Sometimes you're dealing with apples and oranges and pickles and you can't do direct comparisons but here are some basics:
HP = T x RPM/5252
Where
HP = HP
T= torque in ft-lb
RPM = Rev per minute.
and
1HP = 745 watts
1 watt = 1 volt x 1 amp.
thus if you have a 1hp motor and it is runing on 12 volts, at peak power it consumes about 62 amps. If it were 1hp and ran on 120 volts, you'd be looking at 6.21.
Thus, a DC motor makes absolute peak torque at stall but NO horsepower (do the math)
However, the amount of torque is a function of how much current flows thru the windings of the armature times the number or turns of wire. Suffice it to say that 20 turns of #22 wire will NOT make as much current as a comparable armature with 20 turns of #16 wire, assuming it will fit and was running at same RPM (or, oops stall).... |
