Performance specificaions
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.
