CEM-201  DC Motor Technology Trainer

  • This trainer is designed to meet the  operation training of various DC electric machines, covering 
     DC series motor, DC shunt motor, DC  compound generator and related testing panels.
  • 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.
