Polarization test
Before testing, make sure that the electrical and mechanical
protection of the linear motor system is well configured!
There is one regular way of testing the polarization. Some servo
amplifiers can operate in an in moment service mode. By means of
regulating an external resolver manually, it can be determined whether
the motor's direction of running conforms the resolver's sense of
rotation. If so, the motor is well connected. If not, two phases of the
power cable – phase 1 and 3 – must be changed.
Internally all ironless linear motors are equally wired and connected, so
one test satisfies to find out the polarization of a motor ruler
combination. If more axes are constructed in a similar way the
polarization will be equal.
