  • Electrical actuator
    Patent number: 5682129
    Abstract: An electrical actuator comprises a first actuator body (1) and a second actuator body (3). The first actuator body comprises two diametrically opposed magnetic poles (N) and (S). The second actuator body is made of a soft-magnetic material and comprises three inwardly directed radial teeth (19, 20 and 21). In order to obtain a maximal ratio between the delivered torque and the applied electric power, only two teeth (19 and 21) are provided with exciter coils (29 and 31). In order to minimize detent torques the three teeth are identical to each other and the first actuator body is suitably diametrically magnetized.
