Soup up a 24 V. Scooter...

The discussion forum on this site should be able to help...

Thank You Lots & Lots... I'm Keeping the Link & Info. To Use Soon!

24 VOLTS. 36 VOLTS: makes me think you have a scooter with a DC motor. But what type: series, parallel. compound, with permanent magnets, brush less?

What kind of scooter are we talking about? How fast? How long are the trips? What is the "parcours".

We also do not know how big your current motor is and also not what type of build it has: Help !!!! From you in the first place.

See Previous Response, by Solar Eagle. I believe it is a Standard Replacement. So ... I'm wondering if, a more powerful Motor is available. I Don't know what any of the spec's are. Or configuration. I don't even know what the power loss would be, by putting larger tires on, or any speed incress.

50% increse tire: 10" Dia. Tire + 50% larger = 10 X 3.14 = 31.40 Cir. / 2 = 15.7"

+ 31.4 = 47.1 Cir. That would only increse the 5 mph to 7 1/2.mph (less power loss from inlarged tires) I think Gearing up will also cause power loss. I'll sacrafice low end for top speed, wilfully! Not knowing what the gearing is, or how to increse it.

With the Previous Link, I will try to contact the Maker. ( They will say: Any modifactions will deleat the warinty... ~ Like I Care.)

Thank you,

About 20 years ago we had a similar problem with robots we manufactured. We ended up with destroying the gears after we put high power magnets (Samarium cobalt instead of ferrite) and thicker wiring in our motors. We had to rebuild the gear boxes too. At the end you pose the question: what is left?

I think the manufacturer in your case chose a motor for its product. Finding something more powerful with the same flange will be difficult.

When you have a work shop available to match the gears, a different motor must be a challenge and probably exists. If the space is there, go for a bigger diameter and a different gear ratio.

Would a larger Dia. tire, increase speed, or lug motor, causing a slow down?

Would a Smaller Dia. Tire increase Speed, by allowing less lug?

Understanding: No resistance; motor still has its limit, of r.p.m. & Torque.

I have tested a scooter with 2 wheels - 12 Volts - and an ample 50 Watts motor. The wheels have each 2 industrial bearings and tires, comparable with regular bicycle tires. On a flat road the max speed was 7 Mph. The weight of the scooter was 12 kg, batteries included, and my weight is 84 kg. A larger diameter thinner tire wheel of good quality will definitely increase your speed. Also getting rid of the gear box and fixing the drive with a chain (mine was only 1/4 pitch) and replacing the motor by a multi pole type will help.

Answering your questions:

A wider tire will cause a slow down on regular pavings.

A smaller tire will increase your speed, but will be less comfortable, especially when inflated hard.

Yes: because your cart has its own weight and you and your batteries as extra load. There is lug and wind,

All by all that scooter is IMHO build for endurance, sacrificing lots of speed. I am thinking (yes - for my next life) to build myself a solar car, actually a frame on good rolling wheels with only 4 times one 50 watts motor. Without gearboxes.

I will easily get 10 Mph, with a total weight of 150 Kgs.

I read some where, that some one made an air plane, that was Solar Powered...

That will raise the price of Fuel...

Most of the daily distances here are no more than 15 miles. Otherwise I end up in the Atlantic Ocean. I just feel bad about paying bills for evitables. (new word?) There is a solar airplane build in Zwitserland. it flew from Geneva to Brussels. You know when you start your journey, but never know when you can come back with it.

Evitables? I'm checking the Bible Dictionary, Couldn't find a definition any place else...

Nope... not there ether. Up to readers inturpitution... I'll read between the letters. make up my own difinition...

Well I found it in Egyptian Pyramid In syclopida: [ EVITABLES ] E = Down the stairs, or right side of primid. V = Trouth, River bottom. I= Piller ( Support) i= Light Candle. t = Sord stuck in ground (peace) T = Road ahead ends, Right or left only. A =Out side of Primid view. a = Snake escaping pit. B = Preginet Women. L= if you go back than up. E down stairs,or Right side of pirimed. S = Cobra Snake... ( what does that have to do with wheels?) Maby you better give it a difination.

You need to undrink the last three snorts of whatever.... (That post was plumb weird.)

Arrange it to turn double the rpm, at the same torque (if the motor will allow that).

Smaller Tires?

