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\u003ch3\u003e\u003cstrong\u003e170 kV\/290 kV Test Meter (Single Thruster)\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0621\/5493\/2452\/files\/170KV.jpg?v=1748483094\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0621\/5493\/2452\/files\/290KV.jpg?v=1748483094\"\u003e\u003c\/p\u003e","brand":"Underwater Thruster","offers":[{"title":"U8 170KV version \/ W300 RC-waterproof","offer_id":67678671864036,"sku":null,"price":412.0,"currency_code":"USD","in_stock":true},{"title":"U8 170KV version \/ A300 RC-Splash-proof","offer_id":67678671896804,"sku":null,"price":378.0,"currency_code":"USD","in_stock":true},{"title":"U8 290KV version \/ W300 RC-waterproof","offer_id":67678671929572,"sku":null,"price":452.0,"currency_code":"USD","in_stock":true},{"title":"U8 290KV version \/ A300 RC-Splash-proof","offer_id":67678671962340,"sku":null,"price":417.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0621\/5493\/2452\/files\/3_1d850f21-2156-45dd-bf7c-b50cf245f3b4.jpg?v=1792482610","url":"https:\/\/www.underwaterthruster.com\/tr-de\/products\/apisqueen-12v-24v-14-8kg-thrust-u8-underwater-thruster-two-set-with-remote-control-for-kayaks-and-paddleboards","provider":"Underwater Thruster","version":"1.0","type":"link"}
