Multiphase permanent magnet synchronous motor (PMSM) has better performance than traditional motor. Its redundancy makes PMSM keep running after phase-out or phase-out. In this paper, a multi-phase permanent magnet synchronous motor controller based on TMS320F28335 is designed. The design method of minimum system and peripheral circuit of DSP is given. A 50W power supply is

With the rapid development of computer network technology application in Vocational colleges, it is self-evident that network services bring convenience to information-based campus, and efficient security management of data center servers is also essential. This paper mainly analyses the key technology of network migration on domain controller to prevent the serious impact of migration failure,

At present, the single motor wiper system commonly used in automobiles is synchronous swing of wiper arm through mechanical connection. This structure has some shortcomings, such as large space occupation and inconvenient maintenance in case of failure. The dual motor wiper system overcomes these shortcomings and reduces the weight and mechanical noise of the system,

With the wide application of AC motor in the field of electromechanical servo, the hardware design and implementation of an AC servo motor controller based on ARM are introduced. PWM signal generation and control, rotor position detection and speed control are realized by using advanced timer, SPI and QEP interface in the selected ARM processor.
