Thread: Motor Question

There should be a name plate stating the following : VOLTAGE AC or DC,RPM some will say CW or CCW meaning clockwise or counter clockwise rotation, AMPS or WATTS this is how much current the motor will use, smaller is better, but there is a trade off, some will list the HP. There should also be a part number. The "60 cycle" you refer to is related to AC power and unless it shows a different number you will be ok. Larger motors will get into FRAME designations and other specs. Most of what you described can be made using a wiper motor. One other consideration for DC motors is a power supply, if you use a lot of motors you might be better off getting a regular power supply that will handle the load. Hope this helps.

When i called Burden Surplus, they also helped with the ordering of the wall warts I purchased to power them.

Did you purchase the wall warts from Burden? I'd like to find connectors so that I don't have to hack the power connectors on the motors.

Thanks,

Yes, I did purchase the wall warts from Burden. Essentially, if you unclip the hasps of the motor casing, you can take out the two leads which are already separated. I then simply soldered a wire onto each connector with some heat shrink tubing around the connection. I didn't have to modify the motor casing at all. Something I toyed with was having the motor run to a block where I could then connect the motor leads to the block along with some lighting leads. For this year. The wart probably has more than enough power for the motor and some small lighting like LED's but that is outside my actual knowledge so I might play with it during the off season to get an idea.

Thanks for the info, I'm going to do the same thing since I have some DC warts I can try. I didn't want to start ripping my new motors apart already. I'm thinking of several new props where these should work great.

I want to make some rat peepers and a Haunted Grandfather clock has been something It may work nice for. They're very quiet.

Just wondering if anyone else can suggest places to get electric motors with some torque?

I'm looking for a motor that can spin around 60 rpm with enough power to turn 3 lbs of wood on a dowel.

I've looked at Burden Surplus Sales but I just don't know enough about motors to know what would work.

TK421,
How are you trying to spin it ? if it's on center and the weight is balanced you won't need a lot of torque. If the 3lbs is off center and not balanced it could take a huge amount of torque. Another thing to look at on motors is the duty cycle. Some motors are not made to run constantly only part of the time.

try a junk yard look for a 4x4 shift motor from a ford truck, lots of torque there
