What is a permanent split capacitor motor?
That type of motor is called a permanent split capacitor (PSC) motor. The following is based on that assumption. Changing the capacitor value changes the amplitude and phase shift of the current in the auxiliary winding. Reducing the capacitor value lowers the torque values of the torque vs. speed curve as shown below.
How does reducing capacitor value affect torque vs speed curve?
Reducing the capacitor value lowers the torque values of the torque vs. speed curve as shown below. This method of speed control is often used for fans, because the torque requirement of a fan is lower at lower speed. That means that the fan load requirement curve crosses the motor torque capability curves only at one point.
Will a variable capacitor work on an induction motor?
It probably won't work (at least for a normal induction motor) and you certainly won't find a suitable variable capacitor. Is the motor an induction motor or brushed motor? Have a read through this similar question.
Can a centrifugal fan speed be reduced?
If you try to reduce the fan speed below the centrifugal switch's cut-in speed, you will get the effects complained of. I don't think that there is any easy answer here, short of changing the fan motor for one which is more amenable to speed control.
