Definitions

  • the present invention is mainly related to an electromagnetic actuating device installed with a driving coil having driving and holding taps and the common connector, wherein the driving coil having a driving tap and a common connector to appear lower impedance is operatively controlled by the switching device to be electrified for excitation, then after actuation, said driving coil having a holding tap and a common connector is further operatively controlled by the switching device to be switched to appear higher impedance to hold electrification for excitation, thus reducing currents passing through the driving coil while required operating characteristics of the electrified electromagnetic actuating device to electromagnetic actuation are still satisfied thereby saving electric power and reducing heat loss in the driving coil of the electromagnetic actuating device.
  • the coil electrification status remains unchanged when the electrification status is actuated and held, i.e. the required excited currents for actuating and holding electrification are the same, therefore it has disadvantages of high heat loss and wasting electric energy.
  • the present invention discloses an electromagnetic actuating device with the driving and holding tapped coil, wherein the driving coil of the electromagnetic actuating device having driving and holding taps and the common connector is operatively controlled by the switching device, wherein it includes applications for normal close or normal open type electromagnetic brakes, normal close or normal open type electromagnetic clutches, normal close or normal open type electromagnetic switches, normal close or normal open type electromagnetic relays, normal close or normal open type solenoid valves, etc.
  • the driving coil having driving tap and common connector to appear lower impedance being electrically actuated to produce a larger electromagnetic actuating force on the electromagnetic actuating device is operatively controlled by the switching device to be switched to appear relatively higher impedance thereby holding electrification for excitation thus reducing total current passing through the driving coil, while required operating characteristics of the electrified electromagnetic actuating device can still be satisfied thereby saving electric power and reducing heat loss in the driving coil of the electromagnetic actuating device.

  • the electromagnetic actuating device (102) with the driving coil (102') having a driving tap (T1), a holding tap (T2) and a common connector (T0) is operatively controlled by the switching device (101) to switch the driving coil (102') from relatively lower impedance being electrically actuated for excitation to higher impedance being holding electrification for excitation, wherein the switching methods include:
  • Said individual driving coil (102') can be optionally constituted by conducting wires of the same or different material or the same or different conduction cross-section areas, or constituted by windings with the same or different numbers of coils.
  • Said driving coil (102') can be constituted by the following:
  • the driving coil (102') of the electromagnetic actuating device having a driving tap (T1) and a holding tap (T2) and a common tap (T0) is switched from the relatively lower impedance being electrically actuated for excitation to higher impedance being holding electrification for excitation during start operation; wherein the switching method is further shown in Fig.
  • FIG. 7 which is a circuit-block schematic view showing that the electromagnetic actuating device is installed with a position detector device to operatively control the driving coil; wherein the position detector device (105) is installed at a stable position after relative actuation between the rotor and the stator of the electromagnetic actuating device (102) or at a selected position in the stroke of actuation, so that the electromagnetic actuating device at relatively lower impedance being electrified to the selected position is through the position detector device (105) to directly switch the driving coil (102') of said electromagnetic actuating device (102) from relatively lower impedance being electrically actuated for excitation to higher impedance being holding electrification for excitation; or the driving coil (102') is operatively controlled by the switching device (101) being operatively controlled by the position detector device (105) to be switched from relatively lower impedance being electrically actuated for excitation to higher impedance being holding electrification for excitation;
  • the position detector device (105) can be constituted by pressure sensing type electromechanical switching devices or pressure-actuating spring leaf type switches, or can be constituted by optical, electromagnetic inducing type, capacitive inducing type or other conventional position sensing devices, wherein this device can be optionally installed or not installed as required.
  • the driving coil (102') of the electromagnetic actuating device having a driving tap (T1) and a holding tap (T2) and a common tap (T0) is switched from relatively lower impedance being electrically actuated for excitation to higher impedance being holding electrification for excitation during start operation; wherein the switching method is further shown in Fig. 8 which is a circuit schematic view of a DC power application example of the present invention showing that a charge/discharge capacitor (C1) being parallel connected between the holding tap (T2) and the driving tap (T1) is switched and cut-off power with a delay;
  • C1 charge/discharge capacitor
  • the electromagnetic actuating device with a driving coil (102') having a driving tap (T1), a holding tap (T2) and a common connector (T0) can be operatively controlled to allow the driving coil (102') installed in the electromagnetic actuating device (102) of relatively lower impedance to be electrically actuated for excitation so as to obtain the larger actuating power and response characteristics, then it is operatively controlled by the switching device (101) to be switched to appear relatively higher impedance thus holing electrification for excitation, thereby reducing total current passing through the driving coil (102'), while required operating characteristics of the electromagnetic actuating device (102) in electrification can still be satisfied by the electromagnetic effective force thereby saving electric power and reducing heat generation in the electromagnetic actuating device.
  • the invention also provides an electromagnetic actuating device with a driving coil having a driving tap, a holding tap and a common connector to provide a lower impedance being electrically actuated to produce a larger electromagnetic actuating force on the electromagnetic actuating device, then the driving coil is operatively controlled by the switching device to be switched to have the holding tap and the common connector provide a relatively higher impedance, thereby holding electrification for excitation, thus reducing the total current passing through the driving coil, while required operating characteristics of the electrified electromagnetic actuating device can still be satisfied, thereby saving electric power and reducing heat loss in the driving coil of the electromagnetic actuating device; it mainly comprises:
