Frog A24E motor stopping

[Matt Turner]

We have metal electric gates powered by 2x Frog A24E motors linked to a CAME ZLJ24 control board. Recently one of the gates has stopped moving. Having had a look at the board and motors, while the wiring is a bit of a mess, as far as I can tell everything is working correctly and power is being sent to the motor in question when commanded.

When an open/close signal is sent the motor starts to move, but almost immediately starts to sound laboured and then the gate stops moving after a couple of inches of movement. The gate swings freely when in manual release and I have tried greasing the motor arm etc and now the gate will move if I ‘assist’ it in the right direction, but as soon as I stop pushing, the gate stops.

The other gate moves without any issues.

We’ve been let down by two engineers now so I’d like to take a look at it myself, I’m suspecting the motor is on its way out or there’s a problem with the reduction gears causing the motor to stop. I’ve seen you can buy replacement electric motors online rather than replacing the whole frog unit, so one thought I’ve had is to swap the ‘good’ motor from the other gate to see if it’s just the electric motor that’s going out (if that’s possible) or swapping the cables over at the control board end to see if it’s a transformer issue.

If someone can suggest what the issue may be or another solution, that’d be great. Thanks.

Hi,

it may be a couple of things it could be the geometry of the gate that has been putting extra work on the motor slowly wearing down the motor to the point it can't work anymore.

or it could be a capacitor-related problem you could check this by switching the capacitors over from the good motor to the one that isn't working and see if that makes a difference and if it does it should just be ordering a new capacitor to get them back working.

Thanks.

Do the 24v motors use capacitors? I can’t see a reference to them in the manual.

My next step I thought I’d remove the link arm and see if the motor can run without being connected to the gate, but I suspect it won’t as it doesn’t when the gate has been manually released.

No, The 24v doesn't have capacitors.

it may still be the geometry but if you want you could send some photos that we could take a look at for you see if we can see anything that may have caused the issue.

if you could take photos of the motor and the gates and we will see if anything stands out to us.
