电磁转矩电动机广泛应用于电液伺服阀。它们有助于扭矩转换成比例的控制电流。-The electromagnetic torque motors are widely used in electrohydraulic servovalves. They serve to convert the control current into a proportional torque. For more details about this issue, please refer to my book:

通过simulink建立电磁阀模型，通过pwm控制，控制电磁阀的开闭(The model of solenoid valve is established by Simulink, and the opening and closing of solenoid valve are controlled by PWM control)
