| • This trainer is designed to meet the operation training of various AC and DC motors, covering a wide |
| range for electrical machine control and drive technologies. |
| • 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. |
