[QUOTE="Geo2, post: 161662, member: 4572"] Agree with G0lddigg@, if we talking about power needs for a trommel the perfect combination would be a low RPM high torque motor. But in the case of bellow type dry washer, then you need the speed, so a high RPM motor is required to lift the bellows quick enough to allow air circulation. Since bellows are not that heavy a high torque won't be needed and I am talking about portable dry washers that is one person can handle. Another point to consider is the low power consumption, a high torque motor requires more juice to run ;) That means lugging a heavy Battery which is not you need to do especially in rough terrains. Smaller motors which can handle a small portable dry washer will not consume a lot of electricity meaning less weight to carry in the field. It's a kind of compromise, so to speak. Good Luck.
