Abstract
An electrical actuator has a DC motor which is provided with a rotor having a permanent magnet for forming a plurality of magnetic poles around a periphery thereof and a stator having a plurality of energizing coils and being disposed around a periphery of the rotor to thereby generate a rotary force for the rotor. In mounting this DC motor on a heat-generating member which generates radiant heat, a member for shielding radiant heat from a heat-generating member is disposed between the DC motor and the heat generating member. In this manner, the radiant heat from the heat-generating member is prevented from reaching the DC motor, whereby the problems in the DC motor associated with the radiant heat can be prevented.
