Product Description

40AX2 Dual Way Bidirectional Brushed Speed Controller ESC 54x48mm Mixed Control 7v-25v for Metal Track Tank/Dual Motor Ship

Specifications:

Adapted voltage 7v-25v

Can use 795 775 540 550 380 390 high current motor

Current: single forward 40A, reverse 40A

How to identify the forward and reverse direction 1) The throttle channel of the receiver is changed to the steering gear. When pushing the oil, the steering gear rotates counterclockwise when viewed from top to bottom. 2) Also use our shop's PWM tester to plug in the receiver for testing, and the increase in the fuel value is positive)

The midpoint of the remote controller is fixed at PWM 1500us (+50 -50), and the run is automatically adjusted from 900-1100 and 1900-2100.

Start with the midpoint (one beep at power-on, and two beeps at midpoint 1500, ESC will start)

With out-of-control protection (lost signal (in the accident, the signal line was disconnected)), for safety and motor protection, you need to return the throttle to the center and unlock again

Power-down 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, motor stops after protection, and battery voltage recovers after motor stops Back to the midpoint, you hear the motor unlock again)

bec output 5v max 3A to meet your needs for receiving and steering gear power supply

Overheating protection (overheating 90 degrees, the ESC stops output, and recovers after cooling down)

Note:

1) The left and right motor wires marked in the picture (easy to distinguish), the motor must not be confused, otherwise the ESC may burn in seconds

2) Overheating protection takes effect only when both circuits are used. Otherwise, it is difficult to take effect if only the single circuit is used to regulate the uneven heating and cooling.

3) Motor +-In addition to the C104 anti-interference capacitor, other capacitors cannot be connected (for example: 2uf or more capacitors)

4) Some ESC motors with a current less than 2A cannot use this ESC, because small-winding motors with dense windings will interfere with the potential after the motor rotates, and the throttle will stop at more than 90%. (Please select 2A or 5A ESC for geared motors with current less than 2A)

Board size: 54x48mm weight 56g (including wire, heat sink)

with 16awg silicone motor wire, 18cm in length

For use in a closed environment, you can retrofit and install heat sinks, or seal the entire board in thermally conductive silicone grease, which is waterproof and dissipative.

Key points of mixed control debugging:

First make sure the forward and backward motors are in the same direction. (If a motor is turning incorrectly, exchange the +-stage wires behind the motor)

Then adjust the direction, if it is not as expected, the remote control may be reversed, set it back

ESCs directly source components from brand manufacturers, double copper thickness

The dual-mix ESC has the following modes

Mixed control mode (both throttle / steering mode): 2 or 3 channels (2 channels are recommended because 2 channels automatically return to center) to control the throttle, 1 channel (or 4 channels) to control speed difference steering, throttle ratio 100%, steering ratio 100%, steering priority. Suitable for: tank (in this mode, gun control can play tanks), 4-wheel drive trolley (apm can be installed)

Two-way independent: it is equivalent to two independent ESCs (if you want to simulate a real tank, the white three wires on the input end are connected to the receiver throttle (3 channels), and the yellow single wire is connected to the receiver 2 channels; but in fact Henglong ’s Tank is also Mixed control mode, because better operation)

Two-way synchronization: In mixed control mode, do not connect a single yellow wire, so that the two-way motor output is consistent.

As shown below, there is a J1 solder joint on the right side of the back of the board. After welding, it is a dual independent mode (while indep is printed next to the solder joint, that is, independent).

1x 40Ax2 ESC
