Motor Starter Compliance.

Zoomup

On an old machine that has two manual motor starters like that illustrated in the link, which modern regulations do they fail to meet please? The machine has two separate cutting disks for cutting double glazed unit frames. The cutting discs are large and dangerous.

The two motors are 2.5kW three phase induction motors.

The actual motor starter overloads are rated at 4 to 6 Amps approx.

    are there E-stops or interlocked guards ? - we have IR beams on something not quite like that so that when the beam is broken by a body part, power is removed and a DC brake applied. IF it is really needed in your case, in  the UK requires it to be assessed by someone familiar with the ways to met the PUWER and the machinery directive.

    No Mike there are no beams, but the rotating cutting discs have a mechanical cover that retracts when the cutting process is progress. I was more concerned with the starter. It seems to be totally manual in operation. There is no D.C. braking. The cutting discs run on for over half a minute when the motor is turned off.

    A bit like the arrangement on a modern hand-held circular saw or a chop saw?

    Yep, just the same, and the machine has air lines presumably to operate the various gadgets.

    What do you think about the use of the type of mechanical motor starter illustrated above?

    Is it the lack of a (d.c.) braking system you're worried about? I'm not the best person to ask about machine safety, but my gut reaction would be that if the blade is guarded in pretty much the same way it is in other modern tools, then the fact that it keeps turning for a while probably isn't a worry.
