What's the difference?

[HighNear90]

What do y'all think is the difference in the motors and controllers in these 2 kits:

48v 500W

48v 1000W

Thanks in advance for any input

Likely the exact same motor & accessories.
The 1000w version runs a 20amp controller
500w runs a 10amp controller.


*Upon further reflection*
Could be the same controller, 500w run with a limiter.
Less likely but still a possibility is solder'd shunt on the 1000w version.
Long&short, 1000w Kit offers, well, 1000w.
500w, 500w. :lol:

Get The 1000w, trust me.

*1 mo' thing*
Take a look @ the pics. YesComUsa uses.
They continue to advertise that rusty ass freewheel.
I mean come on

They may look the same, but they are far from the same motor. And they don't come with the same controller either. I've bought both kits and a front kit also. The controller with the 500W motor is a basic 12 fet controller. The controller that comes with the 1000W motor is a 15fet controller and the one I got had extra features that could be enabled. regen braking, cruise control, 4 speeds,etc. Both controllers were 30A Using either controller on the 1000W motor produced more power and speed. The motors are GM motors, HBS48-500W and HBS48-1000W. I think they are shipping newer controllers now, but I got an Infinion based EB-215 with my 1000W and only a 5 gear freewheel with all of mine. . The annoying thing is none of mine came with rim tape and all came with a 1.75" tire. After the first, I replaced the tire and tube before installing and installed rim tape at that time. I'll let the fact that I've bought 3 of them and would buy from them again speak for itself. The little SLA chargers that come with them are cheap crap, as are most, but most people hopefully won't be using SLA anyway. I'd also recommend getting the 1000W kit. It's worth the extra money.

Thanks y'all for the replies. I'll definitely get the 1000w kit.

Sure looks like the same motor to me. Controllers would be different for sure, even if they looked alike.

Looks can be deceiving. The 1000W motor weighs more, for obvious reasons. More copper, bigger magnets.the 500W motor is rated for 380rpm@48v, while the 1000W motor is rated for 470rpm@48v. Using same controller and battery pack the 1000W motor has more torque and a higher top end. Yes, I have both models.

Are you sure it's heavier, and any different?

All motors i've seen that do this advertising are basically a different wind.
The 'xxx watts' is actually what it will draw at cruise ( rounded to a nice even 250w increment ) when you apply 48v to it.
A faster wind will draw more watts since it will go at a higher speed.

Just thought i'd throw that out there since this seems to be the rule and these motors would be the only exception i've seen.
There is usually a difference in front motor vs rear motor, but not rear vs. rear.

I'd have to have both motors on that bench in my garage for me to believe there was any difference, except for possibly different windings for different rim sizes.

I could be wrong though, after all, who knows what they send you exactly. Many other vendor ebay ads show pics of 3-4 different motors. Could be the 500w is a little gearmotor and the 1000w is a big dd motor, and both ads just show the dd type.

I wonder why they never quite made the ES recomended vendor list?

Definitely a bargian though, free shipping to USA. Isn't the motor a golden motor type, clone or whatever?

No difference... they're both cheap... lol

Yeah, I know. My main bike is an HS3540, but I'm building a bike for a buddy to keep at his hunting camp for getting to and from his treestand.

Also, Google Chrome thinks your site "eco-wheelz.com" has malware. I got a red warning screen when trying to look at kits. Call your webmaster ASAP.

Well, I didn't actually weigh each, although the specs say the 1000W weighs more than the 500W. About 1-2kg iirc. And yes, their side by side performance proves they are different. As does the amount of manual peddling without power. The 500W isn't very noticeable at all. The 1000W is. There's also the fact that the wires coming out of the motor are a lot bigger on the 1000W motor. Also, the 500W motor is rated fro 380rpm@48V and the 1000W motor is rated for 470rpm@48V.
Performance test consisted of using the same 14s lipo battery pack and and swapping the controllers between the two motors. With either controller, both motors performed the same. The 1000W motor had consistent more torque and top end compared the the 500W motor. The 1000W motor was about 7-8 mph faster and got to max speed faster. Both controllers were 48V 30A. One was a 12fet. The other was a 15fet. There's no other logical explanation other than the motors are NOT the same motor.

The 'xxx watts' is not what you think it is. Watt ratings are the max continuous duty cycle ratings for a motor. The higher the rating, the more watts you can put into it before it burns up.

Also, if you change a motors windings then it's obviously no longer the same motor. And depending on the size of wire used it watt rating may also change.

The simple fact is that they are not the same motor.

 

[dogman dan]

Sounds like you are the guy who knows. They are different windings and different phase wire guage.

There are lots of hubmotor manufacturers that just sell the 1000w dd motor. But sell it with different controllers of various wattages. So in those cases everybody gets the same durability and winding speed.

I just haven't been interested in Yes-motors. I'm buried in nice 9c ones.
