Introduction
A generic motor controller kit is show below.
ST’s STM32 offers the performance of the industry-standard Cortex®-M core at the service of vector (or field-oriented) control (FOC) algorithms, widely used in high-performance drives.
The STM32 PMSM FOC SDK(STSW-STM32100), which includes the PMSM FOC FW library and ST MC Workbench, allows the user to evaluate the STM32 performance in applications driving single or dual Field Oriented Control of 3-phase Permanent Magnet motors (PMSM, BLDC).
STM32 PMSM FOC SDK is part of ST's motor control ecosystem which offers a wide range of hardware and software solutions for motor control applications.
ST MC Workbench is a PC software which reduces the design effort and time in the STM32 PMSM FOC firmware library configuration.
The user, through a graphical user interface (GUI), generates all parameter header files which configure the library according to the application needs and can in real time monitor and change some variables of the algorithm.

How to convert RPM to the Frequency of the sinusoidal current that must be generated for each phase, considering the number of pole pairs.
Suppose to have a 3 phase motor. 
Suppose to have 20000 rpm, this means 20000 laps (mechanical) per minute.
And suppose that the motor is a 4 pole pairs.
The formula for calculate the mechanical frequency (MF) is:
MF = rpm/60
20000 rpm ==> laps (mechanical) per minute ==> 20000/60 = 333.33 per second (mechanical frequency)
To calculate the electrical frequency (Hz) is necessary multiplied the mechanical frequency by the number of pole pairs.
Hz = MF x Number_of_Pole
333.33 x 4 = 1333.33 Hz
This is the frequency of the sinusoid of current that must be generated for each phase.
But...
The sinusoid must be (Nyquist) at least twice but as we know it is not enough... we say that takes at least 10-12 times, (most bigger is, the better is) to get an accurate reconstruction of the curve... the PWM frequency is our sampling frequency (in the case in which the vector control is done every period of PWM).
So the PWM frequency is:
Fpwm >= 1333.33 * 12 = 16 KHz
Consider that 16 KHz is the minimum conditions.
If it is possible the suggestion is: go up in frequency but take care the switching losses.
Suppose to have 20000 rpm, this means 20000 laps (mechanical) per minute.
And suppose that the motor is a 4 pole pairs.
