Reference list • Mechatronics Handbook ch. 20 • http://www.pneumaticpart.com/news/solenoid-valve-work.html • http://en.wikipedia.org/wiki/Solenoid_valve • http://en.wikipedia.org/wiki/Solenoid • http://www.societyofrobots.com/actuators_solenoids.shtml ECE5320 Mechatronics. Assignment#1 Survey on sensors and actuators

  4. To explore further • http://www.detroitcoil.com/PAGES/What%20Is%20A%20Solenoid.pdf • http://www.tai-shing.com.tw/technical/solenoid.htm • http://www.tlv.com/global/TI/steam-theory/types-of-valves.html ECE5320 Mechatronics. Assignment#1 Survey on sensors and actuators

  5. Major applications • Sprinkler Valves • Irrigation Control • Circuit Breakers • Domestic Appliances (washers/dishwashers) • Paintball Guns • Pneumatic Systems • Hydraulic Systems ECE5320 Mechatronics. Assignment#1 Survey on sensors and actuators

  6. Basic Working Principle Made of four simple components • Solenoid • Valve • Seals • Electrical Interfaces http://www.pneumaticpart.com/news/solenoid-valve-work.html ECE5320 Mechatronics. Assignment#1 Survey on sensors and actuators

  7. Basic Working Principle Solenoid: an actuator that converts electrical energy into mechanical energy using a charged solenoid coil to move the core plunger in or out. Mechatronis Handbook ch. 20 ECE5320 Mechatronics. Assignment#1 Survey on sensors and actuators

  8. Basic Working Principle Solenoid: When the solenoid coils are energized by an input voltage, the plunger is moved by the force equation: F = βLI where β = μ(N/L)I, μ is the permeability of the material, N is the number of windings, L is the length of the plunger, and I is the current through the windings. ECE5320 Mechatronics. Assignment#1 Survey on sensors and actuators

  9. Basic Working Principle Solenoid: Two types of solenoids exist: pull and push. These work based on the magnetic force produced by the coil around the plunger. By reversing the field direction, the plunger moves in the opposite direction. Mechatronis Handbook ch. 20 ECE5320 Mechatronics. Assignment#1 Survey on sensors and actuators

  10. Basic Working Principle Valve: made of an inlet (2), outlet (3), and some form of regulator (1). Valves regulate the flow of the controlled substance from the inlet to the outlet by controlling the size of the opening. http://www.pneumaticpart.com/news/solenoid-valve-work.html ECE5320 Mechatronics. Assignment#1 Survey on sensors and actuators

  11. Basic Working Principle Seals: “A device that helps prevent leakage, contain pressure, or exclude contamination.” (Wikipedia) These can be made of many different types of material including metal, rubber, and plastic. ECE5320 Mechatronics. Assignment#1 Survey on sensors and actuators

  12. Basic Working Principle Electrical Interfacing: To be activated the solenoid coils must be charged with an input voltage and current from an external controller. Operating voltages vary depending on the size of the coil needed for output force requirements. ECE5320 Mechatronics. Assignment#1 Survey on sensors and actuators
