desertcart.com: YEJMKJ Nema 23 Stepper Motor 1.8‌°‌ 2 Phase High Torque 1.3Nm(184.1oz·in) Bipolar 57x55mm 4.2A 0.5Ω 4-Wire Shaft 21mm φ8mm 57 Stepper Motor Cable 1M for CNC Mill Lathe Router 3D Printer DIY Robot : Industrial & Scientific

## Features

- Size Specifications: Nema 23 Stepper Motor dimensional parameters are as follows. Body size 57x57x54.4mm, (2.25x2.25x2.15in), Installation hole distance 47mm, Shaft length 21±0.5mm, Shaft diameter φ8mm, D-cut length 21mm, with Cable 1m, 4-Wire Black (A+) Green (A-) Red (B+) Blue (B-), Weight 724g.
- Parameters: Nema 23 Stepper Motor 2 Phase, Step angle 1.8‌dge (200 steps/rev), Holding torque 1.3Nm (184.1oz·in), Resistance 0.5Ω, Rated current 4.2A, Inductance 1.2mH±20%, Rotor inertia approx 300g.cm².
- Operational Safety: This 57 mm Stepper Motor boasts safe and reliable operation, with the following key safety parameters. Dielectric strength 500V A.C 1 MINUTE; Insulation class(UL) B (130℃) [266°F]; Insulation resistance 100MΩ MIN; Temperature rise 80K MAX; Operation ambient temperature -20℃ ～+50℃ [-4°F～122°F]; Operation ambient humidity 15%RH～95%RH.
- Advanced Steel Construction: Leveraging reinforced steel cores and meticulously wound coils, this Nema 23 Step Motor offers up to 20% increased holding torque versus standard units. Benefit from a quieter operational profile and minimal environmental disturbance.
- Key Details: Faster speeds lead to lower torque, so the recommended range is 0–600 RPM. Lower current reduces torque and temperature rise, while lower voltage decreases torque (recommended range: 24–36V DC). Commonly used in 3D printers, DIY robots, CNC machines, and other automated systems, the Nema 23 Stepper Motor is compact yet provides high torque for heavy-duty tasks.

## Questions & Answers

**Q: What are the key characteristics of the stepper motors?**
A: They are known for high torque output, low noise, and robust construction. They typically have a step angle of 1.8 degrees and offer precise positioning control, making them ideal for applications requiring accuracy and strength.

**Q: Does it require a specific power supply?**
A: Yes. For optimal performance, we recommend a 24-36V DC power supply. Lower voltages will result in reduced torque. Additionally, while higher current settings increase torque, they also result in more significant motor heating.

**Q: What is the recommended operating speed range for YEJMKJ stepper motors?**
A: The higher the speed, the lower the torque. Recommended speed range: 0-600 rpm for open-loop motors.

**Q: What applications is this stepper motor compatible with?**
A: The motor delivers high torque, making it ideal for projects that require accurate positioning. The stepper motors find widespread use in applications such as CNC routers, engraving machines, DIY robot, and industrial automation systems.

**Q: What are the environmental operating conditions for this stepper motor?**
A: YEJMKJ stepper motors are built to perform in a wide range of environments, with an operating humidity range of 15% to 95% RH and a temperature range of -20°C to +50°C (-4°F to 122°F).
