To select a custom linear motor, define the motion your machine must produce, then match the motor, drive, feedback system, and mechanical arrangement to that requirement. Start with travel, moving mass, speed, acceleration, force, duty cycle, accuracy, and the installation environment. These inputs help a supplier assess whether an iron-core, ironless, or tubular design is suitable and identify which parts of the system need customization. At Mingzhi Da, we recommend sharing the application and operating conditions before requesting a quotation, so the discussion can focus on a workable specification rather than a motor name alone.
This guide is for equipment manufacturers, automation integrators, and procurement teams considering a linear motor for new equipment or a motion-system redesign. It is especially useful when a standard catalog configuration does not match the required stroke, mounting space, load, or feedback arrangement. Use it to prepare a clear technical brief for supplier discussions. Final sizing should be confirmed against the complete machine design and the selected motor and drive documentation.
A linear motor produces motion along a straight path directly, rather than converting rotary motion through a belt, screw, or gearbox. A typical system includes a motor forcer or coil assembly, a magnet track or other reaction section, a servo drive, and a feedback device when closed-loop positioning is required. The motor itself does not provide a complete guided axis, so bearings, structural support, cable management, and protective features may also be needed. This distinction matters when comparing a motor specification with the performance of a finished linear stage.
These categories are starting points, not a substitute for comparing actual motor curves and system requirements. Design details differ among manufacturers, so ask for the relevant technical data for the proposed configuration. A motor type that is suitable for one axis may not be the best choice for another. Consider the complete motion system, including the drive and mechanical guide.
Linear motors are used in equipment that needs controlled straight-line movement, such as inspection systems, pick-and-place machinery, packaging equipment, semiconductor-related equipment, and automated production lines. The application determines which characteristics matter most: a positioning axis may prioritize repeatability, while a transfer axis may place more emphasis on travel, speed, or force. Cleanliness, dust, washdown exposure, temperature, and available installation space can also affect the design. Describe the process and operating environment, not just the machine category.
For example, an early design brief might specify a 500 mm travel, a 20 kg moving mass, and a target speed of 1 m/s. These figures are illustrative inputs, not a recommended motor specification or a performance claim. Required thrust also depends on acceleration, friction, orientation, cable forces, and any external process load. A supplier needs these factors to assess continuous and peak force requirements.
State the required travel, moving mass, speed profile, acceleration, and cycle pattern. Distinguish between continuous force and peak force, and explain how long peak force is needed and how often the machine repeats the move. Include the axis orientation and any external force from tooling or the process. A motor that meets a brief peak-force target may still be unsuitable if its continuous thermal requirement is not addressed.
Specify the required positioning accuracy and repeatability for the complete axis, rather than assuming these are determined by the motor alone. Mechanical alignment, guide quality, feedback resolution, controller settings, and operating conditions all contribute to system behavior. Tell the supplier which controller or drive platform you plan to use, if known, and identify any required encoder type or communication interface. If these details are undecided, ask for compatible options and the information needed to choose between them.

Share the expected duty cycle, ambient temperature, heat-removal constraints, and whether cooling is available or permitted. Explain exposure to dust, moisture, oil, vibration, or cleaning chemicals so the supplier can discuss suitable protection and installation practices. Do not assume that a motor’s environmental suitability follows from its general product category. Confirm relevant limits and protection details for the exact proposed configuration.
Customization may involve motor dimensions, travel arrangement, mounting features, cable exit direction, feedback selection, connector requirements, or integration with a customer-defined axis. Some requests may affect the motor design, while others may be handled through brackets, covers, or system-level components. Provide interface drawings, available space, and any restrictions on moving cables or access for maintenance. Ask the supplier to identify which requested features are confirmed, optional, or dependent on further engineering review.
Custom linear motor pricing depends on the selected motor and drive, feedback components, mechanical integration, customization scope, and required documentation. Minimum order quantities and lead times can also vary with the design, component availability, and whether the request is for evaluation units or production supply. These details cannot be reliably inferred from the phrase “custom linear motor” alone. Request a quotation that separates the proposed configuration, included components, commercial assumptions, and any tooling or engineering charges.
For planning, ask the supplier to confirm the sequence for technical review, drawing approval, sample or prototype supply, and production orders. Clarify what changes after design approval may affect cost or schedule. If a project has a fixed launch date, communicate it at the start and ask what information is needed to assess feasibility. Treat any schedule as subject to confirmation against the agreed scope and sourcing conditions.
Use these questions to make supplier discussions more specific and comparable. They help reveal whether a proposal addresses the application as a complete motion system or only quotes a motor component. Request written answers and supporting technical documents where available. If a point is not yet confirmed, record it as an open item rather than making an assumption.
A frequent mistake is choosing a motor based only on maximum force or speed without checking the actual motion profile and duty cycle. Another is treating motor accuracy as equivalent to finished-axis accuracy, even though guides, mounting, feedback, and control also matter. Buyers may also overlook cable forces, orientation, thermal limits, or environmental exposure until late in integration. Provide these details early and ask the supplier to explain any assumptions used in the proposed sizing.
A suitable custom linear motor is selected by matching its force, travel, speed, thermal behavior, feedback, and interfaces to the real machine requirements. Begin with an application brief that includes the motion profile, load, duty cycle, accuracy target, environment, and available space. Then compare motor types and customization options with the supplier, confirming what is included in the complete axis and what remains the machine builder’s responsibility. The illustrative values in this guide are examples only; they should not be treated as a sizing recommendation.
To move the project forward, send Mingzhi Da your application description, preliminary specifications, layout drawings, and target sourcing schedule. We can use those details to discuss a suitable custom linear motor configuration, identify open technical questions, and prepare a quotation for review. If some requirements are still being defined, share the known constraints first so the next steps can be agreed efficiently.
