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.\u003c\/p\u003e\n\u003cp align=\"start\"\u003e2. 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.\u003c\/p\u003e\n\u003cp align=\"start\"\u003e3. 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.\u003c\/p\u003e\n\u003cp align=\"start\"\u003e4. 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.\u003c\/p\u003e\n\u003cp align=\"start\"\u003e5. 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eABOUT PWM \u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003ePWM 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\u003cspan\u003e \u003c\/span\u003ethe whole period of PWM, 1.5ms stop, 1.5-2ms forward, 1.5-1ms reverse.\u003c\/p\u003e\n\u003cp\u003eFrom the diagram, we can clearly see that when PWM is 75% (1.5ms), the motor stops rotating, when\u003cspan\u003e \u003c\/span\u003ePWM 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\u003cspan\u003e \u003c\/span\u003erotation by the duty cycle size of PWM. When the PWM is gradually changed from 75% to 50%, the motor\u003cspan\u003e \u003c\/span\u003ewill keep reversing and accelerating from stop until the reverse rotation reaches the maximum. And when\u003cspan\u003e \u003c\/span\u003ePWM is gradually changed from 75% to 100%, the motor is continuously accelerated from stop to forward\u003cspan\u003e \u003c\/span\u003euntil the forward rotation reaches the maximum value. That is, PWM is a signal that can be continuously\u003cspan\u003e \u003c\/span\u003evaried, and the effective range is from 50% to 100%.\u003c\/p\u003e\n\u003cp\u003eThe frequency of PWM signal is 50hz, 100hz, 200hz or 500hz, etc. The higher the control frequency, the shorter\u003cspan\u003e \u003c\/span\u003ethe period, the shorter the control interval, and the faster the ESC and motor response speed The faster the\u003cspan\u003e \u003c\/span\u003eESC and motor response. Conversely, the lower the control frequency, the longer the period, the longer the\u003cspan\u003e \u003c\/span\u003econtrol interval, and the slower the ESC and motor response.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0621\/5493\/2452\/files\/468ef44610c31b5b50b747b4f9f5ee49_23b2aca3-3420-4da7-a0c8-601450ad7f3b.jpg?v=1700809819\u0026amp;width=700\" alt=\"\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAPISQUEEN U2\/U2mini underwater thruster mounting base, can be purchased if necessary：\u003c\/strong\u003eAPISQUEEN U2\/U2mini underwater thruster mounting base\u003c\/p\u003e\n\u003cp\u003e\u003cimg alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0621\/5493\/2452\/files\/U2_6a0f13cb-1272-4f2c-bcf2-f1ffa43f6b15.jpg?v=1747710392\u0026amp;width=700\"\u003e\u003c\/p\u003e\n\u003cblockquote\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan style=\"color: rgb(255, 128, 0);\"\u003eAbout points (lower right corner of the store page):\u003c\/span\u003e\u003c\/strong\u003e\u003cbr\u003e★5 points for every $1 spent;\u003cbr\u003e★For every 100 points redeemed, you can get a $1.00 discount on the entire order;\u003cbr\u003e\u003cspan style=\"color: rgb(230, 150, 135);\"\u003eApplicable to orders of any amount.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow to use points:\u003c\/strong\u003e\u003cbr\u003e1.
