b) Drive control without sensor (sensor-less):
- Direction of motor rotation (clockwise/counter clockwise) can also be defined without a sensor, if the controller has a sensor-
less option. It can be defined by pole reversal, which can be achieved by a change of two motor phase cables. Three phase
power connectors UVW are shown below in this Item. Position and rotation speed cannot be defined without a sensor.
- Sensor-less can be used for e.g. boats, airplanes and for applications that do not need a high torque at the start (applications
with propellers).
