9.5 Winding resistance
As the motor is star-connected, the easiest way to measure the
winding resistance is to measure across two phases. Measure at
the coil temperatures stated in the table below. It may be
necessary to let the motor cool off if it has been running or if it
was stopped because of short circuit or overload.
