Feedback Instruments Ltd |
Feedback’s Mechanical Transmission Trainer provides a variety of fully working components to demonstrate belt, chain and gear transmissions and couplings that are fitted on a worktable, with full industrial safety features.
This system has been designed with the specific purpose of meeting the needs of education and training centres offering programmes for multi-skilling, cross-skilling, mechanical technician qualifications and apprenticeships. The trainer provides hands-on experience to allow students and trainees to set up different transmission systems and compare them in terms of underlying principles, ease of assembly, maintenance issues and operational characteristics.
For maximum flexibility, the system is based on a worktable design, which can be supplied as either a complete mobile trolley (with built-in equipment storage), or as a unit suitable for bench-top mounting. Rubber-faced castors are fitted to the strong and sturdy mobile trolley, allowing the Trainer to be moved easily between locations.
Note that the guards can be easily lifted away (without tools) from the worktable, to allow full access during transmission set-up. However, operation of the motor is not possible until the guards are replaced and closed.
A complete collection of exercises and solutions is supplied with each system. These exercises support the transmission trainers and include exercises for motor, vee belts/pulleys, chains/sprockets, timing belts/pulleys, gearboxes and gear sets, clutches and couplings. Starting at a basic level, these exercises build up in complexity with issues such as: alignment, tensioning and adjustment.
Question and answer papers are supplied to monitor student progress. A licence for the original purchaser to photocopy course material is included.
The Inverter Drive and Three-phase Electric Motor gives students a basic insight into Electrical Motor Control without having to go into complicated electrical theory. The Inverter Drive and Three Phase electric motor has been designed to expand the curriculum covered by the Mechanical Transmission System. It is now possible to control a 3-phase motor from a single phase electrical supply by varying the frequency of the electrical output from the inverter drive.
The inverter control box has ‘Forward’, ‘Reverse’ & ‘Stop’ switches, along with a speed control dial for ‘High’, ‘Medium’, ‘Slow’ or ‘Variable’ speed, that enables the motor to be set to run in either ‘Forward’ or ‘Reverse’ direction and in each direction can be set to run at ‘High’, ‘Medium’, ‘Slow’ or ‘Variable’ speed.
The High, Medium & Slow speeds can be pre-selected (at different values), when the variable speed position is selected a potentiometer is used to give infinitely variable speed (in either forward or reverse direction).
Selection and programming of speeds (frequencies) can be made either from the inverter panal direct or from the hand-held programmer, which comes with the system. On the front of the inverter is a digital display showing the various parameters set as well as readouts of the frequency, current draw, programming codes, error codes etc.
