Hi All, I wanted to know what kind of step down transformer ( in terms of power and capacity / rating) have to be used for the spin-x dryer. The specs are as follows 110V/60hz power on power: 600w at 8.2 Amps and runnning power 400w at 5.0 Amps, It has an Induction motor inside.
Well, the "numbers" don't make to much sense to me. Profile has no e-mail, and it says "engineer". 8.2 amps @ 110 volt does not equate to 600 watts 5 amps @ 110 volts does not equate to 400 watts What is a "spin-x" dryer??? John

HotLine1: It's the difference between true power (W) and apparent power (VA). The motor has a power factor of about .66 on starting and .8 running, not unheard of.
Venki: For the transformer, I would size it for the inrush of the motor (8.2 amps, 900VA), or more and remember overcurrent protection as per Code. A single phase XFMR from one of the usual companies (GE, Square D, Siemens, etc) should work. But, as I think Sven was saying, why not just run a dedicated 110 circuit and elliminate the trouble from all the extra equipment. I would think it should cost about the same (assuming reasonable access).

It's one of those external spindryers they had back in the 1950:s. I thought they disappeared when washing machines with built in spindyers were introduced. www.spin-x.com
According to the site, this spindryer spins at 3300 rpm. The site tells you that that washing machines spin at only 500 rpm, something I find hard to believe. I remember selling 1200 rpm machines a few years ago, and I think the latest models have 1500 rpm spin. (The integrated washer/dryers have very high rpm, to minimise the load on the dryer part)
I wonder what the clothes look like after a 3300 rpm spin.

When I was a child (1980s) some of the coin-op laundries here in New York had something like that. It looked like a HUGE pressure cooker on a pedestal. You'd put a quarter in it and it'd take your clothes for a spin...so it would shorten drying time.
Haven't run across them in years. I used to love hearing those things start up and watch them rattle as they did their thing. They looked scary!!

Thanks to all who have been replying to my email.. Well I am an engineer but a computer Engineer and Have no practical experience in Electrical field. Also This spin-x dryer I used it in my APT where we used to wash baby clothes and hang dry them on the clothes line. The Clothes are in a perfect good condition without any damage. So I guess from all the answer I get .. Like to get Transformer or 60Hz unit will not work on 50Hz .. Etc etc .. I will have to sell this unit ... I guess I will logon to some auction site and advertise it there..
