
Size length: 25mm
Shaft length: 8.1mm
Shaft dia: 2mm.
I would like to run this of a Basic Stamp, BS2px in particular. The
datasheet for the BS says that the I/O pins each can source and sink
30 mA. Therefore I believe there is not enough current to run this
motor direct from the ic.
I only want to be able to turn the motor on and turn it off. It will
be used to create vibrations. ie like a mobile phone.
Is a mosfet the best way of isolating the motor from a chip or is
there another simple solution?
Thanks for any help
