Description
Titolo: Realizzazione di un motore a basso numero di giri al imentato a corrente alternata trifase Title: Realization of a low rpm motor powered by three-phase alternating current
I l motore sarà costituito da una parte statorica (da 2 a 1 2 pol i e più ) alimentata da corrente alternata trifase di rete (q ualsiasi tensione) e da una parte rotorica con lo stesso numero di poli magnetici dello statore creati da una bobina alimentata da corrente monofase di frequenza leggermente diversa dalla frequenza d i alimentazione della corrente statorica. The motor will consist of a stator part (from 2 to 1 2 poles and more) powered by three-phase AC mains current (any voltage) and a rotor part with the same number of magnetic poles as the stator created by a powered coil. from single-phase current with a frequency slightly different from the stator current power supply frequency.
Per la partenza e la frenatura dello stesso motore si farà in modo che lo statore e il rotore allo stato di quiete abbiano la stessa frequenza di al imentazione e poi la frequenza d i uno dei due elementi (statore o rotore) vari il suo valore di quel tanto che basta per avere il numero di giri voluto. For the starting and braking of the same motor, it will be ensured that the stator and the rotor in the quiescent state have the same power frequency and then the frequency of one of the two elements (stator or rotor) varies its value by that enough to have the desired number of revolutions.
E' chiaro che lo statore o il rotore dovranno essere al imentati da due o tre spazzole di carbone su anelli d i materiale adatto. Si fa notare che il rotore può essere esterno allo statore e potrà quindi essere munito di tre spazzole per la sua alimentazione trifase. It is clear that the stator or rotor will have to be fed by two or three carbon brushes on rings of suitable material. It should be noted that the rotor can be external to the stator and can therefore be equipped with three brushes for its three-phase power supply.
Il vecchio motore asincrono trifase ad anelli, opportunamente calcolato può anche benissimo fu nzionare alla stessa man iera del motore portato in brevetto facendo sempre in man iera che il rotore e lo statore siano alimentati con frequenze diverse . Ciò permette di avere il numero di giri voluto che è funzione della differenza delle due frequenze e del numero dei poli del motore stesso. The old three-phase asynchronous ring motor, suitably calculated, can also work very well in the same way as the motor brought in the patent, always making sure that the rotor and stator are fed with different frequencies. This allows to have the desired number of revolutions which is a function of the difference between the two frequencies and the number of poles of the motor itself.
Questo tipo di motore si può applicare in molti casi (apparecchi d i sollevamento e altro). Per variare la frequenza d i al imentazione si possono usare vari tipi di convertitori a frequenza variabile. (ac-dc-ac o dc-ac). This type of motor can be applied in many cases (lifting equipment and so on). Various types of variable frequency converters can be used to vary the input frequency. (ac-dc-ac or dc-ac).
Lo stud io per cu i è stato fatto è soprattutto applicabile come macchina senza riduttore nel campo degli ascensori dove nella puleggia di trazione si possono contenere tutte le apparecchiature necessarie al movimento e alla frenatura della macch ina. In variante si può realizzare un'alimentazione allo statore (parte interna) in corrente continua e un elevato numero d i pol i sia sullo statore che sul rotore. (Il numero di poli magnetici del rotore sono uguali al numero dei poli dello statore) . La frequenza di alimentazione deilo statore in questo caso sarà più bassa ma avremo una coppia più controllabile e la frequenza alla partenza partirà da zero fino a raggiungere la frequenza del la velocità voluta. The study for which it was made is especially applicable as a machine without gearbox in the field of lifts where all the equipment necessary for the movement and braking of the machine can be contained in the traction pulley. Alternatively, it is possible to provide a direct current supply to the stator (internal part) and a high number of poles both on the stator and on the rotor. (The number of magnetic poles of the rotor are equal to the number of poles of the stator). The stator power supply frequency in this case will be lower but we will have a more controllable torque and the starting frequency will start from zero until reaching the desired speed frequency.
