<p>A rotary actuator (100) comprises a housing (102) made of a synthetic resin. A rotor (108) carrying a plurality of permanent magnet (152) of alternate polarity with respect to the adjacent magnet, and stator (110) having a plurality of electromagnets (162a-162f) which are selectively energized, are aligned in axial alignment to each other. Magnetic conductor plates are provided in alignment with the rotor and the stator. The magnetic conductor (130, 132) plates ar supported on the inner periphery of the resin housing in opposition to the rotor and the stator for forming part of a magnetic circuit.</p> |
