I recently obtained 3 electric motors.
Two of them came from a Hospital type bed. They look like this. The other one came from one of those lazy-boy type chairs that lift to help people stand up. This one looks like this. I have ideas for ways to use them in magic props such as levitations. I'd imagine others have made use of them as well. I'm just curious as to what others might have used them for. Or maybe there are some plans already out there that use them I could check out for ideas. Also, does anyone know if it's possible to find the "Worm Gear" for them that give it a faster lift?

Ron,
Both photos are quite small. What you are calling a motor is actually an assembly referred to as a gearmotor. This consists or an electric motor and a gear reducer. One type of gear reducer consists of a worm gear driven by the motor and in turn driving a second gear that powers the output shaft. You must bear in mind that if you desire "faster lift" that means selecting a lower ratio. Selecting a lower ratio results in less torque delivered to the output shaft. What needs to be done is to calculate the torque required for the application and size the drive accordingly. Yes, . . . I do this for a living. Regards, Bill Sutter |

I made use of such a motor. I believe it is called "linear actuators". I used it for my gamolo type of levitation. You still need a support aside from this motor. The motor can give the support a push upwards or downwards. It is very strong, silent and works on batteries, too. Mine is 24V DC.

Lou and Jaxon,
Where can I get these linear actuators? Does it have an 8-10 lift? Jaxon, does your's have a "screw" thread shaft like a garage door opener or does it the shaft just go up and down and to what length? I like the 24 volt application. Don't know if they would lift a person. Dr. Solar

A good source for various motors:

Just experimenting. The motor takes the place of the person providing the lift. It works but it's very slow. It's good to find out it has enough power to do that though. Ron Jaxon |

Lou Hilario is right! These “linear actuators” they are used for everything from high-end treadmills to low-riders. They can be found sometimes trough online auction new and used, the used ones sometimes sell for pennies on the dollars. Most of the ones I find are 12volt & 24volt. these would require a transformer and a thing that changes AC to DC. The ones that come of hospital beds may be 110volt AC and would be mare desirable for some applications and would not need a transformer.
Our friends don't have to agree with me about everything and some that I hold very dear don't have to agree about anything, except where we are going to meet them for dinner.
