The concept of motor speed, measured in revolutions per minute (RPM), is influenced by the number of poles a motor has. Typically, as the number of poles decreases, the speed of the motor increases. A double-pole motor would operate at a lower speed than a single-pole motor due to the increased number of magnetic poles in the motor's stator, which need to be energized to create a magnetic field.

In this scenario, referring to a double motor, it would tend to operate at a speed that might seem faster than a single but still slower than others mentioned, like a triple or quadruple motor. However, when we consider RPM in terms of design and standard configurations, a motor with double configurations tends to have better performance due to its ability to balance speed and torque well when compared with motors featuring a higher number of poles.

Through understanding the relationship between pole count and speed, we can see that a double motor configuration provides an advantage when balancing those two factors efficiently, thus allowing for higher speeds without sacrificing performance in many applications.
