Motor electronic controller layout design principles

  1. Functional principle: The layout design must first meet the functional requirements of the controller to ensure that the function realization of each component is not affected.
  2. Reliability principle: The selection and layout of each component should ensure the stability and reliability of the controller and avoid controller performance degradation or failure due to unreasonable layout.
  3. Efficiency principle: On the premise of satisfying functions and reliability, the efficiency of layout design should be improved as much as possible and manufacturing costs should be reduced.
  4. Maintenance principle: The layout design should consider the convenience of maintenance and repair, making it convenient for operators to perform daily maintenance and troubleshooting.
  5. Safety principles: Layout design should comply with relevant safety regulations to ensure the safety performance of the controller under normal operation and abnormal conditions.

Key points in layout design of motor electronic controller

Component layout

Reasonable layout of components based on circuit functions and current and voltage levels requires consideration of factors such as heat dissipation, electromagnetic compatibility, and signal transmission distance.

Power module layout

The layout of the power module should be as close as possible to the electrical load to reduce the length of the power cord and reduce losses. At the same time, the heat dissipation and isolation issues of the power supply should be considered.

circuit protection

Circuit protection should be fully considered in layout design, such as overload protection, short circuit protection, overvoltage protection, etc. Appropriate protection circuitry can enhance the safety and reliability of the controller.

signal processing

For input and output signals, the direction of the signal lines and the location of the interface must be reasonably arranged to ensure stable transmission and processing of signals.

Thermal design

According to the power consumption of the components and the ambient temperature, a reasonable heat dissipation design is carried out to ensure the stable operation of the controller.

electromagnetic compatibility

The influence of electromagnetic interference should be considered during layout design, and corresponding measures should be taken to improve the electromagnetic compatibility performance of the controller.

Assembly and repair

Consider the convenience of assembly and maintenance, and rationally arrange the location and disassembly of each component to improve production efficiency and maintenance quality.

Standardization and modularization

The adoption of standardized and modular design ideas facilitates the interchange and combination of controllers for different types of motors, while reducing production costs.

Motor electronic controller layout design optimization method


Use professional software to simulate the layout design, predict the performance and reliability of the controller, and discover and solve problems in advance.


Optimization algorithms such as genetic algorithm and particle swarm algorithm are used to optimize the layout design to find the optimal solution.

Modular design

The controller is divided into several modules, each module has specific functions to facilitate assembly and maintenance.

Automatic routing

Use automatic wiring software to route circuit boards to improve the efficiency and accuracy of wiring.

Parametric design

For commonly used components and parts, a parametric model is established to facilitate quick adjustment of layout design.

Reliability assessment

Conduct a reliability assessment of the layout design, including environmental adaptability, mechanical strength, electromagnetic compatibility, etc., to ensure the stability and reliability of the controller.

Cost analysis

Conduct detailed analysis of the cost of layout design, including material cost, manufacturing cost, maintenance cost, etc., to achieve cost control and optimization.

Iteration and optimization

In the preliminary design and detailed design stages, iterative optimization is continuously carried out to make the layout design more reasonable and perfect.

in conclusion

The layout design of the motor electronic controller is a key factor related to the performance, reliability, cost and maintainability of the controller. By following certain design principles and considering various design points, and adopting appropriate optimization methods, the quality and competitiveness of motor electronic controllers can be greatly improved.
