In this paper,the carousel storage with spindle direct tool changer of vertical machining center TH7130 is introduced with its structure and working principle,the working process of automatic tool changer and the design of the principle of pneumatic control and electric control.

For solving the existing problems of machine braking and electrical braking during the process of stoppage of a turbogenerator set,a magnetic reducing method is recommended,which can greatly reduce the current of generators at switch due to remainder magnetic and abate the demand for braking switch.

The four kinds of electrical braking modes of AC inverter speed regulation systems, DC braking?power braking?regenerative braking and intercommunity DC BUS multi-inverter drive are detailed, the applying ranges and modes selection and calculation of different braking modes are given.

In order to acquire dynamics performance of threephase induction motor during electrical braking operation, the simulation model was established based on MATLAB/SIMULINK, according to mathematical model of induction motor in dq still coordinate system.
