Difference between unidirectional ESC and bidirectional ESC

This article explains the difference between unidirectional ESC and bidirectional ESC

First, we demonstrate bidirectional ESC, using 30A Feather ESC and 16V power supply voltage.

Turn on the remote control and connect the ESC plug to the power plug.

Connect the three-phase line of the propeller to the three-phase line of the ESC.

Connect the signal line of the ESC to the receiver, and insert the signal line into channel 1 or channel 2. Pay attention to the direction of connection. The white line is connected in the direction marked with numbers.

After connecting the power supply, wait for the ESC to pass the self-test (wait for the prompt sound to stop).

Push the remote control joystick upward, the propeller blows air forward and drives forward;

Pull the remote control joystick downward, the propeller blows air backward and drives backward.

If the front and rear air outlet order is incorrect, you can change the direction of rotation of the blades by swapping any two of the three-phase lines.

If not in use, please disconnect the power supply and then turn off the remote control.

Next, we demonstrate the unidirectional ESC and connect the three-phase line of the propeller to the three-phase line of the ESC.

Connect the signal line of the ESC to the pwm (before connecting, adjust the knob to 1ms), insert the signal line into any of the three ports, pay attention to the direction of connection, and insert the white line downward.

Connect the ESC to the power supply, wait for the ESC to pass the self-test and then use it.
Turn the knob and the propeller will start.
If the order of air outlet is not correct, you can change the direction of propeller rotation by swapping any two of the three-phase lines.
It should be noted that the one-way ESC can only make the propeller rotate in one direction, that is, it can only move forward or backward, and cannot move forward and backward, turn left and right like the two-way ESC
