20Ax2 speed difference ship 2S-4S two-way unidirectional brushed ESC nesting ship with mixing control
parameter:
2S-4S dual unidirectional brushed ESC
20Ax2 speed difference ship
Nesting boat comes with mixed control overheating protection,
Note: Both ESCs are unidirectional, which means that they can only move forward, not backward.
The motor can only rotate in the forward direction and not in the reverse direction. Please confirm whether it is suitable for use before purchase.
This ESC is designed for speed difference boats, nesting boats, etc. using 380, 550, 775 motors.
Parameters: 6-16v available 2-4s single 20A (electrically call 240A MOS tube, the peak is far more than 20A)
* Remote control signal pwm (1000-2000)) (1100-1900) Automatic adaptation of run length
* Low-throttle start prevents unsafe operation of high-throttle motors. (Start below PWM 1150)
(Note that some throttle controls are reversed, such as Ledi, and some commented that the throttle must be adjusted by 90% to unlock, it is his throttle reversed)
* With start-up sound (The sound is caused by high-frequency current vibration motors. Due to the different motors, the sound size varies; small motors may be slightly rotated by the current, do not be surprised)
* With runaway protection (lost signal (here the ESC signal cable is broken), motor stops)
* With overheating protection (above 90 degrees, the ESC stops output, and resumes output after cooling; please use dual circuits at the same time (only one channel, the ESC is unevenly heated, overheating protection may not take effect)
* Power failure protection: power supply voltage is lower than 4V, ESC restart protection (such as: high current discharge, poor performance battery voltage drop is too large, ESC protection, the motor stops after protection, and the battery voltage recovers after the motor stops , Back to the midpoint, you hear the motor unlock again)
* bec output 5v max 3A
* The bottom plate already has heat sinks. After the test, the 4S 775 (about 10,000 rpm) in the shipyard was full of oil for 2 minutes, and it did not trigger overheating protection. Gift of external heat sink to enhance heat dissipation (volume will become larger)
Size: 42x33mm Weight: 34g (including wire) Motor wire 18awg 20cm long
note:
The power switch on the ESC is temporarily turned off. That is to say, even if it is turned off, the ESC still consumes microcurrent, and it is not necessary to unplug the power battery for a long time.
(If you do n’t want a small switch, just cut off the connection of the small switch and it will be available after power on)
The ESC is not waterproof, you have to do it yourself
The paddle should be protected in the cage at all times to ensure absolute safety.
There are 2 modes
1. Speed ​​difference control mode (default)
Mixing control = Throttle X 100% + Direction X 100% (This ratio is determined through multiple tests and feedback from the model friend)
If you open the 50% throttle, and the direction is to the left, the left motor will decrease by 50% and the right motor will increase by 50%. As a result, the left motor will stop (ie, the throttle is 50%-direction 50% = 0). , Full turn on the right (ie throttle 50% + direction 50% = 0)
If you open the 100% throttle, and the direction to the left is farthest, the left motor will decrease by 50% and the right motor will increase by 50%. The result is that the left motor turns 50% %), 100% full rotation on the right side (throttle 100 + direction 50% = 150%, but the maximum motor output is 100%)
Two-way synchronization (a special case of mixed control mode)
The single yellow line is not plugged in (equivalent to invalidating the differential signal). The output of the two motors is consistent, which is suitable for a rudder aircraft with dual thrust.
2. Two-way independence
Is equivalent to two independent ESCs
Signal from 3-wire port to control the motor near the battery line
1-port signal to control another motor
