The BFISC57-P5A3 is a high-output integrated linear stepper motor featuring an external ball lead screw and Pulse control. It provides a 1.8° step angle, 4.2 A phase current, 0.75 Ω phase resistance, and 3 mH phase inductance, generating 2.8 Nm rated torque. The motor has a 116.5 mm body length and weighs 1.6 kg, providing increased mechanical output for demanding linear motion applications. It uses Class B insulation and supports single-turn and multi-turn absolute encoders for reliable position feedback. The integrated configuration helps simplify machine design by combining motion generation, linear transmission, and feedback functions. BFISC57-P5A3 is suitable for industrial automation, heavy-duty linear positioning, CNC equipment, robotic machinery, precision actuators, and customized OEM motion-control solutions.
