The heat sink gets barely warm after continuous running at reduced speed for hours. I'm planing to buy a few more of these for an industrial project. There a few things to be aware of however. The boards I received had quite a bit of solder flux residue on the bottom. This can be cleaned off easly with a little alcohol. The wiring on the potentiometer connector does not follow convention. The Red wire is ground , the Black wire is +5 V. Convention is the opposite. This controller is not going to use the pot but will be driven by a microcomputer. The external control works smoothly with 0 V being off and +5 V is full on. My take on the negative comments are as follows : The terminal connector not being wide enough can be solved by using a ring lug rather than a spade lug. This has worked out well on my test setup. The large 470 up capacitor exploding could be a failed cap. or over voltage. The application was a 90 V motor on a tread machine. The drive voltage was probably not regulated but just rectified line voltage which would exceed 100 V . So the 100 V cap. would be destroyed by over voltage. I recommend these units very highly. The cost is well below the cost of components and the PC board. Review: Good product. Works well for camera slider or turntable. - Perfect for running a small motor. I used a couple of these on separate projects to run small motors and they work well. Just 4 wires to connect - 2 to the battery supply and 2 to the motor and that's it. It is labelled right at the screw terminals for the wires so it's easy to connect up with no other instructions. Very smooth operation. It doesn't jerk at lower speeds like some others. I used them with the "HOSSEN Mini 12V DC 60 RPM High Torque Gear Box Electric Motor" and a couple of other motors in the same class also on desertcart. Cheap solution for a motorized camera slider or rotating turntable. I have one controlling a camera slider and it works perfectly and i have used it for many hours so far. I also have one turning a motorized turntable which i have put about 40 pounds of weight on and it works fine. I run it off 8 x D-cell batteries to get the 12v which works well. very pleased with this purchase. ## Features - Wide Voltage & High Current Compatibility：This PWM speed controller supports DC 6V-90V brushed motors, with 8A rated current (15A peak) and 0-100% adjustable speed via 16kHz PWM regulation. It delivers output voltage matching 0-100% of input voltage, compatible with motors up to 720W (90V×8A) for diverse low-voltage DC motor setups. - Dual Speed Control Modes：Adjust speed manually via the included B10K potentiometer (20cm wire, 8mm mounting hole) or remotely via 0-5V analog signal input—ideal for direct integration with PLCs, microcontrollers, and industrial automation systems to achieve precise motor speed control. - Comprehensive Safety Protections：Built with reverse polarity protection, over-voltage protection, and a 15A fast-blow ceramic fuse (5mm×20mm standard size) to safeguard the controller and motor from short circuits, power reversals, and overloads, ensuring stable long-term operation. - Compact & User-Friendly Design：Features terminal block wiring for easy installation, a compact footprint (64×59×28mm), and lightweight build (75g) for tight spaces. An optional external forward/reverse switch can be added to control motor direction, while the 0.005A standby current minimizes idle power consumption. - Versatile Application Scenarios：Suited for a wide range of projects: DIY robotics, model vehicles, small electric tools (drills, grinders), industrial automation (conveyors, mixers), brushless water pumps, and cooling fans—delivering reliable, efficient speed control for hobbyists and industrial professionals alike. - Note: Actual RPM depends on the connected DC motor. This controller supports 0-100% speed adjustment of your DC motor's maximum RPM. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00F839VNQ | | Best Sellers Rank | #75,266 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #40 in Motor Speed Controllers | | Brand | RioRand | | Brand Name | RioRand | | Customer Reviews | 4.3 out of 5 stars 656 Reviews | | Included Components | controller | | Item Dimensions W x H | 2.52"W x 1.1"H | | Manufacturer | RioRand | | Material | Iron | | Material Type | Iron | | Model | RR-6-90V-15A-PSC-CONS | | Model Name | RR-6-90V-15A-PSC-CONS | | Number of Items | 1 | | Part Number | RR-6-90V-15A-PSC | | Product Dimensions | 2.52"W x 1.1"H | | UPC | 606094322617 619636101304 | | Unit Count | 1 Count | | Warranty Description | 3 months | ## Product Details - **Brand:** RioRand - **Material:** Iron - **Model Name:** RR-6-90V-15A-PSC-CONS - **Number of Items:** 1 - **Product Dimensions:** 2.52"W x 1.1"H ## Images ![RioRand 6V-90V 15A PWM DC Brushed Motor Speed Controller – 0-5V Analog/PLC Control, Reverse Polarity Protection, for DIY Robotics & Industrial Automation - Image 1](https://m.media-amazon.com/images/I/71yABasl+SL.jpg) ![RioRand 6V-90V 15A PWM DC Brushed Motor Speed Controller – 0-5V Analog/PLC Control, Reverse Polarity Protection, for DIY Robotics & Industrial Automation - Image 2](https://m.media-amazon.com/images/I/71lH7bN0D+L.jpg) ![RioRand 6V-90V 15A PWM DC Brushed Motor Speed Controller – 0-5V Analog/PLC Control, Reverse Polarity Protection, for DIY Robotics & Industrial Automation - Image 3](https://m.media-amazon.com/images/I/71afrpK02lL.jpg) ![RioRand 6V-90V 15A PWM DC Brushed Motor Speed Controller – 0-5V Analog/PLC Control, Reverse Polarity Protection, for DIY Robotics & Industrial Automation - Image 4](https://m.media-amazon.com/images/I/71CEd-lCH-L.jpg) ![RioRand 6V-90V 15A PWM DC Brushed Motor Speed Controller – 0-5V Analog/PLC Control, Reverse Polarity Protection, for DIY Robotics & Industrial Automation - Image 5](https://m.media-amazon.com/images/I/71w6mT5RTuL.jpg) ## Available Options This product comes in different **Set** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good deal for a small motor controller *by G***N on May 24, 2023* I'm using this to drive a 24V 4 A motor.

Ribbon burners don't work without an external source of air flow. With a spare heater/air conditioner blower motor from my old Pontiac, I 3D printed an enclosure which turned it into a squirrel cage fan, and wanted to be able to adjust my air flow. After some research, I found these speed controllers here on Amazon, and decided to give them a try. THEY ARE AWESOME!!! I'm using a salvaged power supply from a desktop PC for my 12 volts, connected to this speed controller, which is then connected to the blower motor, and I could not be happier with the outcome! I now have one kick@$$ homemade ribbon burner setup for my forge, for a small fraction of what I'd have paid to buy one. Zero regrets with this purchase. Whenever I need a speed controller for any future projects, these will be my 'go to'. I'll be using the 2nd speed controller from this 2-pack to make a similar ribbon burner for my metal melting foundry. I'll post some videos here with my review very soon. You won't regret using these for your projects. I'd give these 10 stars if I could. ## Frequently Bought Together - RioRand Upgraded 6V-90V 15A DC Motor PWM Speed Controller 1PC - Greartisan DC 12V 550RPM Gear Motor High Torque Electric Micro Speed Reduction Geared Motor Centric Output Shaft 37mm Diameter Gearbox - ALITOVE DC 12V 5A Power Supply Adapter Converter Transformer AC 100-240V Input with 5.5x2.5mm DC Output Jack for 5050 3528 LED Strip Module Light --- ## 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.at/products/2008560-riorand-6v-90v-15a-pwm-dc-brushed-motor-speed-controller](https://www.desertcart.at/products/2008560-riorand-6v-90v-15a-pwm-dc-brushed-motor-speed-controller) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-09-03*
