CLIENT BACKGROUND:
A company in the aviation industry operates a large vessel designed for ocean navigation. This vessel is equipped with radar systems that require a robust motor to ensure reliable rotation under challenging environmental conditions.
TECHNICAL REQUIREMENT:
Motor:
Custom Rotary Stepper MotorSpecial Features:
Anti-corrosive Parylene coatingEngineering expertise to reconfigure airgap while maintaining very tight tolerances
CHALLENGE:
The original motors used in the radar system exhibited significant rust and corrosion due to exposure to high humidity and salty environments. The client sought a solution that would eliminate rust, rather than relying solely on an IP65-rated motor.
CUSTOM SOLUTION:
The custom motor was designed to withstand the extreme environmental conditions of high humidity and salinity, ensuring long-term corrosion resistance. To achieve this, we applied a specialized anti-corrosive Parylene coating to both the motor’s rotor and stator. Since stepper motors typically have a very small air gap between these components, we increased the gap slightly while maintaining tight tolerances. This adjustment allowed for an even coating of the rotor and stator without affecting the motor’s overall integrity.
RESULTS:
The custom motor solution delivered significant operational improvements, enhancing both efficiency and cost-effectiveness. Key results included:
EFFICIENCY IMPROVEMENTS
Enhanced motor reliability in harsh marine conditions
PRODUCTIVITY GAINS
Consistent performance without the need for frequent replacements
OPERATIONAL COST SAVINGS
Parylene coating costs a fraction of fully IP65-rated motors
MAINTENANCE REDUCTION
25% reduction in maintenance costs and consistent operational uptime
