What is Hollow Shaft Stepper Motor? Hollow Shaft Stepper Motor is a type of stepper motor that features a hollow shaft or bore on its shaft. The hollow shaft can be categorized into three types, as explained by RobotDigg. Coarse Bore Hollow Shaft Stepper Motor A coarse bore hollow shaft stepper motor has a relatively rough machined bore and is used for applications where air, beams, or cables need to pass through. Examples of these motors include the Nema8, Nema11, Nema17, and others. Typical Applications Coarse bore hollow shaft stepper motors are commonly used in Pick and Place Machines like SMC Motor's OpenPnP, as well as in Robotics and Dynamic Robotic or Mobile Scanner applications. Screw Hollow Shaft Stepper Motor A screw hollow shaft stepper motor features a screw for lead screw purposes, also known as Non-captive Linear Stepper. When choosing this type of motor, it is essential to consider the pitch and lead. Precise Bore Hollow Shaft Stepper Motor In contrast to coarse bore motors, precise bore hollow shaft stepper motors have high precision on their hollow shafts without any screws inside. These motors are often used with bespoke ball screws in automation applications. They offer advantages such as reliability, neatness, space savings, and precision compared to traditional stepper motor and coupling combinations. Typical Applications Precise bore hollow shaft stepper motors are particularly useful when designing linear steppers for specific tasks, allowing users to customize the ball screw length and type later without affecting the overall design.
