Make Your Shredder Single-Phase With Reverse Mode
This How-To will show you the way to convert your three phase single direction shredder into a new single phase-reverse function shredder. Which means that you would be able to plug it in anyplace you go. This is quite usefull if you like to go around with your shredder or if your workspace has only single-phase electricity.
The reverse function is quite cool when your shredder gets jammed. —
Step 1 - Gather your material
- Motor (this case is a threephase 1.5kW)
- VFD (according to the motor)
- Cables (different colors helps to identify ground, neutro and phase)
- 2 position switch (16A)
- 3 position switch (16A)
- Emergency button (16A)
- Magneto-thermal switch (16A P+N type C or D)
- Plug (16A)
- Conection stripe
- Electronics box
Step 2 - Choose your VFD
This time I have used a VFD Delta 1.5kW singlephase but you can use any VFD that fits your needs.
Important that you use one able to handle the watts of your motor or above, the volts input of your motor and important the VFD uses single-phase input.
Step 3 - Gather your tools
- Soldering station
- Wire cutter
Step 4 - Rewire your motor
Step 5 - Graphic circuit diagram
SAFETY TIP: Try to wire them in the conection stripe in one side all your line conections and in the other side neutral conections then put in the middle all your grounds together. This would avoid more likely short-circuits in your machine.
Step 6 - Set up your VFD
There are a few parameters you should set up before turning on your machine to make it run safely and smooth. These parameters have a lot to do with your motor, so get your motor specs before starting. (These are engraved on a little metal sheet in your motor)
I would recommend you to find your VFD manual for this stage.
In this case I will show you the parameters for a DELTA VFD015EL21A and a 1.5kW 3phase motor.
Step 7 - Time to shred!