The general way to tune anything up is to remove excess weight and friction.
For an electric vehicle I'd say getting rid of resistive losses and making sure you have a top quality controller too.
When you say it needs a boost do you mean more torque or top end speed.
Del

Yes, Top Speed. Does about 5 m.p.h. I think it would still be safe @ 10 or 15 m.p.h.

I have an other Pride that won't run, I've been told the controller is broke. ( Very Expensive, " I'm still going to get it fixed!")

When Checking it out... I Connected th Battery To the Motor & the tires rolled. But No on /off switch ~ No Rheostat, for speed control.

Thanks for your reply.

These scooters have an electronic speed control. This device may limit speed. Does the unit have a high speed contactor that puts full battery voltage to motor. If it doesn't it's being limited by the control. Unless it is encapsulated there are pots on it that may increase output speed.

There were no listings for hp of this model. They do make others that go faster. Might want to check out the interchangeability of the motors and controller.

Thank You... I'm going to look into, the factory parts, & search after market, when I get an understanding, of the drive units.

If you up the voltage on the scooter you are going to fry the controller, which, as you know, is very expensive. Also, the power and control wiring is going to cook.

You are trying to spin gold out of hay here, and there isn't a tech solution that is cheap and easy. Switching the motor out to a 4 pole with higher rpm would give you twice the ground speed and get you to about 8 mph, which is about as fast as you can safely go with the tires and suspension on this scooter. This upgrade is going to cost you...a lot.

You can get a larger tire size for the rear end drive tires, but getting compatible rims to match the axle and bolt hole is going to be costly and difficult.

Mobility scooters, like these, for the most part are designed for use by folks with disabilities, both physical and cognitive, ergo, they have automatic braking, and that pesky controller that limits the speed and acceleration, but keeps the driver (and scooter!) safe. It is not possible for you to modify this, or any other similar mobility scooter, without compromising the safety features built in for you and the electrical system of the scooter.

Your best, and cheapest option in to venture away from the Medicare type scooters, and opt for personal electric scooters that don't have the restrictions built in.

ewheels is one of a handful of makers of scooters that would fit your needs, and no, I am not in that business, but I am in the business of the medicare type power mobility equipment, and I know you would spend less and get more getting something like I suggested. Good luck.

Found this....Evidently there are classes of these scooters, I believe you have a class 3, and you want a class 4 performance rate...The Pride Hurricane is claimed 9 mph top speed, Victory I think is 5mph...

You can't simply replace the motor with one that has greater H.P. and r.p.m.'s. The controller for his scooter is a PG Drive S-type controller rated at 70 amps. The motor you are suggesting would require their S-type controller rated at 120 amps. Also, the console board would need to be upgraded to a higher amperage, also the wiring harness, fuse and circuit breakers, and the transaxle mount assembly would need to be modified and upgraded.

Once you have spent about ....................$1,000.00 U.S. on these upgrades, and a whole bunch of man-hours, you will have bumped your speed up from 5 mph to about 8.5, but now you need to double the capacity of the batteries from the group U1, 36 ah batteries to group 22nf or 24nf, another $400-$600 and you've done nothing to stiffen the frame to accept the added weight and the ability to withstand the higher dynamics of driving at the greater speed.

This is not a practical, safe project for the uninitiated, and the money would be better spent on a purpose-built scooter for his needs, as I mentioned above.

Maybe he wants to build a sleeper...What's a couple a grand for the ride of your dreams?

Maybe the higher voltage will give you a higher RPM and enough Back-EMF to compensate or to keep the current and temperature under control. I wouldn't advise to allow the motor to "lug."

If you added the batteries in "parallel" and kept the same voltage, maybe you allowed it to "lug" down too slowly.

Check out sdelectricbike.com. Pat Winston has helped many people get their older bikes and scooters running better than new. Here's a photo of my "El Burro", twin Golden Motors Magic Pie with regen braking, Xtracycle longtail and twin 48V 15Ahr batteries good for 27 MPH and Minimum 40 mile range.

Have you tried connecting the motor directly to the batteries to bypass any governing that the controller might be doing?

If you want a scooter to go fast you need a fast scooter.

Scooter means different things in different places. This is my wife's scooter:

Well Bert, it seems you aren't the first person wanting a little bit more poke from your scooter.

Here's a 70MPH version
