How can this be? (Electrical Question)
I'm looking at electrical chain saws, a Poulan and a Husqvarna.
Brand Poulan Husqvarna Item Number 118147 328965 Bar Length (Inches) 16.0 14.0 Amps (Amps) 13.5 13.5 Horsepower (HP) 3.5 9.7 They are both 13.5 Amp saws, but the Husqvarna gets almost three times the horsepower of the Poulan. How is this possible? Also, the Poulan costs about $75, the Husqvarna about $270. |

Nah, and i don't believe the 3.5 and 9.7 either. not on a 13.5 amp motor. Maybe .97 and 1.35... that would be more realistic. i know what you're saying though. Yes the gearing might make a difference, and I would think that the Husky would have a slower chain RPM. But also one reason they rate a higher hp is the shorter bar. The Husky would be a better saw, but IMO, not a $200.00 better saw. |

How is this possible? Also, the Poulan costs about $75, the Husqvarna about $270. Manufacturers of electric tools play a lot of games with horsepower. It's really very simple however. watts = volts x amps = 120 x 15 = 1800 watts from a typical 15 amp circuit 1000 watts = 1 kw = 1.34 horsepower at perfect (100%) efficiency. Therefore the absolute maximum horsepower you can get on a 15 amp circuit is 1.8 x 1.34 = 2.41 In reality you'd be lucky to get 2 hp at normal efficiencies. Gearing has nothing to do with it, hp stays the same, RPM and torque change. |

some neat things about an electric chainsaw is 1. they're light 2.
great if you just have some yard trimming to do 3. quiet -(well, sounds like a circular saw but not even that loud.) good for noise restricted areas, 4. no mix fuel. 5, fuel doesn't go bad in them and they're easy to start. plug in and pull the trigger. 6 They're cheap. bad part is unless you get a cordless one, you are only restricted to the length of your extension cord. |

Luckily, my house is about in the middle of a lot 200' long, so a 100' cord ought to do quite well. |

My pocket reference says a typical 1HP motor will draw 13 to 16 A at full load. This falls right in line with what Wayne presented.

I've got a Remington coming in the mail from southern Illinois. Tim even cranked it up over the phone for me. The damn thing sounded like an F-16 buzzing his shop.

You're right. They were resurrected by MTD and it looks like the pre-2009 parts will be available for a while. http://www.remingtonchainsaw.com/ |
