CEM-301 AC & DC Motor Technology Trainer

Description

• 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.
