Introducing Motor Faults Pracbox
We have developed a new product called Motor Faults Pracbox to assess and train your learner’s in single and three-phase induction motors and fault finding them.
Here’s a video to give you a brief overview about the Motor Faults Pracbox
Here are the main points about the Motor Faults Pracbox
There are two sides to the Motor Faults Pracbox
- Three Phase
- Single Phase
Both motors work at Extra Low Voltage (ELV) that means the supply voltage will be less than 50V AC.
In the middle of both sides, there is a touchscreen display for you to choose which types of faults you want to add to the motors. The fault system requires a 5V 4A power supply to operate. The motors and fault system are not entirely dependent on each other, which means that you can operate the motors without the fault system.
Where can you use the Motor Faults Pracbox
As mentioned earlier, you don’t need the power supply the 5V power supply to run the two motors. If you’re assessing or teaching your learners UEENEEG102A about star and delta configuration or if you’re assessing or teaching them UEENEEG006A that has three-phase and single-phase motors, you don’t need the fault system. All you need is an Extra Low Voltage (ELV) AC power supply.
However, when it comes to UEENEEG108A, when you’re assessing them on fault-finding, you will need that 5V supply to operate the fault system.
Some of the Units of Competency that you can assess and train your learners in are:
- UEENEEG102A Solve problems in low voltage a.c. circuits
- UEEEL0020 Solve problems in low voltage a.c. circuits
- UEENEEG006A Solve problems in single and three-phase low voltage machines
- UEEEL0024 Test and connect alternating current (a.c.) rotating machines
- UEENEEG108A Trouble-shoot and repair faults in low voltage electrical apparatus and circuits
- UEEEL0014 Isolate, test and troubleshoot low voltage electrical circuits
Three-phase Induction Motor
The three-phase induction motor in the Motor Faults Pracbox is rated at 24V or 41.5V, depending on the way you connect them. You can connect the motor in Star or Delta configuration. The stall current is around 1.1A when the motor is in Delta configuration.
As you can see, the winding layout on the panel matched the industry so that when you teach your learners about them, they’ll be able to relate it to what they see out there.
The torque for this motor is low enough that you can stop the motor by hand to understand what stalling is but strong enough so that you can tell the difference between Star and Delta configuration.
Single Phase Induction motor
The single-phase motor needs 41.5V to operate and has a stall current of around 0.7A. This motor can be connected in the following configurations
- Cap Start motor
- Cap Run motor or Permanently Split Cap motor
- Cap Start/Cap Run Motor
The start capacitor is a 22uF capacitor, and the run capacitor is a 7uF capacitor. Neither one have a bleed resistor so that you can do capacitance test without any problems. However, this means that they will hold a charge after the motor has been disconnected unless you discharge them manually or through the motor.
Again, the torque for this motor is low enough that you can stop the motor by hand to understand what stalling is but strong enough so that you can tell the difference between various configurations of a single-phase motor.
The Fault system
We have developed a unique fault system that has three different levels of fault sets. Both single and three-phase fault systems follow the same concept.
Fault 1 to 10 will induce one fault in the motor, Faults 11 to 20 will induce two faults, and Faults 21 to 30 will induce three faults. The purpose of this concept is to provide more challenge for the learners and gamify the equipment for assessments and learning. Challenging the learners is the best way to grow their knowledge, understanding and confidence and to prove their competence.
We have gone through rigorous testing to ensure that the Fault sets don’t induce faults that will generate another unintended fault, which will not only create confusion but put the trainer or the assessor in a stressful situation.
The Motor Faults Pracbox can be a great assessment and training resource for your learners. It covers so many units that it gives you fantastic return on your investment.
It’s the easiest way to train your learners in a controlled environment and assess their understanding, by giving them the opportunity to challenge themselves and prove their competence.
