However now the motor whines at low speed at the PWM freq. How can I stop the noise?** A: You might cure that with a capacitor with a voltage rating higher than the supply voltage, and perhaps a capacity rating of 100 mfd. This capacitor type is polarity rated, so you would need to put it across the terminals going to the fan in way you are supplying the voltage. You would also have to be sure not to reverse the power to make the fan go the other direction. capacitor could probably be as low as 20 mfd. It can be placed anywhere in the line, or right at the fan. The capacitor should smooth out the chopping voltage. As scott says, it might not list to run on low power. **Q: can this contoller switch be used for a razor motor scooter E 300 is 300 watts but if i put a 12 volt battery???** A: No. Your scooter will require a controller that will handle at least 25 amps (the formula is 300 watts, divided by 12 volts, equals 25 amps). This controller is rated at 3 amps continuous and 4 amps peak - at 12 volts that's only 36 watts continuous. **Q: I want to build an electric scooter. Is this a good reverse and speed controler for a DC 12v motor and battery** A: Actually - No, not if it's something you want to ride on. The circuitry in this is simply not heavy duty enough to handle that kind of load or that large a motor. This circuit is intended for something on the order of a toy motor, no more than an amp or two at most. **Q: Can anyone help me find a wiring diagram for this item please.** A: The third picture shows how to connect the power supply and the motor. That should be all you need. ## Frequently Bought Together - RioRand Upgraded Adjustable DC Motor Speed PWM Controller 10V 12V 24V 30V Reversing Switch 120W - BRINGSMART 12V 12rpm DC Worm Gear Motor 70kg.cm High Torque Self-Locking Reversed Mini Turbine Geared Motor for DIY Robot Rotating Table Door Lock Curtain Machine (12V 12rpm) - Bringsmart 370 Mounting Bracket with Screw Worm Gear Motor Fixed Fastener DIY Parts DC Motor Holder (Single-Side Bracket) --- ## 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.sn/products/3682598-riorand-pwm-dc-motor-speed-controller-10v-30v-3a-120w](https://www.desertcart.sn/products/3682598-riorand-pwm-dc-motor-speed-controller-10v-30v-3a-120w) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-07-18*
