From First Principles Thinking to Complete ODM Solutions Built Around Motor Expertise
In today’s global manufacturing industry, competitiveness is no longer achieved simply by adding more features. It comes from designing the machine and its power system as a complete solution.
Many product development processes begin with the mechanical structure. The motor is then selected to fit the available space, followed by the addition of controllers, gear reducers, or other mechanisms. When the power system is not considered from the beginning, this approach can lead to unnecessary mechanical complexity, more components, longer development and validation cycles, higher manufacturing costs, and reduced system reliability.
With 50 years of experience in motor development and manufacturing, Yen Shen Electric designs from the most fundamental element of the system—the power source. By combining motor technology with electronic control, mechanical design, and complete machine development capabilities, Yen Shen provides OEM customers with integrated ODM solutions designed to improve performance, reduce total cost, and support long-term reliability.
Key Takeaways
- Motor-Centered Design: We consider the motor and power architecture from the beginning of machine development rather than selecting a motor after the mechanical structure is complete.
- First Principles Thinking: We begin with the application’s actual torque, speed, load, operating conditions, and performance requirements.
- Integrated ODM Expertise: Yen Shen combines motor development, electronic control, mechanical integration, protection functions, prototype validation, and mass-production implementation.
- Lower Total Cost of Ownership: In suitable applications, direct-drive BLDC solutions can reduce component count, assembly time, maintenance requirements, and transmission losses.

First Principles Thinking: Returning to Fundamental Requirements
First Principles Thinking means breaking a problem down to its fundamental requirements and rebuilding the solution from the ground up. At Yen Shen, this means we do not begin by asking which off-the-shelf motor should be selected. We begin by asking:
- What torque does the application truly require?
- What operating speed and speed range are needed?
- How does the load change during operation?
- Does the application require continuous operation under harsh conditions?
- How can performance, reliability, and cost be optimized together?
Once these requirements are defined, the motor, controller, and mechanical structure can be designed and integrated accordingly. This approach helps reduce incorrect motor selection, repeated redesign, unnecessary testing, and additional development costs.
Designing from the Motor Core
The motor is a core part of many machines. It directly affects output performance, energy efficiency, processing quality, product service life, and system reliability.
However, when the motor is selected only after the mechanical structure has been completed, engineering teams may face insufficient torque, an unsuitable speed range, poor thermal performance, limited controller capability, and repeated mechanical modifications.
Yen Shen starts from the application requirements, defines the appropriate power architecture through motor design, and integrates the controller and mechanical system around the needs of the product. The result is not simply a collection of separately manufactured components, but a system in which the motor, controller, and mechanical structure are considered together.
System Optimization and Total Cost of Ownership
Traditional machines may use a power-transmission chain such as:
Motor → Pulley → Belt → Gear Reducer → Coupling → Working Mechanism
While this structure can achieve the required function, it may also increase material costs, assembly time, maintenance requirements, transmission losses, and mechanical wear points.
In suitable applications, the high efficiency, fast response, and precise control of BLDC motors make it possible to simplify the power architecture:
BLDC Motor → Working Mechanism
Depending on the application requirements, this approach can provide fewer components, lower BOM cost, simplified mechanical design, reduced assembly time, less mechanical wear, and improved energy efficiency.
True cost optimization is not simply about selecting the lowest-cost component. It is about reducing the Total Cost of Ownership across the entire product lifecycle.
Application Examples: Motor-Centered Design in Practice
Case 1 | Direct-Drive Drill Press
Traditional drill presses often use a fixed-speed motor with multi-step pulleys. Operators manually change the belt position to adjust spindle speed for different materials and applications, which can result in downtime, belt wear, and ongoing maintenance requirements.
By treating speed adjustment as a motor-control challenge, Yen Shen developed a direct-drive BLDC power system. Operators can adjust speed electronically, while the system reduces the need for belt adjustment and other mechanical transmission components.
The controller can also monitor motor current and speed variations and reduce output or stop operation when abnormal loading conditions are detected, helping protect the motor and equipment.

Case 2 | Lifting Equipment
Lifting equipment must maintain stable and safe operation under changing load conditions. Yen Shen integrates sensing, motor control, torque monitoring, and electronic braking to help the system respond to overload or abnormal operating conditions.
When abnormal conditions are detected, the system can reduce output or stop operation. Combined with electronic and mechanical braking functions where required, this can help reduce the risk of uncontrolled load dropping, minimize mechanical brake wear, and improve operating safety.

Intelligent Control and Electronic Protection
A high-performance motor requires an appropriate control system to realize its potential. Depending on the application, Yen Shen develops BLDC control solutions involving speed control, torque control, acceleration and deceleration optimization, closed-loop control, Hall sensor, encoder or sensorless control, and communication interface integration.
Reliability can also be supported through application-specific protection functions, including over-current, over-voltage, under-voltage, over-temperature, stall, and abnormal-startup protection.
