What is the maximum RPM supported by sine-wave driver ICs?

The maximum RPM is determined by the motor and its input voltage. Considering the effective range of sine-wave PWM drive, roughly 1/100th of the PWM frequency is considered to be the limit of RPM.
For example, assume that the PWM frequency is 16 kHz and that the electrical angular frequency is 160 Hz. Then, for a four-pole motor, 4800 rpm is considered to be the limit of sine-wave PWM drive.
