No. You do not match cycles per second with PWM frequency. It should be much higher. You want enough height so that the motor runs smoothly (the motor’s inertia smooths the motion and the motor’s inductance helps cool the current), but not that the shunt losses are too high in your electronics to be excessive. Often at least 8-10 kHz, but you may want >20 kHz if audible noise is an issue. You have quite a bit of leeway before the frequency becomes completely “wrong”.
