2Y-Y-2△-△ connection four-speed motor switch control circuit
Source: InternetPublisher:常思一二 Keywords: Motor switch control circuit TI BSP Updated: 2020/03/25
The circuit is shown in Figure 3-119. Through the combination switch SA, the wiring of △, 2△, Y and 2Y of the stator winding is realized
[corresponding to the motor speed n1, bamboo 2, n3, 74 respectively ( TI l <n2 <n3 <Ti4)].
