If you mean for an electric gokart, I don't think it is built for continuous duty. I think it was built for short duty, ie starting an IC engine. Mike

Just expressing our individual opinions. http://www.diygokarts.com/vb/images/editor/smilie.gif And if you had two 1000 watt motors I wouldn't want you to avoid using them because of what >I< consider improper information. I did this yesterday and the motor drew 100 amps + or - a few amps...

It certainly would, it's a DC motor with more load, it will slow down The kids cars I have seen all use a separate motor on each rear wheel, it works for them and the are built as cheap as possible. http://motorizedcarsforkids.net/ We're talking about turning a corner, this doesn't...

Hi guys, Anyone running two engines with separate axles? In other words not a solid axle to both wheels. In another thread someone suggests that it is a problem to have a motor on each wheel. Mike

You guys have anything to convince me that a motor on each rear wheel is a real problem? I don't see it as a concern. The inside wheel will get pinched down by friction and slow down, the outside wheel go faster because of less load. If you have any references about this, please post them. I...

Ya, It was more a general question than specifically about my motor. I have a bit of an odd setup. I came across a free separately excited field motor. But my motor controller is for a series wound motor. I just fixed the field current and drive the armature with the motor controller. I don't...

Hi HelloYOU, I agree with your statement, so it seems if the motor is run at a lower voltage the back emf is lower which would cause more current to flow, but, there is also less voltage to push the current against the lower back EMF. Is there anyway to get a better estimate of power other...

What controller do you have? Mike

The math works out that if you run this 95 volt motor on 48 volts the power is about 25% or around 500 watts. If you lower the voltage the current will be lower. So in order to calculate the actual power we need to find the R or resistance of the motor. If we use ohms law V = I x R and...

Is it a standard AC/DC motor designed for 60 hz or is it designed for a wide frequncy range? Any links for the motor? Thanks, Mike

I'll hold the record for now, I'm 54 and 359/364 yrs old. Mike

I think that would only be the new style induction stoves. I think that's backwards, you want a fixed frequency variable duty cycle. I did it for a coil winder too, I wound a 40" long by 8" diameter coil for tesla. One of those projects I need to finish. Mike

I have watched that motor you listed, but the seller warns "This motor shaft is not designed for radial loads." This means the bearing is not designed to have a sprocket mounted on the shaft with tension from a chain. I also wonder about the duty cycle this motor is designed for. It's designed...

Whats? The proper spelling is watts. Only insignificant if you provide proper heatsinking. Try holding a 100 watt light bulb. Yes, because dissipation in the device is I^2R. I just didn't do the math in my last post. You also spread the heat over more area when you double the number of...

It is not the only difference! If you have have 100 amps through 4 FETs that is 25 amps through each. If you go to 8 FETs the amperage drops to 12.5 amps through each FET. The heat developed in each FET drops to half. Mike
