IMPSM Motor and Gearing

I have been planning to buy this Gearbox (see link below) for my E-scooter project, it has an option for a IMPSM (Internal Magnet Permanent Stator Motor) the D7500 (linked below), which I assume should work the same way as a BLDC motor with a Vesc, right? 

Also the follow up question, is there a way if you get a digital output or "custom" program to get different gearing ratios into the Vesc, in this case, reversing motor direction changes gearing apparently from  1:4.95 to 1:1.95, haven't yet done any custom programming in Vesc, was thinking of when reversing change gearing ratio and assume it's still a "positive" speed i.e. moving forward.

If anyone has input, done it before or has experience it would be much appreciated !

That is a very specific use case and it would need custom programming by someone with the skills to do that. Maybe it can be scripted in the lated VESC-Tool.

The VESC should work fine with IPM motors. There is even MTPA and field weakening support in the latest firmware.

Hi, i have custom built an IPMSM and when am trying to run it using VESC. The R, L detection runs fine. But am having troubles detecting flux linkage. Can anyone throw some light on this
