: 0.84A per phase. Note that many community sources incorrectly estimate this at 1.5A; using the correct 0.84A is vital for setting accurate VREF on stepper drivers. Holding Torque : 2.86 kg·cm (approximately 0.28 N·m). Input Voltage : Maximum 24V DC. Dimensions : Height of 34mm (often referred to as a "42-34" motor). bj42d15 26v10 stepper motor datasheet exclusive
💡 To prevent overheating, ensure your stepper driver's Vref is tuned to deliver no more than 1.5A. For high-speed applications, use a 24V power supply to overcome back-EMF. The uses a BJ42D15 42 stepper motor powered
