Is the rotationl speed variable? i.e. higher RPMs with higher voltage from solar panel?

I agree with the previous answer, the more direct sunlight (solar power) the faster the fan will rotate. I presume there is a maximum rotation speed also regardless of the power applied/supplied by the solar panel. It is a nice unit, quiet and keeps my attic cooler.

Yes. The brighter the sun the faster it runs. You can hear it slow down and speed up again when a group of clouds moves over.

Yes, it is variable. You should buy a PMW controler to vary the speed. But be careful if you need to reverse the motor with a polarity reversing toggle switch. Put the motor leads on the toggle switch, not the power leads.

Yes, gives voltage for solar output, both voltage and amps when battery mode is selected. I have nothing connected to the load terminal.

Mine does not say, nor does the on-screen "properties" window state the RPM. Sorry.

No. The device in not that complex. It is a fied rotation of 360 dgr per hour. The max rotation is one hour.

I got mine upto 12.7 mph on 24v. The motors burned out. I've tried them all and the original PW motors hold up best.

Does anyone know what the rotational speed is? I can't find it in any of the spec listings.

It's variable speed. Had it for approximately a year and save $100 a month on electric bill.

According to the literature the GEARING is from 9 RPM at 661:1 (9 x 661=5900) to 88 RPM at 71:1 (71 x 88 = 6200)So the motor RPM seems to change depending on the Gear Loading. It averages 6000 RPM.It's also rated at 3 Volts. So a 2 Cell AA Pack Battery, or a 3 Cell Nicad, or a single cell LiFe should work.I'm adopting a single cell LiFe with a Solar Cell from a Security Light Pack to try to do the job that Iwanted it for.

Yes, speed adjuster on remote. Noticeable difference when using battery vs ac power much slower with battery. To be expected though

It is at a constant rpm that does not vary with electric draw nor is there a way to manually adjust. I used this generator with Hurricane Sandy outage and was very pleased. With low to moderate power draw was getting over 12 hours between gas refilling.

Thank you for your question. The 1380 SLIM is not variable speed. If you have further questions please feel free to contact our Bosch Customer Service Representatives at 1-877-BOSCH-99 (1-877-267-2499)

I assume with power plug out of supply out let, then you can rotate wheel easily. If so check power supply specifically voltage and frequency. (You can do this by plugging into a source that powers another motor at correct speed. It is hard to wire a motor to run at wrong speed they typically run on do not run. In any case I do not think you should use it if the speed is not correct. High chance to damage motor and/or the operator.

Not sure....I don't like using variable on fan motors...it tends to give them a short life span....the two speeds are adequate, however I always have it set to high speed.

I don't own the Proxxon variable power supply but my best educated guess is- since both speed controllers are essentially the same electronics i.e, cutting off the rectified AC wave cycle at a particular point in time, either the motor or the power supply dial must be turned all the way up and the other dial used as speed control. You should also be able to set lower ranges of speeds of the motor if the power supply dial is set to something less than its full voltage therefore creating a lower speed range available with the motor control dial.Hope this helps. Be safe and please wear those safety glasses at all times when using this tool !

I used a variable speed drive that I plugged my fixed speed grinder into.A fixed speed grinder turns much to fast without using something to slow down the RPMs

Mine is a 371 and is not variable speed. If I remember correctly when I bought mine there was another model that was variable speed. Maybe it was the 371K. Anyway the thing gets hot with continued use. "Continued" meaning 3 minutes or so. Good luck!
