TTP Lab, a seasoned design consultancy specializing in multi-market product development—encompassing industrial, commercial, aerospace, communications, medical, and life sciences—has a long-standing reputation for prototyping and validating products before transferring them to designated manufacturers for mass production. Recently, TTP faced the challenge of developing a new diagnostic instrument prototype within an extremely tight timeline.
Key technical requirements for the instrument included:
• Precise positioning at specified speed and acceleration to the (next) designated sample station
• 12-degree sample rotation during loading, unloading, and reading cycles
• Reliability, low noise, and a compact form factor suitable for laboratory benchtop use
• Exceptional Cost-Performance Ratio: New drives offer optimal balance of performance and affordability
• Agile Response: Rapid validation of customer design concepts through iterative testing
• Rapid Prototyping: Accelerated translation of ideas into physical samples
• Robust Customization: Tailored solutions to meet unique application requirements
• Integrated Mechatronics: Motor-driver synergy simplifies system integration
• Comprehensive Product Portfolio: One-stop access to a full range of motion components
TTP partnered with SXEGL to develop a benchtop medical instrument requiring precise speed control and customized parameters. SXEGL provided a 42mm brushless DC motor with an integrated servo driver that met all specifications. After testing the sample hardware and software, TTP fully endorsed the motor-driver integrated solution.
As development progressed, TTP built a functional prototype: the motor drove sample rotation at the required speed and acceleration. SXEGL manufactured a coupling via 3D printing within days and programmed motion control logic into the IDEA driver. Following assembly, HKP tested the motion sequence, recorded a demonstration video, and delivered the motor to TTP for final integration. The IDEA motor’s flexibility allowed TTP to adjust programs or ports in real-time during testing.
While performance met expectations, the IDEA motor’s height posed an installation issue. Valuing the driver’s servo capabilities, TTP proposed converting it into a pluggable module for motherboard integration. SXEGL swiftly redesigned the driver into a modular form—retaining all functions while altering only the mounting method.
To optimize space and positioning accuracy, TTP customized the motor with a shorter shaft and higher-resolution encoder—standard capabilities in SXEGL’s customization portfolio. For thermal validation, TTP ordered motors with thermocouples embedded in the windings, and SXEGL delivered the customized prototypes promptly as always.
Outcome
The IDEA DC motor solution enabled TTP to accelerate prototype development from months to weeks, propelling the project to the next phase. Their collaborative problem-solving on electromechanical integration resulted in a functional prototype. TTP’s client was so satisfied with the validation that they directly ordered customized motors and driver modules from SXEGL, underscoring the partnership’s success in both technical innovation and commercial implementation.
