Nema 17 BFISC42-P4A3 Integrated Linear Motion Stepper Servo Motor with Pulse Control (RS485,CANopen Optional) 42x42x80mm 1.68A 0.5N.m

The BFISC42-P4A3 is the highest-torque model in this NEMA 17 BFISC42 integrated linear motion family, providing 0.73 N·m rated torque. It uses a 42 × 42 mm frame, 1.8° step angle, 1.7 A current, 3.0 Ω resistance, 6.2 mH inductance, approximately 80.5–81.9 mm body length, and 0.61 kg weight, with 1000 PPR / 17-bit / 15-bit encoder options. Pulse control is standard, with RS485 Modbus RTU and CANopen versions available.

The BFISC42-P4A3 is designed for OEM applications requiring a high-torque NEMA 17 linear stepper motor with integrated driver while retaining the compact 42 mm mounting format. Besfoc's integrated design combines motor and driver functions, with DC 12–36 V input, a Cortex-M4 controller, up to 200 kHz pulse response, intelligent current regulation, reduced heating, anti-reverse connection protection, and optional IP30/IP54/IP65 protection. It can be configured with external T-type lead screws or ball screws for precise linear motion, making it suitable for X-Y tables, medical equipment, semiconductor handling, industrial multi-axis machines, food processing, and other automation applications.
