Motor Profiler for motor with Non-Sinusoidal Back emf

[STuser2]

I bought a motor as a first step i want to run the motor profiler, the specifications of the motor are

48V, Output: 500W, Rated Current: 16A, Rated speed: 600 RPM it is a geared motor with ratio of 1:6 and the number of pole pairs is 4.

I got confirmation before purchase that the back emf will be sinusoidal, but when i have done hand rotation and verified the waveform between the phases i get the below waveform

So, request to please confirm if the motor profiler can be run with the above back emf? If not i have to exchange the motor. This motor is only for validating the profiler and hall sensor placement angle and understand how to change the profiler parameters before i move to the actual motor.

One other question is in the window for current in profiler, i am entering 16A * sqrt(2) = 31 amps is it correct?

i have run the profiler it runs for few cycles and ends up with speed feedback fault the phase currents during the time the motor is running are sinusoidal

Yes profiling did work
