Brushless motors have a wide speed range, from a minimum of 3,000 rpm to a maximum of 100,000 rpm. This wide speed range makes brushless motors suitable for a variety of applications. The speed of a brushless motor is mainly affected by several factors:
Design and specifications: The design and specifications of a brushless motor determine its basic speed range. For example, some custom brushless DC motors can be designed to have higher rotational speeds.
Voltage: Voltage is another important factor in brushless motor speed. According to the search results, the speed of a brushless motor is directly proportional to the voltage, which means that increasing the voltage can significantly increase the motor speed. For example, an 850KV brushless motor can reach 7260RPM (revolutions per minute) at 8.4V voltage.
Application requirements: The final speed of a brushless motor also depends on its specific application requirements. For example, high-speed brushless motors may be used in specific equipment that require extremely high rotational speeds.
