    摘要: This work presents a novel design procedure for integrating electric motors
    with gear mechanisms. Based on the configurations of electric motors and the
    kinematic structure of gear trains, the design requirements and constraints are
    concluded. By applying the graph representations and creative mechanism
    design methodology, feasible design concepts are successfully generated
    systematically. The open-circuit magnetostatic field analysis of a DC
    commutator motor conducted by applying 1-D and 2-D equivalent magnetic
    circuit methods are obtained and verified using FEA. The differences in the
    air-gap flux density are 3.21% and 3.06% for 1-D and 2-D methods, respectively.
    The Carter’s coefficient is applied to model the permeance of the slot and
    gear-teeth space. The affection of the integrated gear-teeth on the flux linkage
    and the first derivative of the flux linkage can be ignored. The design methods
    for gear trains, gear profiles, number of gear teeth, and gear strength are also
    introduced. The maximum stress of the gear profile is 312 MPa, and the results
    show that the gear train can be used for transmission purposes. A DC
    commutator motor with a planetary gear mechanism and an AC induction motor
    with an ordinary gear train are applied as examples. A feasible integrated DC
    commutator motor device is presented that reduces the cogging torque and the
    torque ripple by 92.02% and 50.14%, respectively, while increasing the torque
    density by 16.66%. The torque of the AC induction motor is reduced by 8.96%,
    and the torque ripple is reduced by 14.23%. In addition, the torque density is
    increased by 1.75%. This indicates that the integrated devices provide more
    stable and efficiency output torque than the existing design.
