That one has an ancient Nagaoka MP10 from the 80s. Was on my Revolver. Really smoking deal cart.
They never need trapezoidal, that's just the easiest way to drive them. Some motors are carefully engineered for low cogging forces, typically with sinusoidal drive (and will thus be more coggy with trapezoidal) - 3-phase AC servo motors and BDLC's are basically the same, but optimized a bit differently.
Until you change to slotless motors there will always be noticable cogging due to the reluctance changing with position. That's why Maxon motors are a good choice as they are slotless designs - but you pay extra for that.
I have had good success with the Anaheim motor for no coggimg. Which maxxon BLDC do you recommend?
I looked at the Flat series. Tried to find one that ran within the parameters I am looking for to drive it easily with a Sinusoidal or SpaceVector waveform. (Aka greater than 5ohm line resistance)

For Maxon its more a case of what you can afford(!) - obviously your choice is much more limited second-hand, but you should have some idea of what you need in tersm of power and torque and voltage.
