Review: Good motor.... - Motor is fine diving a small air compressor in my truck, the price was a little steep but it beats trying to find one surplus. ## Features - Measures 3.1 inches diameter (78 mm) by 5.8 inches long (147 mm) - No-load rpm: 5700 at 24 volts; Can be used with voltages ranging from 12V to 36VDC - Maximum power: 1580 watts (2.1 horsepower); Maximum stall torque: 10.6 Nm (1500 oz-in) - Peak efficiency at 24V: 79% at 29 amps and 5100 RPM - Power and torque at peak efficiency: 555 watts (0.75 horsepower) and 1030 mNm (145 oz-in) ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00AG21Q64 | | Best Sellers Rank | #1,224,242 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #427 in Permanent Magnet Motors | | Date First Available | November 30, 2012 | | Is Discontinued By Manufacturer | No | | Item Weight | 5.79 pounds | | Item model number | E30-400 | | Manufacturer | AmpFlow | | Package Dimensions | 10.7 x 4.4 x 4.3 inches | ## Images ![E30-400 Brushed Electric Motor, 12V, 24V or 36 VDC, 5700 RPM - Image 1](https://m.media-amazon.com/images/I/617NwzUj4WL.jpg) ## Questions & Answers **Q: can this motor run continuously?** A: Yes, as long as you keep the output below about 250W. **Q: Hello, can you tell me the maximum amperage draw this motor can create? I want to by a DC speed controller for this unit. Thanks for your help :)** A: The locked rotor current is around 275 amps at 24volts. I would limit the current to 30 amps continuous and perhaps 75 amps peak as the leads are only 12AWG and heat would be a concern if used over 30 amps long term. **Q: i will be installing this motor on a 12volt system. i would like to have an inline fuse, but need to no what amp fuse i should use?** A: Hi, I didn't test yet but per my numbers a 15-20 Amps fuse should be fine. **Q: What is the output shaft diameter, and can the motor be easily wired for variable speed (like with a rheostat)?** A: The shaft is 1/2-inch diameter. Yes, the motor can run at variable speeds and reverse. An electronic motor speed controller is normally used for this rather than a rheostat. ## Customer Reviews ### ⭐⭐⭐⭐⭐ First day install... *by A***R on December 17, 2024* Functions as advertised. ### ⭐⭐⭐⭐ Good motor.... *by H***Y on May 30, 2015* Motor is fine diving a small air compressor in my truck, the price was a little steep but it beats trying to find one surplus. ### ⭐⭐⭐⭐⭐ AmpFlow E30-400 *by S***1 on February 8, 2014* Small, sleek, light and the power is very impressive, I will definitely be buying another. You need to understand it's limitations like anything else, take care of it and it will last along time. Regardless of where it was made or who the outfit is, it really is well made and feels solid. Although it was packaged well, the only negative I have to say is, that I would ask for another shipper, I will not be using that brown outfit again, I am sure you know who I mean. ## Frequently Bought Together - AmpFlow E30-400 Brushed Electric Motor, 12V, 24V or 36 VDC, 5700 RPM - Jeremywell #25 Roller Chain Sprocket B Type 1/2'' Bore Hardened 30 Tooth --- ## 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.co.th/products/3902286-e30-400-brushed-electric-motor-12v-24v-or-36-vdc](https://www.desertcart.co.th/products/3902286-e30-400-brushed-electric-motor-12v-24v-or-36-vdc) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-04-27*
