What Is A Linear Stepper Motor?

Linear stepper motors, or linear stepper motors, are made of a magnetic rotor core that rotates by interacting with a pulsed electromagnetic field generated by a stator, and linear stepper motors convert rotary motion into linear motion within the motor.

The basic principle of a linear stepper motor: a screw and nut are used to engage, and some method is adopted to prevent the screw and nut from rotating relative to each other, thus allowing the screw to move axially. Generally speaking, there are two ways to realize this transformation, the first is built in the motor with a rotor with internal threads to rotor threads and screw engagement to achieve linear motion, the second is to screw as a motor out of the shaft, in the motor outside through an external drive nut and screw engagement to achieve linear motion. The result is a greatly simplified design that enables precision linear motion in many applications to be achieved directly with linear stepper motors without the installation of an external mechanical linkage. Linear stepper motors are used in a wide range of applications including manufacturing, precision calibration, precision fluid measurement, precise positional movement, and many other areas where high precision is required.

Linear Stepper Motor FAQ

  • Q How to choose correctly linear Stepper motor Manufacturer & Supplier

    A When choosing a linear stepper motor manufacturer and supplier, the following aspects need to be considered,When choosing a linear stepper motor manufacturer and supplier, consider factors such as product quality, reliability, customization options, customer service, and after-sales support.

    Linear Stepper Motor Quality

    Materials and Manufacturing Processes：

    Inquire about the materials used and ensure they employ advanced manufacturing techniques like precision machining and assembly for consistent quality.

    Quality Control Standards：

    Check if the supplier has certifications like ISO 9001 and conducts rigorous inspections at various production stages.
     

    Linear Stepper Motor Range

    Diverse Models and Specifications：

    A good supplier should offer a wide selection of linear stepper motors, including different sizes, step angles, torque ratings, and lead screw pitches.

    Customization Capabilities：

    The ability to customize motors according to specific requirements, such as special dimensions, mounting methods, or performance parameters, is valuable.

    Technical Expertise and Support

    Experience and Knowledge：

    Look for suppliers with extensive experience in the linear stepper motor field, who can provide professional advice on motor selection and application.

    Technical Support Services：

    They should offer comprehensive technical support, including pre-sales consulting, installation guidance, and after-sales troubleshooting.

    Delivery and Service

    Delivery Time and Reliability：

    Ensure the supplier can meet delivery deadlines and has a reliable delivery system to avoid project delays.

    Customer Service：

    Good communication and responsiveness are crucial.   The supplier should be able to address inquiries and concerns promptly.

     

    Price and Cost Performance

    Competitive Pricing：

    While price is important, don't solely focus on the lowest cost.   Consider the overall value, including quality, performance, and service.

    Cost-Effectiveness：

    Evaluate the long-term cost-effectiveness of the product, including energy consumption, maintenance requirements, and service life.

  • Q How does a linear stepper motor work?

    A A linear motor works by threading a screw to convert rotary motion into linear motion, thus realizing a linear function.

  • Q How many types of linear motors are there?

    A There are three types of linear stepper motors: fixed shaft (captive), through shaft (non-captive), and externally driven.

  • Q What is the difference between the three types of motors?

    A Fixed axis (captive): The motor has an internal anti-rotation mechanism, the central axis can not be rotated, and will only move forward and backward to realize the function of linear motion.
    Non-captive: The center shaft of the motor is not fixed by the anti-rotation mechanism, it can rotate, but the customer needs to add the anti-rotation mechanism to make the center shaft can not rotate, otherwise the center shaft will rotate in the same place and can not work properly.
    External driving: the output shaft of the motor is matched with a nut, and the customer can assemble the required moving parts on the nut to realize the function through the back and forth movement of the nut.

  • Q What are the most important parameters for linear motors?

    A The most important parameters for linear motors are thrust, speed, stroke and motor size.
    Thrust is the linear push and pull force that the motor's screw can provide. The unit is usually Newton or weight.
    Customers in the linear motor product selection, thrust is the first consideration.

  • Q What is the impression of the thrust of a linear motor?

    A The thrust of a linear motor is influenced by the size of the motor and the lead of the screw.
    The larger the size of the motor, the greater the corresponding thrust.
    For the same size, the smaller the lead, the higher the thrust.

  • Q What is Lead? How does it affect the parameters of a linear motor?

    A Lead refers to the linear motor's screw rotates one week, the output shaft or nut movement of the straight line distance.
    For motors of the same size:
    The larger the Lead means the faster the linear speed, but correspondingly the smaller the linear thrust.
    A smaller Lead means slower linear speeds, but correspondingly higher linear thrust.
    Customers need to choose the appropriate screw lead based on the thrust and speed requirements of their projects.

  • Q What is the maximum travel of a linear stepper motor?

    A The stroke of our linear motors can be customized.
    However, the maximum stroke is generally limited by the size of the motor and the diameter of the screw.
    Excessive length of the screw will have the risk of deformation and bending of the screw, so we recommend choosing the appropriate stroke according to the motor and the screw.

  • Q What other items can be customized?

    A All parameters of the motor, including resistance, lead, stroke, wire length, connectors, etc. can be customized.
    If you need to select a linear stepper motor for your new project and have it customized, please feel free to contact our sales team.

  • Q Where are linear stepper motors typically used?

    A Linear stepper motors are used in a wide range of applications.
    Stepper motors have the advantage of precise control, while linear motors can realize linear motion.
    Theoretically, linear stepper motors can be used in any development project that requires precise control of linear motion.
    Linear stepper motors can be used in small electronic products, such as the focusing function of a camera/lens, as well as in the motion function of a production line for large instruments.

  • Q What is the life expectancy of a linear stepper motor?

    A The life of a stepper motor varies greatly according to different working conditions, such as: working hours, load size, running speed, etc. Especially the load size, which directly affects the life of the screw.
    We are unable to conduct life test according to all different loads and working conditions.
    If the customer has special needs for life, we can perform life tests according to the working conditions specified by the customer.

  • Q What can I do to reduce the noise of linear stepper motors? How can I prevent the motor from losing steps?

    A Generally speaking, the noise of stepper motors is relatively small compared to other motor types.
    However, when the thrust of the motor is less than the load, the motor will lose steps, which will cause the motor to become noisier.
    Here are some suggestions on how to solve this problem:
    A. Replace the motor with a larger one
    B. Decrease the drive frequency/reduce the travel speed.
    C. Increase the drive motor/increase the drive current.
    D.Improve the assembly precision of the product to avoid the motor being stuck.
