    Hi all!,
    I'm very much so a beginner among the world of small electrics, EVERYDAY I LEARN SOMETHING NEW AND SOMETIMES ITS ALL JUST TO CONFUSING AND FARE TO MUCH INFORMATION TO UNDERSTAND AND TAKE IN.... :( :( :(

    So I thought id just ask someone here and hopefully someone can shed some light on my best options!
    Below I have copied & pasted the specifications which "JAYCAR" provides on there website about a DC electric motor I bought in store.... I hope the specifics i supplied just below are adequate for someone to be able to find a solution for my problem.....

    Standard (High Power) D.C. Motors 9700 RPM
    YM2776 RRP $14.95

    Astonishing speed and power from these compact ferrite magnet types. All units feature hard steel drive shafts, long life design and are built in an ISO 9002 quality environment.

    • Operating Range (V) 6-18


    No load
    • Voltage (V): 12
    • Speed (rpm) 9700
    • Current (A) 1.3

    At Stall
    • Torque (kg.cm) 6.0
    • Current (A) 57

    At Max Efficiency
    • Efficiency (%) 73
    • Power (W) 52
    • Speed (rpm) 8490
    • Torque (kg.cm) .60
    • Current (A) 6.0

    Dimensions
    • Diameter (mm) 42
    • Total Length (mm) 85
    • Shaft Length (mm) 19
    • Shaft Diameter (mm) 5.0
    • Mounting Thread M4

    THANK YOU!!!!
    Ohh I dont know if this will make any difference to a suggestion someone may post the power coming "IN" is set up via a 240V AC adaptor which outputs at 12V DC at 5A

    For a brushed DC motor, you would normally use pulse width modulation, switched through a MOSFET, like shown in this circuit.

    So what are you looking for exactly, did you consider the $5.00 drive answer in your other post?
    This is basically a ready made example as shown by cmartinez.
    Max.
