About aircraft model motor
Current model power's basic configuration is "brushless motor" plus
ESC combination of programs, most of whom we call such a motor as a
"brushless motor", some people call it the BLDCM.
First of all, it is called DC brushless motor is a certain problem,
the data show that the square wave-driven BLDCM back-EMF is similar
to the trapezoidal wave, trapezoidal back-EMF is not accidental
formation, but artificial control, mainly used Whole concentrated
winding, the shape of the permanent magnet tile, multi-radial
magnetization and so on. This type of motor is suitable for square
wave control, which is commonly used model aircraft control mode.
The motor has the following key words: the outer rotorfractional
slot, concentrated winding,
permanent magnet synchronous motor.
Brushless motor parameters and characteristics
We choose a brushless motor, you will see a lot of similar named
models, such as 2216,2814, the figure, the first two is the stator
diameter (mm), the latter two are the stator height (mm). The more
the outer diameter and height of the stator, the larger the iron
core of the stator, the more the number of turns of the coil is
wound, and the greater the power of the motor is. Of course, the
bigger the size, the bigger the power, but the bigger the weight.
If a motor is 2216, said the stator diameter is 22mm, the stator
height is 16mm. The outside diameter of the stator and the height
of the stator are proportional to the power of the motor. The
height of the stator of the 2218 motor is higher than that of the
2212 motor, and certainly the power is also large. The significance
of this size is to look at the model can compare the size of the
two motors, but this is generally only the same stator diameter and
height are not the same, or the same height and outside diameter is
not the same, the stator diameter and height are different
Difficult to compare this model.
It should be noted that this size refers to the stator, not
referring to the motor size, the thickness of the motor shell,
cooling bad, the base height affect the motor size, so use the
stator size to determine the power than with the appearance Size to
standard and fly.
2.Motor slot number and pole number
1) Number of slots (N): Number of slots in the stator core. Brushless motors are three-phase motors, so the
slot number is a multiple of three.
2) the number of poles (P): the number of magnets on the stator,
the magnet must be paired with the North and South poles, the
number of poles must be even.
Motor slot number and pole number Some models of the motor directly
write the number of slots N pole P, such as 12P14N, is 12 slots 14
3) Slot number and pole number characteristics
a, the number of slots (N) and the number of poles (P) are
inversely proportional to the higher maximum speed, that is, the
smaller the number of slots (poles), the higher the best speed of
the motor. Such as 9N12P highest speed than 12N14 high.
b, in the case of the same number of slots (N), the number of poles
(P) is proportional to the torque, the greater the number of poles,
the greater the torque.
c, under normal circumstances, the greater the number of slots (N)
and the number of poles (P), the smaller the motor frustration
(when the motor is not charged, hand motor rotation, will feel the
feeling of a card a card frustration), theory Vibration on the
motor will be less, but because it is difficult to balance the
number of slots.
The brushless motor KV value is defined as speed / V, which means
an increase of 1 volt (V) to the input voltage, an increased speed
of the brushless motor at idle speed (rpm). From this definition,
the voltage and the motor idling speed follow a strictly linear
proportional relationship and are constant regardless of the
motor's compliance with that operating voltage, voltage and speed.
1) Calculation of idle speed
Remember, this value refers to the motor idling without propeller
and other load speed under the relationship between the voltage,
such as KV is 650, at 11.1V voltage idle speed is 11.1 × 650 = 7215
rev / min, KV value is 900, the same The idle speed at voltage is
2) The relative value of the KV value of the relative comparison
(only the same stator diameter and stator height of the same model,
different KV value is not much meaning, such as a certain brand of
2216 motor, 650KV, 800KV, 900KV three models )
High KV Low KV
Stator coil winding turns less
The maximum output current is small
The same voltage torque small big
Under the same voltage speed level
Matching propeller diameter small
3) can not compare the motor by KV is good or bad, can not say
KV380 better than KV600, the same model with different KV value of
the motor price is the same.
4. the outer rotor and inner rotor
Brushless motor according to the location of the stator can be
divided into two kinds of outer rotor and inner rotor.
1) Outer rotor: The stator is inside, and the rotor is called
The figure is a typical external rotor motor, the rotor is
surrounded by a stator, the rotor and the shell together, when
rotated, the shell (excluding the base) and the output shaft
together. Internal rotor torque is relatively large, KV value is
2) Inner rotor
In contrast to the outer rotor, the inner rotor is the stator
wrapped rotor, rotating, just the rotor rotation (shell does not
turn). Inner rotor torque is relatively small, KV value is high.
