As you decrease speed on a 2 pole motor, you also decrease the torque. So in the critical lower speeds you have the least amount of power and a greater chance of belt lag. For this reason, we feel the full torque in the lower rpm range is the most important consideration and a 4 pole 1800 RPM motor is a win win given the options!

AC Motor Speed Controller Circuit - ElectroSchematics.com

This triac-based 220V AC motor speed controller circuit is designed for controlling the speed of small motors like drill machines. The speed of the motor can be controlled by changing the setting of P1. The setting of P1 determines the phase of the trigger pulse that fires the triac.
