I can only echo Richards comments or you may end up with frying chips !
There is a strong possibility with a derailment that the motor chassis block could come in contact with the running rails. Also, there are a few loco's that have a completely metal chassis, such as the NS OHE.
For the sake of the insulated motor backplate it's not IMHO worth the small cost saving - BTW there are actually about five different types of backplate.
Having said that, although the older three-pole motor, regarded by many as poor actually runs very well with a well set up decent decoder - as long as everything is clean, especially the commutator segment gaps & free running.
Another trick I've found with these older locos is (only if you tend to "pull" in one direction though) is to swop the wheels around on the motor bogie so that the two traction tyres are on the "rear" axel. Make the gear train mesh better & increases the haulage capacity.
