CEM-301 AC & DC Motor Technology Trainer

    DETAILS

      • This trainer is designed to meet the operation training of various electric machines, covering a wide
         range for electrical machine control technologies for both AC and DC motors and generators.
      • All motors and generators come with standard aluminium profile mounting base, coupling and foot 
         pad   for easy experimental combination via universal shaft couplings of  same height.
      • The frame adopts standard aluminum profile with modular experiment panel design, thus, making it 
         easily to build different experiment combination on the flexible two-layer structure. All the upper parts
         are removable including the experiment  module, power supply module and frame support.
      • All terminals are led out on printed composite panel with 4mm safety socket and connected by
         full sealing sheathed pluggable connector. The complete unit is movable with lockable truckles on
         bottom and available for training content extension by using other CHOIEO modular electrical units.
