Abstract:

According to the requirements of large torque and high precision linear displacement of the drilling robot, an outer mover (OM) linear-rotary (LR) vernier machine (VM) is proposed with a special support mechanism, which combines an outer rotor VM and a cylindrical OM linear VM. In order to reduce the detent force and improve the displacement accuracy of the linear motion when the proposed motor works at low speed and short stroke conditions, the modular stators and permanent magnet poles are adopted instead of the traditional toroid structure. Since the torque is the main output quantity and the linear motion mainly determines the linear displacement, the design of the rotary unit is taken as the optimization objective firstly. Then, the cogging torque and detent force of OMLRVM are added to the optimization objectives. The electromagnetic and mechanical designs of the proposed motor are calculated based on 3-D finite element model. Compared with the results of the initial topologies I and II, the end effects of rotary and linear units are reduced thanks to the support mechanism, and the amplitudes of cogging torque and detent force are decreased. The idea of combined electromagnetic and mechanical design is an effective way to solve the practical application problems in industrial field.
