No I'm not going to use a car wiper motor for this project. I gust want to know so that I can compare its torque with DC geared motors available on ebay.They will be rather large, going from size of motors for scale, your arm looks to be the size of a human arm or kid's leg.
What are the disadvantages please?? so is using 1st class lever more efficient??The 3rd class lever moving the first section around the anchor is a disadvantage as noted earlier
I want the dimensions to be approx 30cm for the first section and 20cm for the second section (please see attached diagram), therefore the load can be lifted at about 50cm far from the base.How far do you want to lift it?
I was planning to use PWM to very the speed. Ideally the maximum speed will be that similar to the video in the link below.How fast do you want to lift it?
That uses standard R/C Servos, nowhere near the torque of a wiper motor.
Yes, but the energy expended lifting a load will be less than the energy required to compress it again. If the purpose was only to lower heavy objects to the ground, gravity would help compress the strut again, if it is to lower while compressing the strut without a load, the power of the needed servos would be greatly increased.Hi, thanks for the replies.
I was thinking, can in any way a gas strut help the motor in lifting the load??
