Compact 2 Phase 4 Wire Stepper Electronic Starter for Precision Motion Control This single piece stepper electronic starter is a compact, long pole 2 phase 4 wire stepping motor designed for small, precise actuation tasks. With a 6 mm diameter shaft and a configuration suited to camera lens adjustment, it provides controlled incremental motion for fine positioning and repeatable starts. Key benefits Precise incremental control: 2 phase stepper operation delivers accurate, repeatable microsteps for focus and positioning tasks. Reliable start behavior: designed as an electronic starter to provide consistent initial torque and smooth engagement when paired with compatible drivers. Space saving form factor: small diameter and long pole design fit into compact assemblies where axial reach and clearance matter. Easy integration: standard 4 wire wiring and common phase configuration make it compatible with many 2 phase stepper drivers and controller boards. Versatile use: suited to any application that requires small, controlled linear or rotational adjustments. Important specifications Quantity: 1 piece Shaft diameter: 6 mm Motor type: long pole stepping motor Phase: 2 phase Wiring: 4 wire Function: stepper electronic starter for adjustable camera lens and similar precision mechanisms Practical applications Camera lens focus modules: use as an adjustable electronic starter to control fine focus or zoom position in compact lens assemblies. Optical instruments and micropositioners: ideal for small stages, alignment screws, or any optical adjustment requiring precise incremental motion. Small automation and hobby projects: suitable for miniature robotics, gimbals, or custom mechanisms that need controlled starts and repeatable steps. Integration notes Designed to work with standard 2 phase 4 wire stepper drivers and controllers; confirm driver current and voltage match before connection. Check mounting space and shaft coupling for proper alignment and minimal axial play. For performance, verify wiring and configure driver step settings to match the motor step angle and desired resolution. This stepper electronic starter combines compact size, long pole reach, and a conventional 2 phase 4 wire interface to simplify integration into precision adjustment tasks, particularly camera lens and optical applications.
