Hello cmw,

Unfortunately we don't have one in stock to measure. If we did I would be happy to give you the information you need. And the manufacture does not give us the size either.

Question: Electro-Magnet Brake On A Delta ...

pcrable

I picked up an older Delta Model 33-412 Industrial Radial Arm Saw. It used to be the saw in one of the home and lumber stores around here and someone bought it from them when the store went out of business. The guy never did anything with the saw since it required 3 phase power.

Anyhow... I have the saw running, but the elecro-magnet that engages the brake to stop the motor and blade from spinning isn't working. I try an Ohm meter on the 2 wires going into the magnet and it shows open.

The replacement parts only show the whole motor (over $4k) and not the sub-components such as the brake magnet.

Anyone have any ideas on how I can repair or replace just the magnet ?

Thanks,
--Phil

I looked at the parts breakdown for your radial arm saw and I see the same thing: only the complete motor is available and it is [I]expensive[/I]. Unless you want to start replacing major saw components, I don't think there is a fix. I know some of the older radial arm saws didn't have an electric braking system and the blade would just spin and spin for a long time until it stopped. [I]Be careful[/I] of course while it's spinning, but it's probably not going to hurt anything. You can always carefully put a block of wood on the side of the blade to slow it down.

So far, I have figured out that the magnetic coil is open (took it to a motor shop and they confirmed).

I've ordered the magnetic wire to rewind the coil myself and think I can do that part just fine.

I'm now trying to figure out the wiring and it seems almost like there is a relay missing. My understanding is that T11 and T12 from the motor basically provide power to operate the magnetic brake... as the motor spins, it generates AC power that then goes to a Bridge Rectifier that converts the AC to 110V DC to power the magnet and thereby slow the motor down.

The question I have is... what keeps the magnet from engaging when you turn the saw on ? Seems like there should be a normally closed relay in the loop that opens the circuit to the brake when you turn power on. Then when you turn the power off, the relay closes again and the power generated from T11 and T12 in the motor windings powers the brake magnet.

Any Ideas ?

I got a call from Delta Machinery and they were nice enough to walk me through a few questions and then explain how the electric brake works.

I had it backwards and thought that the magnet would engage the brake when the saw was shut off.

The way it is designed to work is that when the saw is turned on, the magnet turns on and pulls the brake pad away. When you turn the saw off, some springs push the brake pad and the saw slows down.

Thanks to Delta Machinery :-)
