You won't be able to evaluate the 'current' setting unless the wheel is fully loaded. The reason you're seeing the wheel spin up to full speed with only a little throttle input is because at no-load, there's very little force to overcome.

Possibly a silly question, but is the controller switched on? Have you connected the ignition wire to battery positive? Assuming you do have the controller switched on, are you able to take a voltage reading between the red and black hall wires?

The controller doesn't know, but the sensor does. Inside a 3-wire dual hall PAS sensor is a pair of hall sensors spaced much closer together than the magnet spacing and some basic logic processing circuitry. This is used to calculate the direction of movement and limit the output to a single...

What happens when you connect the Sabvoton to your computer and run the hall angle test? Do you see any motor movement? Do you ever see an updated hall angle number?

Although a suitable alternative, that isn't the same connector the OP is searching for. As mentioned above, search for 'motorcycle connector' and you'll find what you need.

Are you able to post a photo of the connector, or a link to one?

What about using something like this to detect the chainring teeth: https://www.ebay.co.uk/itm/M18-8mm-DC-5V-NPN-NO-LJ18A3-8-Z-BX-5V-Inductive-Proximity-Sensor-Switch/113223650675?hash=item1a5ca7cd73:g:pFkAAOSwPPNbhRS3:rk:3:pf:0 It works on a 5V input and detects aluminium and iron from a...

Overlooking the issues of connecting your packs in series for one moment, I doubt that your Carrera battery would be able to sustain the continuous output required to reach the sort of speed increase you are talking about. What is the other battery pack that you own?

Yes, current increases during flux weakening in addition to the extra current required to reach those higher speeds. Field weakening definitely requires a stiff battery.

The beauty of field weakening is that efficiency is only affected whilst the magnetic flux is weakened. Below these speeds, the controller behaves as normal. Swapping the motor for a higher kV motor, or raising the system voltage would move the efficiency curve across the board.

I can personally recommend these, which I've been using for a number of years without any issues. They're currently priced £58.99, which makes them a bargain in my book...

FYI, this is the cheapest way to obtain a Phaserunner that I am currently aware of - £229.00 delivered, UK stock: https://electroncycles.co.uk/product/grin-phaserunner-electric-bike-field-oriented-waterproof-motor-controller-30v-90v-50a/

No, I haven't tried one myself, but I've only heard good things about them. My biggest issue with the Phaserunner is the 90A peak phase current limit, far lower than I tend to run nowadays. I'd consider one for use with my BBSHD FS build if the controller ever fails though. I've had my eye on...

A lesser version of 'field weakening' exists and is known as 'overspeed' or 'timing advance'. Similarly to field weakening, it provides a way to overcome the natural BEMF, but does so in a cruder manner and does not require an even more costly FOC (field oriented control) controller. The...

All the seller's listings have been deleted. I bet the account has been NARU'd!

There's no negative feedback yet because the listing is only 2 days and 7 hours old. Give it time. There's one positive feedback for the listing, obviously posted by a shill account.

I think you'll find 1 seller making off with £560 of ebay's money and 28 buyers claiming £20 back using ebay's buyer protection guarantee a more likely outcome. More fool ebay!

Yes, along with everything else the seller has listed. https://www.ebay.co.uk/sch/yang21130/m.html?_trksid=p3692

Hi. How long do you need it? Here's a 65cm version: https://s.click.aliexpress.com/e/GHCXATX Here's a 180cm version: https://s.click.aliexpress.com/e/TUlwCrn Dan

I'm not sure a gasket sealant will hold if the cap is cracked, but might be worth a try. Alternatively, how about dumping a load of epoxy over the cap to seal it? You won't be able to remove it after, but it should suffice until you replace the faulty brake.
