But the circuit setup he uses does not give the motor the power I need.
Would a controller or shield solve this for me?
Basically the DC motor is only meant for 3volts, yet it does what I need with a 9 volt on it perfectly
QuoteBut the circuit setup he uses does not give the motor the power I need. What circuit set up, there are several in that video?
QuoteBasically the DC motor is only meant for 3volts, yet it does what I need with a 9 volt on it perfectlySo are you applying 9V to the motor?See:-http://www.thebox.myzen.co.uk/Workshop/Motors_1.htmlI hope you are not using those small 9V square batteries, they are a poor choice when powering motors.
Yes I am using a regular 9v square battery.
If I connect it directly to the motor it works perfectly,
if I do the above circuit it does have the power to turn the the gears I want it to.

And as Grumpy said, the standard 9v rectangular battery is a VERY poor choice for driving a motor. Yes, the motor will spin when unloaded, but once you put any serious load on it the battery will NOT be able to keep up with the current demand. You'd be much better off using a battery pack made up of enough NiCad or NiMH cells to get the voltage you need. More than likely a 5 or 6 cell (series wired) will do you just fine.
So measure the voltage you are getting across the motor when it is in the circuit with the transistor.
