The varnish will keep the individual wires together but would suggest wrapping a single layer of friction or electrical tape on the ends and not rely on just the varnish there. When the coils are powered they will shift a small amount and could rub against the motor case making short work of the varnish. Some liquid electrical tape can also provide a bit more bulk than the varnish for bared spots where the wrapping is mostly still good.

The center side portion where the shoe slides to hold the coil looks OK and there is no room for more tape there anyway but ends do need a bit. Any extra thickness added, make sure the inner armature side is no thicker than the rest of the coil and the whole coil end doesn't get pushed out as it is mounted. At the very end where the colored wire solders on a little bulk is OK but on the inner side, the end of the armature can hit any extra and rub.
