3ax4 6-25v 4 Way 3a Dual Mode Bidirectional Brushed Esc Electric Speed Controller Support For Mecanum 4-wheeler Car Models – Parts & Accs

Features:

     ①battery：2 – 4S ( 6V – 16.8V )lithium battery can be used (power supply + -reverse connection is prohibited).

②Single track 15A (3 ways 15Ax3)

③ Silent design, eliminate annoying driving noise, which is especially noticeable when the motor does not rotate or at low speed

④ The central point of the remote control is fixed PWM 1500us (+50 -50), the minimum run range is 700-1100 and the maximum is 1900-2300 automatically adapting, and the excess is ignored.

⑤ Power-on prompt (you will hear a "beep" of the motor, indicating power-on)

⑥ Start with the middle point (the throttle channel is about 1500, you will hear the motor lift and tone prompt to start)

⑦ With runaway protection (loss of signal (in an accident, the signal line is broken), for safety and motor protection, the throttle needs to be returned to the center and unlocked again.

⑧ With neutral brake (with solder joints on the back, the neutral brake can be removed)

⑨ The ESC has a certain degree of over-current and overheating protection (for example, when the rated current exceeds the rated current, the output of the overheated motor will stop, but if you suddenly connect a motor with a larger than rated current, it will also burn out)

⑩ BEC output (red and black in 3P white, red and black lines) 5V 1A to meet your needs for receiving power, the voltage regulator comes with overheat protection (Note: Additional power supply is prohibited on the receiver. If you want to supply additional power (such as connecting a flight controller with BEC or other ESCs), please cut off the red wire in the 3P white, red and black wires of this ESC)

 

ESC Modes:

⑴ 1-way and 2-way mixing mode (throttle/steering mode) (default): 2 or 3 channels (2 channels are recommended, because 2 channels automatically return to the center) control the throttle, 1 channel (or 4 channels) control the speed difference steering, throttle steering. The ratio of the channel is 100%, the throttle priority. 

⑵ Independent mode: 1, 2, 3 channels are independently controlled, and the motor output is 100% when the throttle is 100%. Equivalent to three independent ESCs

⑶ Two-way synchronization: In the mixed control mode, do not insert a single yellow wire, so that the output of the 1-way and 2-way motors is the same

 

Key Points of Mixing Control Debugging:

⑴ (The 3P white wire is plugged into the accelerator, and the single yellow wire is not plugged in) Make sure that the forward and backward motors are in the same direction. (If a motor is turning the wrong way, swap the + – stage wires on the back of the motor)

⑵ (plug in the single yellow wire again) to control the direction, if it is inconsistent with the expectation, exchange two motors (you can also set the direction channel forward and reverse)

⑶ Note: 1) The small power switch acts on the BEC, so it switches the receiver power supply at the same time. 2) Even if the switch is turned off, the ESC still consumes micro-current, and it is not necessary to unplug the battery for a long time

 

Inconsistencies Regarding the Speed of the Dual Motors:

⑴ As long as the steering is in the neutral position (PWM 1500us), the dual outputs of the ESC are consistent, because the single-chip microcomputer can control the duty cycle very accurately. You can leave the single yellow wire unplugged (equivalent to disable the steering, at this time it is a dual-channel synchronous mode), if the output is still inconsistent, it may be that the motor, gearbox or crawler are inconsistent, which can be alleviated with steering fine-tuning

 

Turn off the Control but the Motor will Turn:

① Because you turn off the control, the receiver will output a low throttle signal. Low throttle is reverse for the ESC, and full speed reverse. After the control is turned off, the receiver will automatically output a low throttle signal, also called runaway protection

② Solve methods: 1) The throttle is connected to 2 channels, and the 2 channel runaway protection is generally 1500 in the neutral position (if not, please set it), which means stop. 2) According to the standard process, first turn off the power of the model, and then turn off the power of the remote control. 3) If you use 3 channels, please set the failsafe protection of 3 channels to 1500.
