Case Study
Ensuring Life-Saving Efficiency with
a Custom Rotary Motor Solution
CLIENT BACKGROUND:
This client specializes in manufacturing life-supporting ventilators, which played a critical role in healthcare settings during the COVID-19 pandemic. The ventilators required a custom rotary motor that would meet stringent performance standards while achieving rapid production to meet urgent demand.
TECHNICAL REQUIREMENT:
Motor Type: Rotary Stepper Motor
Special Features: Consistent detent torque, Custom connector and output shaft, Optimized concentricity adjustments for torque reliability
CHALLENGE:
At the onset of COVID-19 in 2020, the client required a motor with reliable, consistent detent torque for their ventilators. The motor needed to be certified with their existing setup, as time was too short to qualify a new supplier. DINGS’ also faced the challenge of producing over 100,000 units within three months to meet urgent healthcare demands.
Mechanical Adjustments: Custom output shaft and bespoke connector/wiring to fit seamlessly with the client’s driver board.
Electrical Modifications: Tailored windings to align precisely with driver specifications.
Precision Engineering: Enhanced tolerances for stator ID, rotor OD, and bearing mounting, ensuring uniform detent torque across all production batches.
CUSTOM SOLUTION:
Through focused collaboration, we developed a highly customized rotary motor to meet the client’s needs for torque consistency and integration.
Unique Customizations included:
RESULTS:
The custom rotary motor solution provided significant operational and cost-saving benefits:
ZERO WASTE
Eliminated motor scrapping
due to detent torque variation, reducing motor costs by more
than 50%
SEAMLESS INTEGRATION
The motor’s integrated connector and custom output shaft provided flawless compatibility with the client’s assembly, reducing production time
RELIABILITY UNDER PRESSURE
Delivered 100,000+ motors within three months, ensuring ventilators reached healthcare facilities
in time to support urgent
medical needs
