No, it is a LOT more complicated. Usually the motors are 3-phase,
permanent magnet, but there can be other types.
It is common to have Hall sensors for commutation, but not all motors
have these sensors. There are several schemes
for orienting these sensors to the motor poles. The motors typically
have 8 poles, but some may have other pole counts.
Encoders have all sorts of combinations available, some have the
commutation tracks and some don't, etc. If the encoder has
the commutation signals, then the alignment of the encoder to the
motor's poles is critical. Also, some motors, such as Yaskawa,
Panasonic and Fanuc often have something proprietary about the
commutation or encoder signals.

So, not only is the connector totally NOT standard, the signals
themselves vary quite a bit.
