The reason is because amps produce torque.
To add to this...
I think I did not understand at first the reason you wanted to know how many watts the G110v2 was rated at (none is given that I know of).
Here are the formulas and info I was searching for and want some input if you can (any electrical gurus PLEASE feel free to chime in):
Electrical power is in general rated in Watts or Horsepower.
A
horsepower is a unit of power equal to 746 watts or 33,000 lb.ft per minute (or 550 lb.ft per second).
A
watt is a unit of measure equal to the power produced by a current of 1 amp across the potential difference of 1 volt. A watt is 1/746 of 1 horsepower.
Even if the watt is the base unit of electrical power, its common to rate motor power in either horsepower or watts.
Power in Watts
Electric power of a motor can be expressed as:
Pw = ηm U I (1)
where
Pw = power (W, watt)
ηm = motor efficiency
U = voltage (V)
I = current (A, amps)
Power in Horsepower
Horse power of a motor can be expressed as:
Php = Pw / 746 (2)
or
Php = ηm U I / 746 (2b)
where
Php = horsepower (hp)
So, you were wondering about
watts in relation to
horsepower ratings, not watts as an
equivalent of amps x volts = watts... right?
If you are an electrician (or anyone else out there is), or if you just happen to understand these ratings better than me...
Please help me to understand the red highlighted specs below:
CYCLO MODEL 5 ELECTRIC SPECIFICATIONS:
Power Supply: 115 Volts, 60 Hertz,
220 Watts
Motor: alternating current, semi-enclosed 24-bar commutator, Speed: 3000 orbits/minute,
Output: 1/3 H.P. (.25 Kw)
Weight: 6.5 lb. (2.9 kg)
Head Rotation/Diameter: clockwise/4"
Electric Cord: 10' length, 16 ga/3SJTOW
Housing: heavy-duty cast aluminum
I am a bit confused on the Power Supply rating of 220 watts, as it seems to me to mean that only about 2 amps is needed to run this machine (volts x amps = watts). I definitely think I am confused here.
I think I am understanding that the output of the machine is 1/3 horsepower, so that should equate to about 248-2/3 watts.
Thanks!
