42-stepper motor driver kit, TB6600 4A module with 17HS4401S 0.4NM motor for electronic projects

Discover our 42 stepper motor assembly, a high-performance solution designed for reliability and efficiency. This assembly includes 1 motor, 1 driver, and 1 connecting cable. Our motor stands out thanks to its superior technical specifications and robust construction. The winding is made of pure enameled copper wire, thanks to a precision winding process. The silicon steel structure is uniformly arranged, which helps maintain a lower temperature rise during operation. This design ensures high stability, preventing any deformation or annoying noise, even during intensive and prolonged use. The use of silicon steel bearing material enhances durability and guarantees a long service life. The rotor surface is treated with a high-quality imported adhesive, and the textile silicon steel is oxidized after machining to effectively reduce burrs. Compared to standard products in the industry, this motor offers higher torque, more stable output, and a remarkably low noise level for quieter operation. **Detailed Technical Specifications:** **Item Type:** 42 Stepper Motor Drive Assembly **Number of Phases:** 2 **Rated Voltage:** DC 3.6V **Phase Resistance (at 20°C):** 2.4 x (1±15%) Ω/phase **Holding Torque:** ≥ 420 mN.m **Connection Sequence (View from Shaft):** A-AB-B-CW (Clockwise)
