How Motor Architecture Shapes Surgical Hand Tool Performance
Portescap’s new white paper highlights motor architecture as a pivotal early‑stage decision for surgical hand‑tool design. It breaks down four core architectures—slotted, slotless, brushless DC and core‑less brushed—showing how each influences torque density, vibration, speed range and thermal management. The analysis also contrasts direct‑drive versus geared configurations and stresses system‑level co‑design with OEMs to mitigate risk. By aligning motor choice with specific orthopedic or cranial applications, manufacturers can meet stringent clinical performance and reliability standards.
