In Developing countries like our's we do encounter very frequest Mains power supply failures. This becomes a serious problem when the supply fails while we are cutting a big file.If power fails we have to start everything from the begining. I suppose a battery based inverter suppy would be the best option. Please comment. |

The MechMate has the following main power consumers
1. Control computer
2. Stepper motor power supply (300 to 500VA)
3. Router or spindle (1800VA router to 4000VA spindle)
Therefore you need about a 3000VA to 5000VA UPS (3kW to 5kW) if you want to keep everything going. There is not much sense in only keeping the computer going because the machine will loose its position.
A battery system of this size will be huge. |

Use a 5kW Electic motor...
to drive a heavy flywheel...
to drive a generator....
to drive the MechMate.
If your supply company trips, it triggers the "pause" in Mach3. The flywheel gives you time for the router/spindle to come to a controlled stop.
This is all theory - I have never heard of anyone that has actually done it for a MechMate.
However, it is standard practice for communications systems on mountain tops out here. There they have the motor/flywheel/generators running with 2 tonne flywheels - when the mains power is lost, a diesel/gen starts up and feeds the motor again. |
