CEM-301
AC & DC Motor Technology Trainer |
 

|
• 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. |
