MOTOR MAGNET UPGRADE AND INSTALLATION PAGE
Here is a typical Suydam Interurban Chassis of the 60's and 70's, with a high quality, but very inefficient and high current 5 Pole motor
Replacing the motor with a really powerful and smooth slow running, but efficient low current Coreless Instrument Can Motor would cost around $50.00. But there is a way of getting the same effect for only about a tenth of that cost!!!!
Lets head for the Kitchen and cook up a little experiment :)
Here we are showing the 1960's Suydam Motor Magnet strength by stacking some tall hot cereal boxes from the pantry and using a hammer as an iron support to hang the heaviest thing the magnet will hold from it
Which turns out to be a handy, but quite light, steel rule.
Which explains why the motor running current is high and the slow running power, so very limited.
Now we try the same experiment with a similar magnet size, but using the very latest high technology Neodymium magnets . . But now we find we can easily just hang the whole one pound hammer from the ruler instead. . .
The relative strength of the new new magnet is staggering!
In fact, this similar size replacement neodymium magnet can lift almost 24 Pounds!!!! A phenomenal amount of improvement in the motor's magnetic field strength.
And since the motor torque is directly proportional to the magnet field strength, just upgrading the magnet alone, simply and easily turns the old motor into the near equivalent of the $50.00 Can Motor, but WITH MUCH LESS SENSITIVITY TO OVERHEATING AND DCC/PULSE POWER that the more delicate coreless can motors can exhibit.
Here we can see such a new magnet together with a magnetically transmissive adaptor plate, made to fit exactly into the same size and position as the original magnet
Refitting the new magnet kit is as simple as loosening the end screw and switching the new magnet for the old.
