This system of task-specific, motor control-related training devices facilitates hands-on training in the operational principles, wiring, fault troubleshooting and application of industrial motor control devices commonly encountered in industry. Each device is self-contained, allowing for study by a student or small student group independently.

In practice, individual training workstations are designed to be used sequentially, from most basic to the most challenging. In this way multiple workstations are used simultaneously, accommodating a larger student groups.

Each individual training module includes a welded aluminum base assembly, steel support structure and enclosure, tslotted motor mounting rails and an applicable motor with sub-base. The primary mounting structure and motor can be removed from the base assembly and integrated with compatible mechanical and electrical products.

All wiring is accomplished through shielded banana-jack connections on the front panel face, rather than directly to individual components. A minimum of four fault switches, creating simulated common component and circuit faults, are provided with each device for use in troubleshooting. Supplemental components such as a motor loading device and a piloting switch module can be added to expand the system’s capabilities. Redundant safety features include an instructor fault switch, system circuit breaker with lock-out/tag-out, E-stop, internal redundant grounding, enclosure killswich, and more.
Welded tubular aluminum base assemblies, using 1-1/2" square, 1/8" wall aluminum tubing.
Aluminum t-slotted mounting rails, allowing for attachment of on-board tethered motor and connection to associated devices.
16-Gauge, formed-steel support structure, allowing for attachment to base assembly or integrated with other devices using mounting bench products.
16-Gauge, formed-steel primary electrical enclosure.
High-durability powder-coated surfaces throughout.
Powder-coated and silk-screened 1/8" aluminum front panel face.
Keyed instructor power switch (Rear of all devices).
On-board circuit breaker with provision for representative lock-out/tag-out.
System pilot light and large emergency stop switch.
Industrial-duty 56-frame motors as applicable for each device.
Internal electrical safety interlock system, de-energizing power when opening electrical enclosure.
DIN rail-type electrical components, where applicable.
Color-coded, shielded banana-jack receptacles for all motor leads and control components.
Permanent internal grounding (not dependent on student wiring).
Four instructor fault switches (rear of all devices).
Use of UL and CE certified electrical components throughout.
Allows for attachment to optional control and mechanical devices directly using optional electro-mechanical integration bench products.
