Welcome, electrospinner.

Here is a diagram showing how to connect the various bits.


The "servo tester" in the diagram is the Manual Servo Adjuster linked by Jim above.

The "ESC" is a brushless Electronic Speed Controller suitable for your motor.

The "battery" could instead be a power supply.

A possible challenge with the motor you have selected is its kV of 1500, so it wants to spin rather fast. It might be difficult to easily control the low end of your desired RPM range. A motor with a lower kV would be easier to operate at the relatively low RPM you are targeting.
