In this project, a major amusement park required a reliable drive solution for its iconic Swing Arm ride. Operating such a facility poses unique engineering challenges:
High Starting Torque: The swing arm has massive mechanical inertia, requiring the drive to provide high torque at low frequencies to initiate motion smoothly.
Extreme Thermal Load: Located in a tropical region, the equipment is exposed to direct sunlight with ambient temperatures often exceeding 45°C, demanding superior heat dissipation.
Absolute Safety: Passenger comfort and safety are paramount. Any jerky movement or sudden stopping could lead to mechanical wear or safety risks.
Janson Controls deployed the FC100P Series VFD to manage the heavy-duty swing arm, leveraging several core technical advantages:
Superior Torque Delivery: Utilizing advanced sensorless vector control, the FC100P provides 150%-180% starting torque, ensuring the arm accelerates effortlessly from a standstill.
Smooth S-Curve Ramps: The programmable S-curve acceleration and deceleration profiles eliminate mechanical shock, providing a "silk-smooth" experience for passengers while reducing gear stress.
"Tropicalized" Design: Engineered for harsh environments, the FC100P features an independent cooling duct and thrives in unstable grids (±15% voltage fluctuation), making it ideal for the Middle East and Southeast Asian markets.
Dynamic Braking Mastery: Integrated braking control handles the regenerative energy produced during the swing's downward motion, maintaining precise speed control throughout the ride cycle.
Since installation, the FC100P has achieved 100% uptime even during peak summer seasons.
Maintenance Savings: Mechanical wear on the gears has been reduced by 30% due to the smooth torque control.
Passenger Experience: The park has reported increased visitor satisfaction due to the improved smoothness of the ride.
Energy Efficiency: Optimized motor control has resulted in a measurable reduction in daily power consumption.
