ZT microcontroller streaking application small three phase motor framework

Beginners microcontroller, will struggle Water pump with the application of its various modules motor vehicle spare part function, such as serial port (232485) for a variety stator of functions of IC AC motor control, motor control, PWM interrupt, timer, human-computer interface stator application, CAN bus, etc. It is a necessary stages in the learning process, is the basic motor rotor skills. After this stage, contact different MCU will be found later, all the same, each have each advantage, and is easy to learn any new MCU of including some complex processors. And control of the MCU programming will enhance a high www.facebook.com/dongfeng.motor profile - is to control all kinds ac generator of peripheral (if the operation of the complex algorithm with DSP), motor vehicle spare part motor electric ac synchronous generator and peripheral and MCU communication mode generally has several sequential:, IIC, SPI, intel8080, M6800. So around the MCU programming is a very simple thing. However, this is only the surface of embedded development, in contact with a variety of MCU, exposed to complex design requirements, run after the operating system and so on, we are back to the single-chip microcomputer bare-metal development, before you know it will consider the whole program design the architecture of the problem; A good application architecture, is an experienced engineers and a beginner's watershed.

The use of 60 hz import motor and power supply design

 In the early 90 s, a rubber manufacturing company the five sets imported from North America (second-hand) rubber equipment, there are two production Farrell 11 d mixer and a SL sullair company - 32 type screw air compressor. Basic situation of the three electrical motor 12v 1000w devices test is good, according to the production requirements, companies need to benefit installation fan motor commissioning as soon as possible; But the use of these equipment there is a big technical problem: the driving gear of these devices is 60 hz five sets of high voltage motor, not directly into the 50 hz power grid of our country. But if all replacement for domestic 50 hz, 6 kv motors and high voltage, need to increase cost nearly 1 million yuan. In order to solve the technical problem, technical personnel for imported equipment of acmotortrading.blogspot.com the power supply system, switch gear, motor parameter and so on has carried on the earnest analysis and calculation, decided to adopt frequency conversion principle, tinkering with the system power supply design.

Stepper motor and ac servo motor performance comparison of different control precision

Two-phase hybrid stepper motor step Angle is 3.6 ° and 1.8 °, 5 phase hybrid stepping motors interval Angle is 0.72 ° and 0.36 ° in general. electric motor single phase motor There are also some high-performance stepper motor step Angle is smaller. Such as cross company produces a kind of stepping motor for wire walking machine, where the step Angle is 0.09 °. BERGER LAHR company in Germany (BERGER LAHR) production of three-phase hybrid water pump price stepping motor where the step Angle can dial the code permanent magnet generator switch is set to 1.8 ° and 0.9 ° and 0.72 ° and 0.36 ° and spare parts 0.18 ° and 0.09 acmotor2.blogspot.com ° and 0.072 ° and 0.036 °, combine www.dongfeng-motor.com the two and five phase hybrid stepper motor step Angle. Control precision of the ac single phase motor servo motor by the motor shaft after the rotary encoder. Panasonic digital ac servo motor, for example, in line with standard 2500 encoder of the motor, drive due to the permanent magnet generator internal used four frequency multiplication technology, the pulse equivalent to 360 ° / 10000 = 0.036 °. For with 17 encoder of the motor, drive each receive 217 electric generator = 131072 pulse motor turns a circle, namely the pulse equivalent to diesel generator set 360 ° / 131072 = 9.89 seconds. Interval Angle is 1.8 ° is 1/655 of the pulse equivalent of stepper motor.
