A buddy gave me a worm/pinion right angle gearbox with an old Westinghouse 56C frame 3/4 hp 3 phase motor on it. The motor was fitted with a Dings model 60 brake. The brake mechanism was a giant ball of rust. With the help of an angle cutoff grinder I got it all loose. Now it's hanging from two wires. I intend to try to resurrect this motor. I have seen amazing results from derusting and judicious bead blasting, and the wiring looks fine. Internal wiring insulation is not cracked. The bearings are 6203Z which I have a stash of. I don't see any reason not to pursue fixing this motor.
The Dings instructions say (for a dual voltage coil - the motor can be wired 240/480) "Connect leads 2 and 4 to any two line leads (single or three phase) of same voltage and frequency as the brake."
To me, that means the two wires leading from the junction box out to the brake are jumpers to two of L1, L2 or L3 so I should just cut them off and cap them, making sure they can never connect to anything.
But I'm nervous about it. Does that sound right to you?
