Motivation is also known (commonly known as motor), used in circuit letters M (the old standard with the D) said. Its main role is to produce drive torque, as with a variety of electrical or mechanical power source. Generator circuit used in the letter G said. Its main role is to use mechanical energy into electrical energy, the most common is the use of heat, water, etc. to promote the generator rotor to generate electricity, with wind power technology matures, wind power has gradually been brought into our lives. This motor design for a certain amount of research, through the calculation of the parameters of the motor and thus more realistic to understand the practical effect of the motor. BBCs first use of electrical design software greatly reduces the time required for motor design. The motor for the three-phase asynchronous (induction) motor, its wide range of uses, good fitness can be used in a variety of places, is currently the most popular motor variety. Key words: electromagnetic, electric, three-phase asynchronous (induction) motors 目 录 1电机简介--------------------------------------------------------------------------------------------------------5 1-1 电机制造工业的近况与发展趋势-------------------------------------------------------------------5 1-2 国家标准 国际标准---------------------------------------------
