- Electric Drives And Electromechanical Systems: Applications
Electric drive is an electromechanical system, which performs the conversion of electrical energy to mechanical energy or vice versa for running various processes such as: production plants, transportation of people or goods, home appliances, pumps, air compressors, computer disc drives, robots, music or image players, etc. To couple electrical motor with mechanical load, the mechanical drives are used. The basic types of mechanical drives are: geared transmission – provides specific fixed type ratios; belt drives - provide flexibility in the positioning of the motor; chain drives – provide infinitely variable speeds; traction drives – provides adjustable speed with relatively high speed. Rotating parts of the motor and mechanical load are the main components of the mechanical part of drive. Usually they have different parameters of the movement, therefore intermediate mechanical chains such as shafts, reducers, belt-drives and screw-drives as well as clutches are used. Always there is a proper parameter of interest, for example, inertia, speed of rotation, elasticity of mechanical chains, characterizing the movement of these parts or entire system. Mechanical part consists of all system chains linked between them mechanically and revolving with different speeds. To simplify solution of the problem usually the simplest case is considered, when electric motor and the load are connected with absolutely stiff shaft and both parts rotate with the same speed. The book discusses the movement of mechanical part, which consists of actuator (motor) and elastic mechanical load and dependences of controlled parameters upon elasticity and possible clearance in detail, when torque, developed by the motor is not constant but varies in time by exponential law. For an electronics engineer, the book has value in its coverage of the various mechanical components used in motion systems.
