A component part of the DAC, #410 Motor Fundamentals Training System, this supporting device allows for the application of consistent, and measured loads to system motors in order to study the operating characteristics of different motor types while under load.

The device couples to all DAC motor trainers and motor control trainers using a connecting coupling and coupling guard assembly, which is provided.

When used in other electro-mechanical integration applications the device also supports the use and control of brake/clutch assembles, specialty single phase motors, and other DC and AC powered accessories.

A magnetic industrial tensioning brake provides intermittent or continuous resistance to the coupled motor trainer through a dedicated rheostat.
Welded tubular aluminum base assembly with rubber support and vibration isolating feet.
16-Gauge, formed-steel support structure facilitating mounting of controls at a convenient and ergonomically-appropriate position.
Provision for direct-mounting, without base assembly of frame on related DAC bench and workstation products, as well as on t-slotted electro-mechanical integration bench work surfaces.
1/8" Aluminum, powder-coated and silk-screened front panel face.
Panel-mounted Electrical and control devices including master instructor key switch, mater circuit breaker with provision for lock-out/tag-out, pilot light, emergency stop switch, system GFI, with single-phase utility outlets, DC load control rheostat with relay control contacts allowing external control, brake/clutch assembly DC controller with indicating potentiometer control, and relay control contacts allowing external control, specialty single phase motor connector with relay control contacts allowing external control, component-proprietary connecting sockets.
Full permanent internal grounding and cover removal safety interlock.
Industrial electro-magnetic tensioning brake with 3/4" connecting shafting, with steel and aluminum mounting assembly, and dedicated connection cord.
Coupling/Guard assembly, incorporating aluminum baseplate, polycarbonate guard, Lovejoy (JAW & Spider) coupling allowing for connection to related motor modules.
Packaging for shipment via motor freight.
