Would the wave form of the rectified power cause an issue?** A: Probably not but i have not tried it. If there was a problem you could parallel a capacitor with the 36 volts to filter the noise. **Q: Is 100% command equivalent to running the motor directly connected to the power supply? My motors are not running as fast as expected.** A: There will be voltage drop, it cannot be helped. There will always be resistances to the circuit, series-pass element(s), the circuit board itself, etc, so you will always lose something. If you need true 100% then you'll have to resort to a bypass relay for a "max" setting when required. **Q: There is no fuse inside. What happens when it's overloaded? You must purchased another one? The 30a model at least has a 30a fuse inside the PCB.** A: If you overload it, it's gonna fry the circuits everytime.I've bought a few of these just to experiment with. I've also blown up a few. For the price, they're great speed controllers if you use them properly. ## Frequently Bought Together - tatoko DC Motor Speed Controller 10V-55V 12V 24V 36V 40A Stepless DC Motor Speed Controller with Forward-Brake-Reverse Switch,Ajustable Potentiometer &Digital Display - 10AWG Adapter for 40V Ryobi Lithium-ion Battery Dock Power Connector Wire Robotics --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.no/products/168554486-dc-motor-speed-controller-10v-55v-12v-24v-36v-40a](https://www.desertcart.no/products/168554486-dc-motor-speed-controller-10v-55v-12v-24v-36v-40a) --- *Product available on Desertcart Norway* *Store origin: NO* *Last updated: 2026-10-03*
