(1) ESC built-in thruster, direct water-cooling, can continue to stabilize the maximum throttle output.
(2) Very small current, increase battery life, reduce battery cost, wider choice of batteries, ordinary car batteries can also be used.
(3) Wide voltage support, 24V version can support up to 30V, 48V version can support up to 50.2V voltage.
(4) Modular design, easy to install, disassemble and carry.
(5) large thrust, can push 3-4 people kayak or inflatable boat, etc..
(6) High quality, anti-corrosion, can be used in seawater freshwater environment.

AQ1020 use environment: seawater/freshwater


PWM full name is (Pulse-width modulation). It is also called duty cycle signal, which indicates the proportion of the high level duration to the whole signal period. 2ms for the whole period of PWM, 1.5ms stop, 1.5-2ms forward, 1.5-1ms reverse.

From the diagram, we can clearly see that when PWM is 75% (1.5ms), the motor stops rotating, when PWM is 50% (1ms), the motor rotates in reverse, and when PWM is 100% (2ms) the motor rotates in forward.Of course ESC will not only make the motor turn forward and reverse, but can adjust the speed of motor rotation by the duty cycle size of PWM. When the PWM is gradually changed from 75% to 50%, the motor will keep reversing and accelerating from stop until the reverse rotation reaches the maximum. And when PWM is gradually changed from 75% to 100%, the motor is continuously accelerated from stop to forward until the forward rotation reaches the maximum value. That is, PWM is a signal that can be continuously varied, and the effective range is from 50% to 100%.

The frequency of PWM signal is 50hz, 100hz, 200hz or 500hz, etc. The higher the control frequency, the shorter the period, the shorter the control interval, and the faster the ESC and motor response speed The faster the ESC and motor response. Conversely, the lower the control frequency, the longer the period, the longer the control interval, and the slower the ESC and motor response.
