FIG. 3 shows the structure of a DC servo motor in one embodiment of the present invention. In FIG. 3, reference numeral 8 denotes a DC motor frame, which is fitted with motor brackets 9 and 10 through a spigot joint, and rotatably holds the shaft 13 between the motor brackets 9 and 10 via bearings 11 and 12. ing. The shaft 13 has a laminated iron plate and a motor winding 14. A rotor 16 consisting of a speed generator winding 16 and a speed generator winding 16 is fixed, and a motor winding 14 . Although the speed generator windings 16 and 16 are housed independently in the same rotor groove, their winding diameters and windings are obviously different. Further, a motor commutator 17 and a speed generator commutator 18 fixed on the shaft 13 are connected to the motor winding 14 and the speed generator winding 16 at each segment, respectively, and further to the motor bracket) 9.10.

The motor winding 14 of the rotor 16 is energized by a DC power source applied from an external circuit through the rotor 16, and the rotor 16 rotates around the shaft 13 due to the electromagnetic force of the magnetic flux generated by the permanent magnet field 23. The DC motor of the present invention is used for a servo, and it is necessary to constantly feed back the rotational speed of the motor to a control circuit. The speed generator winding 15 inserted into the rotor 16 rotates when the motor winding 14 is energized from the outside, and due to the interaction with the magnetic flux of the permanent magnet field 23, the speed generator winding 15 has a speed proportional to the rotation speed. A voltage is generated and transmitted through the speed generator commutator 18 and the brush 22 to an external circuit as a speed signal.
