How to Use a Can Stack Stepper Motor for Medical Devices


Introduction to Can Stack Stepper Motors

Can Stack Stepper Motors have gained significant popularity in various industries, including medical devices. These motors offer precise and controlled motion, making them an ideal choice for applications where accuracy and reliability are vital. In this article, we will delve into the functionality, advantages, and the efficient utilization of Can Stack Stepper Motors in medical devices.

Understanding Can Stack Stepper Motors

Can Stack Stepper Motors are designed with a cylindrical shape and consist of multiple stacks of laminations. Each lamination comprises toothed grooves that fit perfectly with the rotor, ensuring precise rotational movement. This design allows for fine control over the motor's position, velocity, and torque.

These motors operate based on the principle of electromagnetism. By energizing and de-energizing the coil windings within the stator, a linear sequence of steps is generated. These steps translate into rotational movement, enabling precise positioning without the need for feedback sensors.

Advantages of Can Stack Stepper Motors in Medical Devices

3.1 Enhanced Precision and Accuracy

Can Stack Stepper Motors provide exceptional control over motion, allowing for precise and accurate positioning. This is crucial in medical devices that require exact movement for procedures, such as medical imaging equipment, robotic surgery systems, and drug dispensing devices. The high resolution and repeatability of these motors enable consistent and reliable performance.

3.2 Compact Size and High Torque

The compact size of Can Stack Stepper Motors makes them suitable for medical devices with limited space. Despite their small form factor, they can deliver substantial torque, ensuring efficient operation even with demanding tasks. This characteristic is particularly advantageous in applications like prosthetics and exoskeletons, where compactness and high torque are essential.

3.3 Cost-Effective Solution

Due to their simplicity and ease of use, Can Stack Stepper Motors offer a cost-effective solution for medical device manufacturers. These motors do not require complex feedback systems and can function reliably in open-loop configurations. The absence of feedback systems not only reduces costs but also simplifies the overall design and control of medical devices.

3.4 Improved Energy Efficiency

Can Stack Stepper Motors convert electrical energy into mechanical energy with high efficiency. They consume power only when steps are taken, and the motor's holding torque ensures that it remains stationary when not in use. This characteristic minimizes wasted energy and contributes to the overall energy efficiency of medical devices, making them more environmentally friendly.

Utilizing Can Stack Stepper Motors in Medical Devices

4.1 Medical Imaging Equipment

Medical imaging equipment, such as CT scanners, MRI machines, and ultrasound devices, rely on precise positioning systems for accurate imaging. Can Stack Stepper Motors offer the required precision and control to move various components, including X-ray detectors, gantries, and robotic arms in these devices. Their ability to make microscopic adjustments aids in capturing detailed images and improves the diagnosis process.

4.2 Robotic Surgery Systems

Can Stack Stepper Motors play a critical role in robotic surgery systems, enabling precise movement of surgical tools and robotic arms. They provide the necessary accuracy and reliability to perform delicate procedures with minimal invasiveness. Surgeons can benefit from the ability to control the position and orientation of surgical instruments with high precision, resulting in improved surgical outcomes.

4.3 Drug Dispensing Devices

Efficient drug dispensing devices require precise control of medication dosage and delivery. Can Stack Stepper Motors offer accurate and repeatable motion control for precise drug dispensing, ensuring patient safety and medication efficacy. By utilizing these motors, healthcare professionals can rely on consistent and controlled medication administration, reducing the risk of errors.

4.4 Prosthetics and Exoskeletons

Can Stack Stepper Motors find application in prosthetics and exoskeletons, where compactness and high torque are essential. These motors enable smooth and precise movement in artificial limbs, replicating natural human motion. Additionally, they provide the required torque to support individuals with limited mobility, enhancing their ability to perform daily tasks and improving their overall quality of life.

4.5 Rehabilitation and Physical Therapy Devices

In rehabilitation and physical therapy devices, where controlled motion is crucial for patient recovery, Can Stack Stepper Motors offer precise and adjustable movement. These motors can be integrated into devices like exercise machines, rehabilitation robots, and mobility aids, facilitating targeted therapy and regaining muscle strength. The ability to control the stepper motors allows medical professionals to customize therapy sessions based on individual patient needs.


Can Stack Stepper Motors have revolutionized the medical device industry, offering precise positioning, compactness, high torque, and energy efficiency. From medical imaging equipment to rehabilitation devices, these motors enhance the accuracy, reliability, and performance of critical medical applications. With the continuous advancements in motor technology, Can Stack Stepper Motors are poised to play an increasingly vital role in shaping the future of medical devices.
