    • (b) Description of the Prior Art:
  • Conventionally using two or above two electromagnetic actuators generating electromagnetic effect through electrical current excited coil, where each set of excitation coil usually actuates and sustains electrically actuated operation is presenting parallel state, where the excitation current required is larger is its drawback.
    • SUMMARY OF THE INVENTION
  • The present invention is a kind of switch device for the control of two or above two electromagnetic actuators, for driving coil such as electromagnetic brake, electromagnetic clutch, electromagnetic switch, electromagnetic relay, and electromagnetic valve, etc. to perform parallel actuation, so as to generate better electromagnetic actuation power, and through the control of switch device, take driving coil switch into serial connection to reduce the electrical current of driving coil, but still maintain the operation of electrical actuation in order to save electricity and reduce the heat generated by the electromagnetic actuator.
  • As after serial connection of excitation coil it is still required to maintain the electromagnetic actuator device presenting under the operation of electrical actuator, therefore the electromagnetic actuation device applicable to the present invention must have the characteristic of maintaining electrically actuating operation after the excitation coil switched to serial connection state.
    • BRIEF DESCRIPTION OF THE DRAWINGS

  • Two of the above electromagnetic actuator devices are used as preferred embodiment and described below:
  • Fig. 1 illustrates the circuit block chart of the present invention, essentially comprised of:
    • -- Switch device 101: mechanical or electrical switches, relay, electromagnetic switch or solid state switch component, operated by human power, or mechanical power, or fluid power, or electrical energy; using alternating or direct electrical current energy to deliver to excitation coils 102' and 112' of at least two electromagnetic actuators 102 and 112, or for cutting off electricity operation;
      Said switch device can be used for the operation of switching, so that the excitation coils of at least two electromagnetic actuators can be first to perform parallel actuation and then switched to serial connection state, and during serial connection the electromagnetic actuator still could maintain the operation of electrical actuation;
    • -- Electromagnetic actuators 102 and 112: consist of at least two electromagnetic brakes, electromagnetic clutches, electromagnetic switches, electromagnetic relays, and electromagnetic valves with AC or DC electrical power excitation coil, the electromagnetic actuators has the basic characteristic of sustaining of electrical actuating operation while the excitation coils 102' and 112' are in serial connection;
    • -- Capacitors 103 and 113: matched AC or DC capacitor or other storage and discharging component based on the specification of electromagnetic actuator, for assistance of excitation coils 102' and 112' of electromagnetic actuator in sustaining the stable operation when switch device 101 is switching between series or parallel connection to excitation coils 102' and 112'. Such capacitor can either be installed or not installed based on the need.
  • The operation of the embodiment of Fig. 1 is described as below:
    • If VA is the normal minimum actuation voltage of the excitation coil of electromagnetic actuators 102 and 112, VH is the holding voltage of normal minimum sustaining electrical actuating characteristics for electromagnetic actuators 102 and 112. If taking the two electromagnetic actuators 102 and 112 of the preferred embodiment in Fig. 1 installed with the excitation coil of the same excitation actuator as example, the suitable working conditions of the excitation coil of the electromagnetic actuator are: Minimum actuation voltage VA of the excitation coil < 2 x minimum electromagnetic actuation state holding voltage VH.
  • In the practical application, this electromagnetic actuator parallel actuation serial sustaining driving circuit, the two or above two electromagnetic actuators installed can be formed by the same or different electromagnetic actuators.
