Ambient Temperature Range: -20°C~ +50°C Storage Temperature Range: -30°C~ +60°C Dielectric Strength: 500VAC 1min Number of Leads: 4 Motor Length: 34mm Shaft Diameter: 5mm (D-type) Torque vs. Speed Peak torque is ~0.28 N·m at low speed and drops off at higher stepping rates. The motor’s torque-frequency curve shows a high static (holding) torque of about 28 N·cm (0.28 N·m) at low speeds, which declines as the stepping frequency increases. In practical terms, this means full torque is available up to a few hundred steps/sec; beyond that, torque falls off due to inductance and limited current. Using microstepping can improve smoothness and usable torque at moderate speeds. Applications • 3D printers (e.g., extruder, X/Y/Z axes). • CNC machines and laser engravers. • Robotics and automation systems. • Precision positioning equipment.
