The motor is an Electrocraft RPX52600V12. The datasheet indicates 14 poles, 12V, 20.5A, .6 Nm, 1 Ohm, and .6mH. It is 'Y' connected. There is no access to the common center connection. I don't know if it has concentrated or distributed windings. Measuring phase to phase when turned with a drill it produces an absolutely perfect sinusoidal waveform on an oscilloscope.
Q1: Does this mean it is constructed as if it were a PMSM with sinusoidal BEMF rather than a BLDC Motor with trapezoidal BEMF?
After reading the stack exchange topic under 1 I am still uncertain about the answer to the above question because
Rotating the shaft it cogs 24 times. One post I found here said:
"The # of cogs per revolution is equal to the least common multiple of the number of poles and the number of stator slots"
The least common denominator for 14 poles and 24 cogs is 1, an impractical number of slots.
Q2: Is it possible to know the number of stator slots?
