Single-speed motor self-exciting electric braking circuit a

 The circuit is shown in Figure 3-151. The capacitor group in Figure 3-151 (a) is connected in a △ shape, which is suitable for motors with △ or Y-shaped connections ; the capacitor group in Figure 3-151 (b) is connected in a Y shape, and it is suitable for motors with
Y-shaped connections . . The capacitor adopts a △-shaped
connection method, which requires a small capacitance, but requires a high withstand voltage (above 600V). For motors
with different powers , please refer to Table 3-2 for the selection of C and R.
