Re: DD Hub motors: Why only 23 pole pairs?

Hi fetcher and John in CR: Thanks for your replies. I understand that a given DD hub motor in a smaller wheel is effectively "geared down", and runs more efficiently at lower speed. In my data this is reflected in the total watt-hour figure: 867 wh declining to 815 wh to move the bike around the loo...

DD Hub motors: Why only 23 pole pairs?

Over the last couple of years I have been experimenting with direct-drive (DD) hub motors on my bikes, building them into ISO 559 wheels (26" MTB wheels). Since I live in an area where there are many hills, I have found the advent of Statorade, Hubsinks, and motor braking to be beneficial. My recent...

Re: Ebike Hub Motor overheating cooling solution - HUBSINK OFFICIAL THREAD

Hi Robert: West Coast Electric Cycles will soon have in stock a 45mm stator DD hub motor. https://westcoastelectrics.com/product/45mm-ddhub/ This one may be your best option, although I still doubt it will get you up your hill without your pedaling at least a little bit. I recommend the "4T" option....

Re: Ebike Hub Motor overheating cooling solution - HUBSINK OFFICIAL THREAD

Hi Robert: I'll assume you've tuned the Phaserunner for your motor. If you're seeing 66C at the controller and the motor is overheating, that's a sure sign that you're running the motor into the "heater zone", where too much power is being converted into heat. You might be better served by a slower ...

Re: Ebike Hub Motor overheating cooling solution - HUBSINK OFFICIAL THREAD

Hi Robert: What controller are you using to drive your motor? Is there a chance that the controller is not tuned well to the motor? Does the controller get hot to the touch? The controller should seldom get more than detectably warm to the touch. Your speeds are similar to mine, but your power is 50...

Re: Ebike Hub Motor overheating cooling solution - HUBSINK OFFICIAL THREAD

Hi Robert: Yes, your 20" wheel is an ISO 406 wheel. There are different nominal 20" wheel sizes, ISO 406 and ISO 451 being the most common. These are both considered 20" wheels. While the 451 rim is larger, the tires to fit that rim are smaller. The 406 rim is smaller, but the available tires are us...

Re: Ebike Hub Motor overheating cooling solution - HUBSINK OFFICIAL THREAD

Hi Robert: SlowCo's recommendation to remove 1 spoke is how I got my Hubsinks onto my 406 wheel. You should be aware that if you install Hubsinks on a 406 wheel you will probably need a 90-degree pump-head adapter of the kind used to inflate tires on disk wheels as most standard pump heads will not ...

Re: Definitive Tests on the Heating and Cooling of Hub Motors

I recently built a 406 wheel around an Edge1500 motor (35mm stator). I started with about 4.5 mL of FF, but I found that the rolling resistance felt significantly greater than with the same amount of FF in a motor build into a 559 wheel. The rolling resistance was also noticeable as reduced measured...

Re: Compact Field Oriented Controller, ASI + Grin, limited r

What can I do to prevent damage but still have some regeneration? Easy, just set your charger to only charge to like 90 or 95% and then you'll always have plenty of room for regen energy even at the start of a trip. Otherwise I would set the Phaserunner's max regen foldback voltage to 4.25 V/cell, ...

As most have discovered the ...

Re: Cycle Analyst V3 preview and first beta release

Normally we would suggest a small cap on an analog signal line to smooth or bypass noise. The problem in this case is that the line has the digital buttons riding the same signal and the firmware that discriminates analog voltages and digital button pushes is sensitive to the digital button ON/OFF/...

Re: Cycle Analyst V3 preview and first beta release

I do have the odd sensation that if I pedal while engine braking [at a set speed], I can feel the motor attempt to compensate for the slight variation of speed with each pedal stroke in syncopation with my pedaling. I stand by the above quote, but I also notice a similar problem when merely soft-pe...
