"WebA higher frequency will cause a shorter cycle time of the PWM; hence the current will have less time to rise. Portescap recommends using PWM frequencies not less than 50 kHz for brushless DC motors. PWM frequencies of 80 kHz or more would be even more appropriate for motors having very small electrical time constant. " - Bldc pwm on pwm

You'd expect rpm to do likewise, but the TS is reporting the rpm decreases as the frequency increases. The problem may be that the circuit is missing pulses as the frequency increases beyond the fixed pulse-width.
