Thread: Grave Grabber Motor HELP!

Tweet

At the moment i am building a grave grabber and i need help on knowing what motor to use.

It needs to a low RPM motor as well as being cheap.

The person who made the tutorial used a paint mixer motor, but that seems quite expsensive for my budget.

Please help me...

You have a link to the tut?

Also when you say cheap, what exactly are we talking about?

this tutorial


the price mark...what ever really but not £50+

Try monsterguts.com I used there wiper motors with there 2 amp inverter. The speed that the inverter will slow that motor down to what you want. They are closed right now but will reopen soon. I am going to build one of these as well. I really like it!

Also, if you are looking for a cheap way for a low RPM motor usually you can find cheap motorized rotisseries out there, which is idea for grabbers and depending on the strength of the prop wiper motors are also good too. Scary Terry offers a good tutorial on this.

If, you do go with wiper motors the best power source may be a 12volt wall wart. The lower the voltage the more slower the motor will turn in revolutions. I would never suggest using any car battery chargers the amperage is way too high and likely to produce enough heat to cause even a fire. The lower the amperage the less heat is exchanged.

I also built one. I used a wiper motor but used a 5vdc 1 amp power supply. This slowed it down and did not affect it at all.

A low RPM motor like a Molon brand or similar would work fine for a grave grabber.

Wouldn't a wiper motor be to slow?

IO'd go with a 50 rpm dayton, a rotisserie motor would be way to slow, a wiper motor could be ok if connected to 12 Volts DC, but it also would be a bit slow, I used the 50 rpm for my build and it's about right for the movement.

Troy you have the Dayton Number for the motor? Thanks
