The rotary type electromagnetic actuator is often used in the electromagnetic mechanical components design such as RF switch, signal electromagnetic relay, etc. Technical index of this type of actuator focus on high requirements for conversion speed, action frequency, signal reliability and the minimum volume under certain power. In this paper, a new type of rotary electromagnetic actuator with permanent...
Valve actuator is a critical component of the electromagnetic valve in the pneumatic steering gear. By controlling the action and release of the actuator, the gas circuit can be switched, thus to control the attitude adjustment of the missile. The traditional actuator is solenoid structure. In order to satisfy the demand of saving energy, lowering the driving power of the coil and providing enough...
The problem of electromagnetic ray transmission on the medium interface is discussed on the basis of variational manner. With the help of introduction of several quantities, amplitude and phase variational representation are employed to analysis the electromagnetic distribution in the matrix. The matrix in the form of direct multiply can be transformed into transmission matrix with the series property...
