Maglev Train Demonstration Miren Relucio, Lucas McPhee, Grant Wallace

Overview ● Create a Maglev Train Demonstration ○ Electromagnets used to levitate cart ○ Sensors used to measure distance between cart and track ○ Lateral Movement in both directions ○ Buck converter used to control current delivered to electromagnets ○ Demonstrated through simulations

Cart/Track

Magnets/Sensors ● Magnets ○ 1”-8 x 3- ½ ” Bolt ○ 22 AWG Enameled Copper Wire ○ 2000 Turns ● Sensors ● VL6180X ○ Lidar sensor ● HC-SR04 with ATmega328PB Xplained Mini ○ Ultrasonic distance sensing ○ Converts time delay between transmission and reception of ultrasonic signal

Constraints ● Coronavirus ○ Did not have the equipment we needed ○ Lacked the ability to collaborate with group in person ○ Unable to complete a physical model due to no access to the lab ● Time ○ Stuck to original design for too long ○ Amount of time we had forced us to try to merge new design with existing Maglev demonstration ● Technical ○ Design requirements limited options (No liquid nitrogen) ○ Needed mobile power supply
