Introduction
This is a commonly used stepper motor, model 42BYGH40-1.8-23A. It provides precise motion control with a step angle of 1.8°, supports microstepping drives, and ensures smooth movement and accurate positioning to meet high-resolution motion requirements. With strong and reliable power, it delivers a holding torque of up to 3.6 kg·cm, providing sufficient load capacity and ensuring stable, nonloststep operation over long periods. The motor features a compact and robust design, with a metal housing and standard mounting holes (4×M3), making it durable and easy to install. It operates with low power consumption and high efficiency, rated at 3.5V and 1.7A/phase, balancing power output with energy efficiency.
Widely applicable in 3D printers, robotics, automation equipment, small conveyor platforms, and other R&D projects, it offers stable performance and is ready to use upon installation.
Note: Before selecting the motor, please verify its rated torque, dimensions, mounting specifications, and other parameters to ensure the appropriate model is chosen.
