3 kW AC Servo Drive From a 4 Ton Stone Polisher – Isolation, Day 32

I scavenged a old 4 ton stone polisher machine for the best components and got off with a 3 kW AC servo motor + drive, 4+0.55 kW variable frequency drives. In this video I try to make the servo motor run despite missing a control panel that was gone from the machine. Teardown of the […]

Variac, Auto-, Vario- and Isolation Transformers – Isolation, Day 28

I give a short introduction to the differences between autotransformers, variable autotransformers and variable transformers. I show my collection of 7 variac transformer / variotransformer in the range from 1x260V @ 2A to 3x400V @ 25A along with a 3x400V 10kVA isolation transformer. 3x400V @ 13A Variac demonstration with data monitor: https://www.youtube.com/watch?v=PqeLLLZTBb8 You might wonder

Fuses In Power Electronics and Other Fuses – Isolation, Day 24

This video shows the different fuses, breakers, MCB, RCD, melting fuses and automatic fuses that I have. I started spring cleaning my work shop and I have come across so many components in various bins, boxes and drawers that I finally had some time to get it sorted and put together in groups. High Voltage

High Voltage Insulators – Isolation, Day 20

In this video I talk about some of the high voltage insulator items I have collected. Normal household 230/400VAC porcelain insulators with brass mounting hardware. Lineman clamping connectors to be operated by an insulated rod. From a large distribution transformer, there is some large brown 10 kVAC feed through high voltage insulators. Railway electrification system
