Good actuators

anyone recommend me a good actuator for a vertical crusher?

Re: Good actuators

A well engineered home made one is always going to be a better solution

Re: Good actuators

good paint gary, what would you say a good motor is for one? something a bit better than a drill motor but not overly sure what

Re: Good actuators

Well what is your budget? The ideal is something with a huge amount of torque like a magmotor (think they're called ampflow motors nowadays) but one of those will be around the £250 mark!

Re: Good actuators

forgot that bit, a magmotor would be nice, but it would cost more than the robot

i would way about £50 for the motor, would be great to have a massive motor but I cant really justify much more on it

though what about the E-150 mag?

Re: Good actuators

speed 900 or speed 900 clone.

job done?

Re: Good actuators

but could that actually crush, or just grab?

Ive got a actuator but I honestly dont know how well it would work for a vertical crusher

Re: Good actuators

crush

Re: Good actuators

recommended gearing for a crusher?

Re: Good actuators

You mean ratio? Well as crazy as you can get without it being so slow it's useless. Greater reduction = more torque = more crushability.

Re: Good actuators

it depends on the pitch of the rod you're using. you'd have to work out a good mix between crushing ability and speed. a speed 900 on 24v will give plenty of power, the main challenge of building an effective crusher is getting a sturdy enough frame.

Re: Good actuators

That's why I am thinking a commercial actuator as getting all the ratio correct and pivots will be very difficult, might try and find a alright 12v actuator and run 18v through it
