When power is transmitted by a shaft, the power can be calculated as the rotational speed multiplied by the torque.this is a snowblower build, I was planning a 40hp Kohler with a 26gpm at 2500psi pump to power the hydraulic snowblower.
I want to make this set up Electric with a generator.
But if you do follow what we're saying, you know it doesn't work that way. If you put the 15 HP output of the electric motor through any kind of gearbox, belt drive, chain drive, hydrostatic transmission, or whatever, you only get (less than) 15 hp out.I can follow what your saying...right up to the end lol.
The blower wants to be driven at 600 rpm. The 1800rpm electric 15 hp motor...would be 3:1 speed reduction.
I would really like to hear “yes Jason, your 15hp motor reduced 3 fold is about 45hp, and a 8kw generator should be sufficient for your needs”...that’s what I want someone to say lol. Because that means it will work. Lol
Right - the electric configuration is reasonably straightforward, and requires the same size of engine as the hydrostatic configuration, but a big generator is expensive (unless you get parts salvaged from scrapped EVs). Hydrostatic drive components are cheap and compact compared to electric, for the same power, in a moderate power range....
I was hoping I could simplify things by buying a PTO drive blower and putting an electric motor on it, and powering it with an appropriate generator.
but the way it is sounding is...the motor will require such a large generator that it will off set the costs of the hydraulic power unit.
Unless I am missing something....the electric route will be unfeasible relative to hydraulic.
Why when you can bolt a hydraulic pump directly to the PTO of your transmission?Yes I am building this from scratch. I don’t have a blower yet...but I am thinking of the WoodMax SB-85 (85” width). It is PTO driven and 3 point hitch carried. I am installing this unit on the back of a 2020 Ram 5500.
The blower has a pto hp rating of 25hp-65hp lol. So there is plenty of room, but the more the marrier. I was going to power the blower with hydraulics (essentially buy a hydraulic snowblower of the same width), but I would much rather do electric
