loneronin Posted February 12, 2018 Share Posted February 12, 2018 (edited) Saturday at a market I bought this electric fan that was part of a boiler. it works at 220V, I tried it works well. I would use it for my forge. I would have the advantage of not having to turn the crank any more. I will have to make a small frame to hook it to the forge table and I thought to add a gate in front of the suction hole to regulate the air flow. I also wondered if it would be possible to add a motor rotation speed regulator. I think of the classic light dimmer for example. risk of burning the motor according to you? does it take a particular regulator? [2000W 220V AC SCR Electric Voltage Regulator Motor Speed Control Controller] regulator would be better than the dimmer? First thing I want to avoid burning the motor!

Steve Sells Posted February 12, 2018 Share Posted February 12, 2018 use the regulator, many have used the dimmer controls but most of them ruin the motor after a while. Quote Link to comment Share on other sites More sharing options...
loneronin Posted February 12, 2018 Author Share Posted February 12, 2018 Thanks Steve! the regulator I posted is the right one? it's very cheap but seems to be 220V AC, 2000W while my blower is only 60W. I presume the regulator works fine till 2000W Quote Link to comment Share on other sites More sharing options...
loneronin Posted March 26, 2018 Author Share Posted March 26, 2018 frame for my forge done! it can be attached and detached from the forge in one second. I put a switch on it and the blow power can be easily tuned with the sliding door. Quote Link to comment Share on other sites More sharing options...
holder Posted April 14, 2018 Share Posted April 14, 2018 I got an electric air mover from Amazon. Hardwired a 16 ga. 25 ft extension cord to it using a power strip as a switch. Plugged the male end into the power strip, flipped the switch on and it blew like a small hurricane. Then I got fancy and attempted to wire a variable speed switch between the motor and power strip. When I flipped the switch again I got a nice flash from my vari speed switch but the motor kept running. My wife tripped out with the flash thought the house was burning down. I then read the instructions a little more carefully, they said "Some configurations require an EARTH ground, so a ground wire is not included with this switch." The ground point on the switch wasn't even identified. I had to laugh. I was out $20 for a switch and was set up for failure from the Get Go. The sparks were kind of pretty though. I'm using dimmer switches from Home Depot from now on. Cheaper and easier to get. Oh and I'm grounding to the motor case next time. The switch might still blow but sooner or later I get it to work. My motor is only a 120 VAC motor. I think a dimmer switch would work without burning up the motor. I plan to have it vary the input voltage. The frequency, 60 cycles should not be effected by the dimmer switch. The resistor should only drop voltage not change frequency of the input. Now if there were an output voltage from the motor, the speed of the motor would determine the output frequency. Quote Link to comment Share on other sites More sharing options...
Steve Sells Posted April 14, 2018 Share Posted April 14, 2018 Oh Lord have mercy <shaking his head in dismay> Are you going to tell us about the time you stuck your finger in the wall socket next? We try to teach proper and safe operations here, and you just blew that all to hades, the instructions also included a statement of .. only to be installed by qualified personnel, if you were qualified you would have known about the ground wire location Quote Link to comment Share on other sites More sharing options...
SLAG Posted April 14, 2018 Share Posted April 14, 2018 Herr Holder, Please do not try to qualify for next year's Darwin award. Leave it up to member's of other internet sites. SLAG. Quote Link to comment Share on other sites More sharing options...
holder Posted April 14, 2018 Share Posted April 14, 2018 I worked on and taught troubleshooting and repair of Mobile Electric Power Plants in the Navy for about 20 years. 120 VAC 400 freq, 220 VAC 400 freq, 440 VAC 400 freq. Also developed computer based training for the Military on the same gear. But I suck at house current. I'll figure it out with a little help from my friends on IFI.

Glenn Posted April 15, 2018 Share Posted April 15, 2018 If you can not fix it with a hammer, then it is an electrical problem. May want to consult a qualified electrician for his skill and expertise, not a blacksmith. Quote Link to comment Share on other sites More sharing options...
