What is the HP for this motor?
Hi,
I have an old craftsman motor lying around. I checked the spec label and it does not list the HP but it list other info. Can someone give me an idea of the HP for this motor? The info for the motor is: V 120 A 7.9 1725 RPM HP w0486 Thanks Alex |

The HP w0486 or: .65 hp. Leif |

Old ones tend to be less efficient; so somewhat over 1/2hp. |

The info for the motor is: V 120 A 7.9 1725 RPM HP w0486 Thanks Alex And yet another way of estimating the motor power: Rated Input power is 120v * 7.9a = 940 watts (an estimation since this is an AC inductive load) Assume 50% efficiency ( to account for mechanical and electrical inefficiencies, power factor, etc.) = 940 * .50 = 470 output watts. (pretty good match for the 'w0486' HP entry assuming the 486 is the motor power stated in watts) HP (est) = 470/746 = .63 So we are in the 1/2 to 3/4 HP range. Tom Veatch Wichita, KS USA |

Or, in Craftsman terms, Maximum developed horsepower is 2. |
