Two phase, fourwire 43MM stepper motor (Model BJ02) with bracket, slider and screw rod — precision stepping motor designed for compact imaging and precision linear motion applications. Why customers choose this motor Precise, repeatable positioning: The two phase, fourwire stepping design provides fine incremental motion control for tasks that require accurate stops and starts. Readytomount linear actuation: The included bracket, slider and screw rod convert rotary steps into smooth, controllable linear travel without sourcing separate mechanical parts. Compact footprint: With a 43MM form factor, this motor fits into small assemblies where space is limited, making it ideal for compact imaging equipment and tight mechanical layouts. Cameraready application: Specified with Round Digital Camera in mind, this unit is suited to precision camera mechanisms such as focus or microadjustment stages. Key features and attributes Motor type: Two phase, four wire stepper motor (bipolar wiring configuration). Size: 43MM compact motor body for spaceconstrained designs. Model: BJ02. Mechanical accessories: Supplied bracket, slider and screw rod for straightforward mounting and linear motion conversion. Functionality: Precision stepping for controlled incremental motion and reliable repeatability. Compatibility: Fourwire connection supports standard bipolar stepper driver control schemes and common motion controllers. Use in assemblies: Bracket and slider simplify integration into camera housings, lens modules, or precision stages. How this motor solves common problems Eliminates the need to source separate linear hardware by combining motor and screw rod into one kit, reducing integration time and mechanical complexity. Provides consistent, repeatable positioning to avoid focus drift or misalignment in imaging systems. Small size and included mounting bracket make it simple to fit into compact devices without extensive design rework. Typical applications and use cases Camera focus or lens microadjustment: Use the stepper for precise AF/MF actuation or finefocus mechanisms in round digital camera assemblies and compact imaging modules. Miniature camera slider or timelapse actuator: Drive controlled linear movement for short travel camera sliders used in macro photography, product shots, or timelapse rigs. Precision optical alignment and smallstage motion: Integrate into imaging instruments or small optical benches where accurate incremental motion and easy mounting are required. What to expect when integrating Electrical interface: Fourwire bipolar connections; plan for a compatible stepper driver and controller. Mechanical integration: Use the supplied bracket and slider to mount and secure the motor and connect the screw rod to the moving element for linear motion. Performance characteristics: Designed for precise positional control and repeatability typical of twophase stepping motors (refer to your driver/controller settings for step resolution and motion profiles).
