Question:

I am a primary school teacher who lets the Year 6 girls make electrical toys of their own choosing incorporating motors LEDs and buzzers. This years crop have been particularly challenging but we have got all functioning except for the one girl who has chosen a jack in the box. Is there an easy way to change rotary to linear motion? So far we have rigged up a small motor and a couple of rods as shown by Norma Kraft on this web site http://functionspace.org/topic/3704/Converting-Rotational-motion-to-Linear-motion-and-vice-versa. The girls "jack" is made of felt and only weighs 9g but it seems too heavy for my little motors. Would your high torque one manage that? Thanks

    We don’t sell any linear motion gearboxes or any other product that is suitable for your design. The motor might work however it would be difficult to be sure. It will depend on the lever lengths, angles and friction coefficients, it will also depend on how much force it will take to turn the axel.

Question:

Having stated this is a "high torque" motor, could you please give me an idea of the maximum and minimum torques generated? Thanks, S

    Hi, at 3V this motor has a minimum stall torque of 110.0 g/cm. If you require more toque this can be acheived through gearing.

Question:

If using a small solar cell (for modelling) which motor would work better ? A low torque or High Torgue? Thanks Gary

Answers:

  • Posted by Aaron Sturman on Thursday, 19 June 2014
    Solar cells do not generate much current at all so you need to use special motors with very low starting currents such as our product code 2506. These tend to have very low torque but spin very quickly so gearing is needed to get them down to a reasonable speed.

Question:

Is this motor suitable to drive a small bbq roasting spit powered by 2x1.5 batteries.? Thank you, Eddie.

Answers:

  • Posted by Geoff Hampson on Tuesday, 5 April 2011
    I believe that the motor should be ok. I believe you will have to use some form of gearing to slow the rotation as I doubt you will want your spit to rotate at 7930 RPM which the motor does under no load.
