Is A 24v 500w & a 48v 1000w The Same on the Same Voltage?

[DAND214]

What determine the power of a hub motor? I have a 24v 500w rear hub and a 36v 500w also. I was asking if the 48v 1000w motor would run the same as the 24v 500w on the same voltage, say the 24 v run on 24v and the 48v on also 24v, what will be the results? Then the 24v & the 48v run on 36 and then on 48 volts. The reason I ask is I am running a Golden 24v on 48 and a conhis on the same and the run about 30mph no pedaling and 33 pedaling. I don't have a 48v 1000w hub but wonder what it would do on 48v. The 24v hub on 24 is about 18, on 36 it's hitting 25 and 48 30, so what happens if you get a 48v 1000w will it be the same? I know your going to tell me the 24v is running too hot and that s not true, I can ride for 2 hours at almost 23 mph and the hub is warm, controler cold(12 fet 4110 infinion shunt half soldered). I like the tourque they have but wonder if the !000w hub would be much differant.
Also my 9C on 48v is just short of 28 no assist. So will a 100w hub make a big change.

It would just depend on the motor. Most of the direct drive brushless motors are essentially the same motor whether they are a 250 watt version or a 1000 watt version.

The difference is mostly the controller voltage and amps. There may be smaller guage phase wires into the smaller wattage ones though, so the power wiring might need an upgrade to go to 48v and run for long periods of time.

Other motors may be different. I fried a brushed hienzmann motor in about 30 minuites use by taking it from 400 watts to 1000. That one did get hot faster than I thought possible.
