- Mar 2, 2005Hi Martin,Your correct,I checked and the plate reads 14 amps I guess.I can't get at it very easy during winter as all the heavy machinery is bunched together in a small space I try to heat.That works out to 2 HP but like I said I doubt they would give us a bigger motor without claiming it in the ads.It would be neat for someone to do an amp draw test to check it out running.Thanks for reminding me what the formula is MartinTom Munroe----- Original Message -----From: leasingham_connellySent: Wednesday, March 02, 2005 10:33 AMSubject: [mill_drill] Re: dovetail collum mill drill or mini-knee mill (6x26).

HP.I suspect it isn't a true 2 HP though.It only draws 17amps on
110volts.Is that a 2 HP draw?

Electrical power is the product of volts times amps so 110 times 17
is 1870 watts. As 1 HP is 745 watts this is a power of 2.5 HP. As
some of the electrical power will be wasted as heat and noise the
shaft output will be less than 2.5 HP so 2 HP seems realistic for
this current draw (there is also the small matter of power factor in
AC circuits but that's too specialist for a machining group). Is
this the maximum current draw on the motor's data plate? If you have
measured it at this level with a motor running unloaded then it
would seem too high as the current will increase as the motor is
made to do work. The no load current draw should be well below what
is needed for 2 HP.
