Resistance accuracy: +-10%. Inductance accuracy: +-20%. Temperature rise: 80deg max (rated current, 2 phases) Ambient temperature: 20 deg - +50 deg. Insulation resistance: 100 ohms min, 500 vdc Insulation strength: 500 VAC for one minute. Use or use: The spool is made of 100% pure copper enamelled wire. The copper wires are arranged evenly, and it is not prone to problems such as excessive temperature, torque deterioration and increased noise after long-term operation. The magnetic steel is high quality, we normally use the SH level type. The rotor is coated, reduces burrs, works smoothly, less noise. We test the stepper motor parts step by step. Stator is tested and rotor is tested before assembly. After assembling the stepper motor, we will perform another test to ensure the quality is good. These products are widely used in engraving machines, printers, medical equipment, embroidery machines, stage lighting, textile automation, printing, packaging and other industrial automation equipment. Review: Guter Motor - Ware ist pünktlich und gut verpackt bei mir angekommen. Der Motor ist sehr gut und leise. Leider fehlt eine Anschlußbelegung, die es nur im Internet gibt. Trotzdem alle Sterne. Gerne wieder auch in anderer Größe und Ausführung. Review: Arrivato nei tempi previsti - Arrivato nei tempi previsti ,lo devo ancora testare ma dall'aspetto e realizzato bene e il prezzo e molto conveniente , appena lo avrò messo in funzione aggiornero la recensione. ## Features - Very high torque 2.8 Nm (425 oz.in) holding torque - Size: 57 x 57 x 112 mm; 1.8 degrees; rated current 3 A; wave: double wave; connection cable: 4 pieces; phase: 2; type: hybrid - The spool is made of 100% pure enamelled copper wire and is wrapped with advanced technology. The copper wires are arranged evenly, and it is not prone to problems such as excessive temperature, torque deterioration and increased noise after long-term operation. - The surface of the rotor is coated with high quality epoxy resin so that the surface of the rotor does not attract dust. The magnetic field of the motor is more stable, the torque is larger and the motor runs quietly and stable, with low noise and long service life. - These products are widely used in engraving machines, printers, medical equipment, embroidery machines, stage lighting, textile automation, printing, packaging and other industrial automation equipment ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07HQ5T7SL | | Best Sellers Rank | 41,889 in Business, Industry & Science ( See Top 100 in Business, Industry & Science ) 24 in 3D Printer Motors | | Brand | RATTMMOTOR | | Country Of Origin | China | | Customer Reviews | 4.1 out of 5 stars 17 Reviews | | Horsepower | 425 Watts | | Manufacturer | RTM | | Manufacturer Part Number | 23HS2430B | | Material | Alloy Steel , Copper | | Model Number | 1PCS | | Speed | 12000 RPM | | UPC | 634769120299 | | Voltage | 500 Volts | ## Product Details - **Brand:** RATTMMOTOR - **Horsepower:** 425 Watts - **Material:** Alloy Steel, Copper - **Speed:** 12000 RPM - **Voltage:** 500 Volts ## Images ![Nema23 CNC Stepper Motor 425oz-in 112mm 3A 2.8N.m 1.8° 4 Connection Wire for CNC Router Engraving Milling Lathe - Image 1](https://m.media-amazon.com/images/I/71RTpajPOwL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Guter Motor *by E***2 on 26 December 2023* Ware ist pünktlich und gut verpackt bei mir angekommen.
