Torque motor single-phase speed regulation circuit 2
Source: InternetPublisher:刘德华河北分华 Keywords: Motor speed control circuit BSP Updated: 2020/02/12
The circuit is shown in Figure 3-175. The voltage regulator is connected between one phase and neutral line. It is suitable for torque motors with a rated voltage of 380V
.
Since the imbalance degree of this method is not as serious as that of the line method, the working condition of the motor is better. As long as
the working speed is not too high, negative torque will basically not occur, but the range of torque adjustment is narrower.
