    How Many Volts Are Needed for My Motor to Lift 12kg in a Time-Lapse Project?

    I am working on a timelaps project so I need my motor to move very slowley, the motor I am using has a max voltage of 24V and a stall current of 1 Amp The motor I want to use is on this link: http://www.dynamicperception.com/EZ-Swap-DC-Motor-p/dp-dcm.htm This motor will need to lift...

    Rack and pinion, motor selection method

    I sorry I am doing a very similar thing, could I ask where 18 came from ? "To travel at a speed of 0.3 m/sec pinion will require 0.3 / (n * p) RPSec = 18 / (n * p) RPM."

    Calculating Required Torque for Rotating an Object at 1RPM in 1 Second

    Hi I am trying to work out the torque required to rotate an object from 0 to 1RPM in 1 second (1 second accelerate to 1RMP) , its working in time laps so very small movement is required. The diameter of the gear is 30mm and the diameter of the shaft is 10mm, the object on top weights 20kg...

    What Is the Angular Velocity of a Falling Mass-Driven Wheel?

    AAAHH I'm an idiot I forgot to square root the velocity! so this is correct then?? Vroot2=u+2as Vroot2=0+2x9.81x30 Vroot2=24.2m/s angular velocity ω=v/r ω=24.2/1.5 ω=16.13r/m

    What Is the Angular Velocity of a Falling Mass-Driven Wheel?

    A uniform Steel wheel of diameter, D=3m and mass, 8500kg is supported by a low friction bearing, shown as the large black spot in the drawing. Around the outer surface of the wheel, a light wire rope is wound. From the end of this wire rope, a mass, M=1000kg is attached Initially, both the...
