Three-phase motor controller is superior in performance. By small below introduction to the main circuit basic type
1. Three phase half controlled circuit in three phase half controlled circuit, the requirement of position sensor output signal for high level, a third cycle two-thirds cycle as the low level, and asked the difference between the sensor signal is also a third cycle. 2。 The characteristics of the three phase half controlled circuit simple. Utilization ratio is very low, but the motor ontology each winding electricity only a third time, the other two-thirds of the time in the off state, has not been fully utilized. 3。 All control circuit three-phase delta connection
