FAQ:
Q1: Is the 12V system powerful enough?
Suitable for low-speed cruising and auxiliary propulsion of lightweight vessels, not suitable for high-speed or heavy-duty applications.
Q2: Can it be installed on inflatable boats or paddleboards?
Yes, with a suitable mounting bracket or base.
Q3: Is it noisy?
The brushless motor runs quietly, and the noise is minimal at low speeds.
Q4: Can it be used in saltwater?
Yes, but it is recommended to rinse with fresh water after use.
Q5: What do CW and CCW mean in the context of underwater thrusters?
DESCRIPTION OF THE UNDERWATER THRUSTERS CW AND CCW
Solution for underwater thruster packages that do not operate or only one thruster operates (demonstrated in the video using an upgraded version of the U92)：
The ESC is specially developed for underwater thrusters and has the following features:
1. The proprietary firmware of ApisQueen thrusters is specially designed to improve the superior performance of the thrusters. The motor PWM generated by the hardware can improve the smooth throttle response and reduce the noise.
2. ApisQueen's exclusive firmware will generate regenerative braking, making it more efficient. When the throttle changes from large to small, the thruster decelerates and responds more quickly, and the stability and flexibility of the thruster are significantly enhanced.
3. The ESC automatically detects the throttle signal when it is powered on, and supports 1-2ms pulse width input, Oneshot and Multishot in normal PWM throttle mode.
4. Support Dshot150, Dshot300 and Dshot600. Dshot is a digital signal with strong anti-interference ability, and the ESC does not need to calibrate the throttle stroke.
5. The signal wire is a twisted pair of silicone wires, which increases its service life and effectively reduces the interference caused by the signal transmission in the copper wire, making the thruster more stable.
ABOUT PWM
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.
