| Specification | Typical Value | Why It Matters | | :--- | :--- | :--- | | | 1.5 - 2.5 Ohms | Determines heat generation. Lower resistance = higher current. | | Inductance | 2.0 - 3.5 mH | Affects torque at high speeds. Lower inductance = faster response. | | Current per Phase | 1.33A - 1.5A | Maximum continuous current. Exceeding this causes overheating. | | Holding Torque | 0.4 Nm (~55 oz-in) | The force the motor exerts to hold a position when stationary. | | Number of Leads | 4 | Indicates a bipolar stepper motor (most common for 3D printers). |
