Printed Circuit Board Stator for Next Generation Electrical Motors

The increasing popularity of printed circuit board (PCB) motors can be attributed to their compact design, lightweight, and excellent efficiency. Engineers and designers leverage specialized software to create, simulate, and optimize PCB motor designs. Below, we will discuss the leading PCB motor design software available in the market, along with its features, capabilities, and limitations.


Software for PCB Motor design

The three design software, Altium Designer, Ansys Maxwell Infolytica motor solve, and MATLAB/Simulink are specifically used for the PCB motor design.


Altium Designer

Altium Designer is a comprehensive PCB design software widely used by engineers and designers for various tasks, including PCB motor design. It offers features such as schematic capture, PCB layout, and 3D visualization. Additionally, Altium Designer includes a vast library of parts, including motors, for easy integration into designs.

One of Altium Designer’s key strengths is its simulation capabilities, which encompass temperature analysis, power integrity, and signal integrity. These simulation tools enable designers to assess and optimize their designs under different conditions.

Altium Designer stands out for its user-friendly interface, supported by tutorials and resources to assist both novice and experienced users. Furthermore, it facilitates collaboration through cloud-based teamwork features, allowing multiple team members to work on the same design simultaneously.

ANSYS Maxwell is a specialized electromagnetic simulation software tailored for designing motors and other electromagnetic devices. It offers features such as heat analysis, circuit modeling, and 2D and 3D electromagnetic field simulation. The software provides a comprehensive library of materials and components, including coils and magnetic materials, for easy incorporation into designs.

The precision of ANSYS Maxwell is highlighted through its finite element analysis (FEA), enabling accurate simulation of motor operation under various conditions. Designers can optimize their designs to enhance effectiveness and performance accordingly.

Customization options within ANSYS Maxwell allow designers to tailor the software to their specific requirements using tools like user-defined functions and macros. Moreover, it seamlessly integrates with other ANSYS products such as ANSYS Mechanical and ANSYS Fluent for a more comprehensive analysis.


Infolytica Motor Solve

Infolytica MotorSolve is a specialized motor design software offering features for creation and analysis of motors. It includes tools for optimization, temperature analysis, and 2D and 3D electromagnetic field modeling. Similar to other software, Infolytica MotorSolve provides a vast library of materials and components for easy integration into designs.

The user-friendly interface of Infolytica MotorSolve makes it accessible to designers of all levels, supported by tutorials and resources. Optimization tools within the software enable designers to enhance designs for optimal performance.

Furthermore, integrating Infolytica MotorSolve with other Infolytica products like MagNet and ElecNet allows for a more comprehensive analysis. The software also offers connectivity with MATLAB and Simulink, as well as other third-party applications.



MATLAB/Simulink is a widely-used software package for modeling, simulating, and analyzing dynamic systems such as motors. It offers capabilities for signal processing, control system design, system modeling, simulation, and analysis. Additionally, MATLAB/Simulink provides a comprehensive library of building blocks and models for easy integration into designs.


Construction of PCB Motors

PCB motors, which are miniature electric motors integrated onto printed circuit boards, play a vital role in applications where compactness, lightness, and efficacy are paramount. Consequently, the design of a PCB motor encompasses several crucial components. Here are the fundamental elements essential for PCB motor construction:



The stator, a stationary component, contains wire coils responsible for generating the magnetic field. Often integrated into the printed circuit board, the stator consists of one or more wire coils wound around a central core. The specific configuration of coils and winding layout depends on the motor’s design and intended application.



The rotating part of the motor, known as the rotor, comprises permanent magnets or other magnetic elements that interact with the magnetic field produced by the stator. Typically mounted on a shaft supported by bearings, the rotor’s configuration, including the number and arrangement of magnets, varies based on the motor’s design and application requirements.



To facilitate smooth rotation of the rotor shaft, bearings provide support. In PCB motors, these bearings are typically small and precision-engineered for high-speed, low-friction operation. The choice of bearing type depends on the specific motor design and application demands.



While the rotor rotates, the commutator alters the direction of current flowing through the stator coils. Although not mandatory for PCB motors due to the ability to regulate current direction electrically using an H-bridge circuit, some PCB motor designs might still incorporate a commutator for convenience or other considerations.



To summarize, the PCB motor design entails numerous intricate and iterative processes, spanning from requirement specification to manufacturing and integration. Designers face challenges in ensuring that the constructed motor meets both functional requirements and physical constraints. This involves careful consideration of parameters such as magnetic, thermal, and mechanical design aspects. Despite the complexities involved, PCB motors offer significant benefits when approached with adequate consideration and strategic planning.
