✦ Synopsis

Among hybrid type (HB type) stepping motors, the 2-phase type is widely used, as is the 5-phase type for high-resolution purposes. On the other hand, the 3-phase type is considered to be superior to other types from the viewpoint of cost performance. However, no study has been made of 3-phase HB type stepping motors. In this paper, the performance characteristics of an HB type 3-phase stepping motor are analyzed, and, further, the influence of motor structure and of excitation modes on the motor performance are also investigated. As a result, the relationship between number of stator main poles and number of rotor teeth is formulated. Torque versus angle characteristics, step response characteristics, and pullout torque characteristics are clarified under the various excitation modes in Y-and D-winding connections.
