This is a low inertia motor that can be powered from a suitably rated solar cell. This is because these motors have a starting current of just 30mA at 0.5V.

The motor works from a voltage in the 0.5V to 3V range.

The motor has red and black 150mm flying connecting leads.

Features:

  • Low inertia ideal for using with solar power.
  • Low starting current.

Contents:

  • 1 x Low Inertia Solar Motor – 1820 RPM.

Dimensions:

  • Height: 12.8mm.
  • Diameter: 24.4mm.
  • Axle Length: 10.55mm.
  • Axle Diameter: 2mm.

  1. Jonk –

    We were needing a small motor for a ferris wheel on our model railway layout and this one fits perfectly!

    Answered by the admin Hi Duncan, I would recommend the two low inertia solar motors, preferably the 1820 RPM one as that should be the one that will work the easiest. Best Regards Cullen

    Answered by the admin Hi Graeme, Yes this should be suitable, attached the multi meter to the wires, set it to measure either current or voltage and spin the motor (or use a fan blade and blow on the fan). Similar to this, https://www.kitronik.co.uk/blog/experiment-7-wind-power
    5. Hi, if I would like to power this motor directly from the microbit, is that possible or will there be to much current from one pin and damage the microbit.Could I connect black to ground and red to a GPIO pin and for example set digital pin 1 to 1 to make it start?

    Answered by the admin Thank you for your question, it would not be possible I am afraid, it is not the Voltage that would be a problem but the current draw as the micro:bit is not able to output enough current from a pin to supply even this low power motor. You would need a separate power source. Best Regards Cullen
    6. I would like to use this motor in combination with a raspberry pi. More specifically I want to adjust the speed of the motor using pulse width modulation (PWM). To do this I need to know the value for the herz parameter for the PWM. My question is thus: What is the range of usable herz values for this motor? Thanks in advance for any help!

    Answered by the admin Hi MuadDev, It is possible to calculate the hertz from the RPM by dividing the RPM by 60. The starting speed for the motor is 1000RPM so 16.66 hertz and the Speed at Maximum Efficiency is 2000RPM so 33.33 hertz. I hope this helps.

    Q What is the torque of this motor? Thanks :)
    Asked by Anonymous on November 27, 2017 12:00 am
    Answered by the admin Hi Samuel, The motor has a torque of 3.03 g.cm, when powered at 2V, and draws 62mA which is the max efficiency of the motor. The torque at the point the motor stalls is 12g.cm.

    Answered by the admin Hello Sanjay, The motor has a starting speed of 1000 RPM at a 0.5V supply, and spins up to 1820RPM at 3V. However we don’t have any data to say what the motor will spin at when supplied with the voltages you have stated. The speed should however progressively increase as the voltage is increased.

    Asked by Anonymous on June 9, 2015 12:00 am
    Answered by the admin This motor spins at 1820 revolutions per minute, so it might not be the best motor for what you are wanting to use. We do a small 3V vibrating motor, these motors are often used for silent alert functions in mobile phones, the product code is 2541
