Features:

This trainer 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 generator come with standard aluminium profile mounting base, coupling and foot pad for easy experimental combination via universal shaft couplings of same height

The frame adopt standard aluminum profile with modular experiment panel design, thus, making it easy to build different experiment combination on the flexible two-layer structure

All the upper parts removable including the experiment module, power supply module and frame support

All terminals led out on printed composite panel with 4mm safety socket and connected by full sealing sheathed pluggable connector

The complete unit movable with lockable truckles on bottom
