Three phase induction motor wiring diagram - The optocouplers used can be both til111 or cny17-2. Do not attempt to keep at the transformers: these are very small and cheap kinds (2va is enough) and the floating way they may be linked here (no grounded terrible poles!) Is essential to this design. Be carefull when gambling round with this sort of circuitry, due to the fact that there are high voltages everywhere. The virtual enter and the microcontroller are absolutely and optically isolated from the electricity circuitry. If you are in need of a controller for a three-phase motor, you have to continually remember using one of the many modules the enterprise offers in recent times. Factories which includes lust gmbh, siemens (micromaster 410), toshiba, hitachi... All have controll modules of their catalogues. Controlling the velocity of the motor using such a standard solution can be performed by way of sending an analog voltage (0-10v maximum of the time) to the precise input, or, on some models, by sending rs232 commands to their port. The gain of these modules is, among different things, that they serve as a motor protector on the equal time. Also, it might on the cease be cheaper than building the circuits shown above your self. If you want the motor to be y-related, the hassle will be which you need a miles better voltage to paintings from. Using a three-phase rectifier bridge, you can of course use rectified three-phase mains modern-day, however that presupposes its availability. Ass an alternative an insulation transformer 230v/ 400v may be used. However, at the end this may tend to be greater steeply-priced than the circuit given above. The circuit beneath however becomes plenty easier, on account that we do now not require 6 mosfets and no floating powers components:. The speed of a normal 3-section induction motor is a characteristic of the frequency of the deliver voltage. Converting the speed of this type of motor for this reason calls for constructing a 3-segment power frequency convertor. The motive force may be realised using power mosfets (or igtb's) capable of handling excessive voltages and speedy switching speeds. The generated frequency can be programmed in a small % controller or even in a quick fundamental stamp. Notice that at lower than normal frequencies, the voltage should be decreased proportionally. In case you forget this, the motor may also overheat and finally even burn out. (See note at the bottom of this paragraph). The circuits proven right here serve mere instructional functions (despite the fact that they do paintings!) And aren't constantly the most appropriate nor safest sollution.
