I think i burned my motor up .

I see. So that one sounds even better.

Yes it does . Besides the upgraded rotor wont fit with out the larger bearing .

I talked to a novak tech today . I told him what i told you & he suggested the same thing. But i noticed there is a faint smell coming from the motor. when i told him this he said it sounds like it maybe more than the rotor thats messed up . so im not going to buy a rotor kit , only to find out something elese is wrong . so i guess im going to have to buy a new motor .

Is the smell simply "that new motor" smell? Even when not new, the varnish does have a distinctive odor.

Coil windings are so short that they have very little DC resistance, so getting a reading with an ohmmeter is all but impossible. However, you could build a simple oscillator (555 timer based) running at ~20kHz. Add a little "current amplifier" to the output (1A max), and hook each motor lead to it with a precision 1ohm resistor in series. The voltage drop on the resistor should be equal on all phases.

In all honesty it kind of has that burnt motor smell . But it's not a very stronge smell .

I demagged my HV4.5 5mm shafted rotor. I put the orginal rotor back in and it worked fine. The motor had a burned smell too. You can always send your motor to Novak with the demagged rotor installed and they will replace it with less than the cost of a new motor.
