I am converting an old computer fan into a blower.


Over here at 240 volts, its speed is not adequate.


Is there any way to increase the speed (rpm) without burning the
motor.

Thanks.

Steve.

Yes, increase the mains frequency and voltage(both).
Will the blower survive that? Improbable.
But for a short time, it will run faster.

In that case, get a blower ! A fan will not produce the back pressure
that a blower will.

Use two blowers.

The dumb answer is yes. Obstruct the airflow, it will spin faster.
