Electro-mechanical integrated electromagnetism worm drive is a new transmission. The new type system was established by the use of electromagnetic field theory and space dynamics system. Structure and operating principle of Electro-mechanical integrated electromagnetism worm drive are listed in this paper, and the system transmission ratio, meshing process inter-transmission, corresponding relation...
In this paper, a novel electrostatic harmonic micromotor excited by the electrostatic force is proposed, whose basic operating principle is also described. With the theory of the elasticity and electrostatics, the deformation energy, kinetic energy and the electric field energy are analyzed. Due to the Hamilton principle, the differential equation for the flexible ring out-plane vibration is established...
Toroidal motor is a new-style electric machine. In this paper, the basic principle of the motor is introduced. The forming and controlling of the rotational magnetic field are explained. The worm coil distributions for the motor are investigated. Based on the coordinate transforming principle, equations of the stator and the center curve for the worm groove are deduced and the 3D worm and stator models...
In this paper, a kind of electromechanical integrated toroidal actuator is presented. In the actuator, the toroidal drive, power and control are integrated. The basic structure and operating principle of the actuator are introduced. The parameter relationship for the actuator is presented as well. The forces between the planet and the worm or between the planet and the stator for the actuator are...
