If the voltage is lower, you need more field weakening to maintain a higher speed. The max speed of the motor is limited by voltage. Reduce the field weakening when the voltage lowers will just lower the rotational speed. Ironically even though you made a big point of of saying above what you...

You continue to say the torque sensor is the coil - “the torque sensor - in this instance - the fixed coil” - when it’s demonstrably true that the torque sensor is the hall sensor. The coil is just a transmission mechanism. I would code field weakening exactly as how it is done one of the...

The hall sensor has a magnet near it, and it is the movement in the magnet in relation to the hall sensor that senses the torque. The coils are an inductive method of transfer of this information allowing for crank rotation. Your original comment was that You stated the induction coil did the...

Hopefully will have one soon. Not quite sure how that is relevant to my comment though. Seems as though It’s not about grovelling for forgiveness. There were multiple points that you were completely wrong about, and most pointed towards someone with barely any understanding of how modern...

So that’s a DIY install motor? Must be if it’s the competition. Oh hang on… it’s not. Have you actually opened up a TDSZ2? Given you claimed it didn't have a cadence sensor and also your demonstrated complete lack of understanding around BLDC motor control, I wouldn’t be taking your comments...

Seems you care a lot about something you’ve said you are not buying.

That the manual from the open source firmware. Stock firmware doesn’t have these options.

You can, and it’s a documented feature. Look up the code for cadence mode in the OSF I linked. You can use this mode with a broken torque sensor and have power output calculated from cadence only. There is a cadence sensor built in to the controller of the TSDZ2. It is a physical hall sensor...

And further proof the TSDZ2 has a cadence sensor from these lines in one of the OSF codes. https://github.com/emmebrusa/TSDZ2-Smart-EBike-1/blob/master/src/controller/ebike_app.c Lines 1591 through 1626. See a few references to a cadence sensor there? That's an entire function called...

The TSDZ2 most certainly does have a cadence sensor. It's connected to GPIO_PIN_0 and GPIO_PIN_7. The cadence drive mode in some of the OSF's, and the derivation of required assistance power in the power mode (that uses torque multiplied with cadence to arrive at a value) require a cadence...

I understand what field weakening is, and how it is applied. But it doesn’t use any information from a cadence sensor, that as I said is sensing pedal cadence after a reduction drive and one way clutch. I’m very familiar with the TSDZ2 OSF code, and can happily point you to the relevant lines...

A cadence sensor, which measures the rate of rider pedal stroke, is definitely not used to determine optimal magnetic field strength. The two are not related at all. A BLDC motors optimal magnetic field angle in the stator winding is derived from the rotor position of the motor (so either hall...

What patents do you think would cover a motor driving reduction gearing driving a chainwheel? It’s hardly something new and novel that would be able to be patented.
