As an indispensable part of modern industry,motor plays a very important role in people’s daily life.The development of motor industry not only drives the economic development,but also intensifies people’s requirements for motor performance.the multi degree of freedom movement of traditional motor needs to add many auxiliary transmission devices on the output shaft to complete.Using this actuator structure will not only increase the volume of the actuator,but also make the actuator more difficult to maintain.How to effectively manufacture the actuator that is more in line with the modern economy The actuator is a key point in the development of modern motor.So far,in order to effectively improve the performance of multi degree of freedom actuator and reduce its volume and maintenance difficulty,some design principles of multi degree of freedom motors are proposed.These multi degree of freedom motors can realize multi degree of freedom motion in space.Compared with the traditional multi degree of freedom motors,they can be better applied to some fine occasions and high efficiency applications Field.This paper mainly explores the design principle of multi degree of freedom motor and multi degree of freedom generator,and makes a basic research on their performance.Firstly,the research status of multi degree of freedom motor at home and abroad is introduced,and the main research content of this paper is introduced.Several design principles and methods of multi degree of freedom motor with different principles are proposed.Taking the multi degree of freedom motor and generator as examples,the three-dimensional model of multi degree of freedom motor is established,and its basic performance is simulated and analyzed.This paper introduces the electromagnetic system of a multi degree of freedom motor with spherical structure,studies it with the method of field circuit coupling,puts forward four analytical methods which can be applied to the eccentric state,and verifies its accuracy,and puts forward an effective and feasible optimization method for the cogging torque of multi degree of freedom permanent magnet motor.The structure of a multi degree of freedom motor with non spherical structure is optimized.Compared with before and after optimization,the slot full rate,the stability of motor operation,the electromagnetic density and the torque of motor are effectively improved.This paper studies the electromagnetic system of multi degree of freedom generator,and proposes a structure optimization method based on Taguchi algorithm and a control parameter optimization method based on parametric scanning.The experimental results show that the two methods can effectively improve the operation efficiency of the generator,and obtain the most suitable structural parameters and control parameters.Under this optimal structure and optimal control parameters,the generation law of the generator is obtained through analysis and exploration,and its generation characteristics are described in detail.Finally,build the experimental test platform.The data obtained from the above experiments are analyzed and compared with the results obtained from the finite element simulation,which is consistent with the expectation. |
