You will need a pair of step pulleys to have adjustable speeds. There is no work around for just one. Order 2 if you are going to use a 3 step pulley system.
Basically, you mount one to your motor, the other to the drive shaft. When the motor is stopped, you manually move the belt from one set of grooves to the next to get 3 different speeds. A poor man's multi-speed controller.
