Professional terms in brushless motors:
Rated voltage: refers to the working voltage suitable for brushless motors. Brushless motors are suitable for a wide range of operating voltages, and the rated voltage is determined by specifying the load conditions. For example, a 2212-850KV motor is assigned a load of 1045 propellers, and its rated working voltage is 11V. If the load is reduced, such as with a 7040 propeller, then this motor can fully operate at a voltage of 22V. However, this working voltage is not infinitely rising, mainly subject to the highest frequency supported by the electronic controller. So, rated work is determined by the working environment.
KV value: Brushed DC motors are marked with rated speed based on the rated working voltage. Brushless motors introduce the concept of KV value, allowing users to intuitively know the specific speed of brushless motors under specific working voltage. Actual speed=KV value * working voltage, which is the actual meaning of KV, which is the speed per minute under 1V working voltage. The speed of a brushless DC motor is directly proportional to the voltage, and the speed of the motor will increase linearly with the increase of voltage. For example, the speed of 2212-850KV motor at 10V voltage is 850 * 10=8500RPM (RPM, Revolutions per minute).
Torque: The driving torque generated by the rotor in a motor that can be used to drive mechanical loads.
Speed: The speed of the motor per minute, usually expressed in RPM.
Maximum current: The maximum current that the motor can withstand and operate safely.
Maximum power: The maximum power that the motor can withstand and operate safely. Power=voltage * current
The relationship between voltage and efficiency of brushless motors:
1. Power=voltage * current
2. Calorific value=square of current * resistance
Two conclusions can be drawn from the formula: under the same power, the higher the voltage, the smaller the current, and it can be inferred that under the same power, the higher the voltage, the smaller the heat generation.
Conclusion: The higher the voltage used in the same aircraft, the smaller the current and the less heat generated, resulting in higher efficiency.
