**RPM per Volt**
The term “RPM per Volt” refers to the measurement of how many revolutions per minute (RPM) a motor shaft completes for each volt of electrical input. It is a key parameter used to evaluate the efficiency and performance of electric motors, especially in applications like RC vehicles, drones, and robotics. Understanding RPM per Volt helps in selecting the right motor for your project by providing insight into the motor’s speed characteristics relative to the supplied voltage. Higher RPM per Volt values typically indicate motors that spin faster under given voltage conditions.
