  • Slide 3
  • 3 Length Motion Motors Motor Options 1. Series Motor with Brushes 2. Brushless DC Servo Motor 3. Brushless AC Servo Motor
  • Slide 4
  • 4 Series Motor with Brushes Advantages + Lower cost Move platform quickly Disadvantages - Less dependable (Brush failure) Difficult to control Linear encoder needed to determine position
  • Slide 5
  • 5 Brushless DC Motor Advantages + High starting torque Closed loop control Smooth operation High resolution Disadvantages - Made for large scale applications Expensive power supply More costly than conventional motors
  • Slide 6
  • 6 Brushless AC Servo Motor Advantages + -High starting torque -High resolution -Smooth operation -Highly recommended for similar applications -Easily controlled Disadvantages - -High Cost
  • Slide 7
  • 7 Drive Assembly Rack and Pinion Advantages + Low Profile Safety Low Cost Dependable Disadvantages - Binding & torque considerations
  • Slide 8
  • 8 Length Rail System Rail Options 1. Angle Aluminum 2. DualVee Linear Systems 3. Shaft and Rollers
  • Slide 9
  • 9 Aluminum Angle Advantages + Low Cost Easy to Install Disadvantages - No Vertical Constraint Dependent Upon Flume Rail Straightness
  • Slide 10
  • 10 DualVee Advantages + Vertical & Horizontal Constraint Independent of Flume Rail Package Deal Disadvantages - Complicated Installation High Cost
  • Slide 11
  • 11 Shaft and Rollers Advantages + Vertical and Horizontal Constraint Same Performance, Lower Cost Independent of Flume Rail Disadvantages - Some In-House Manufacturing
  • Slide 12
  • 12 Platform Design Constraints: Mounting Area Proximity of Water Accident Safeguards Easy Mounting & Removal Cantilevering Concerns Square Tube Concepts: Planar Design Hook Design Gantry Style
  • Slide 13
  • 13 Platform Design Hook DesignPlanar Design Support Rail StyleSupport Rail Style (T-channel)
  • Slide 14
  • 14 Platform Design Gantry Style Support Rail Style (C-channel) Features: Platform Elevated from Water Motor & Shaft Easily Accessible Restrained Vertically & Horizontally Easily Mounted & Removed from Flume Sides Guards Prevent Accidental Injury (Plexi-glass Window)
  • Slide 15
  • 15 Width & Depth Motion Velmex Slides Advantages High Accuracy Preassembled Motor Control Package Easy Installation (plug & play) Optional Way-Covers Disadvantages Slow Travel
