Business Profile

     Having edge of the proactive local climate of the 70s, in 1977 the engineer Felice Caldi, who had usually been a passionate builder and inventor, founded an revolutionary organization, running internationally in the subject of computer software for industrial machinery.
Given that then, this tiny company dependent in Lodi has enjoyed constant successes relevant to progressive goods and chopping edge “best in course” systems in the field of industrial automation, as confirmed by the numerous patents submitted during the a long time as nicely as the crucial awards provided to it by the Chamber of CZPT of Milan and of the CZPT rdy Area.
    The organization, thanks to its successes more than time, has developed noticeably, growing its product sales network overseas and opening yet another business in CZPT to control the product sales circulation in the Asian marketplace. 
    CZPT attentive to the dynamics and needs of the automation marketplace, continuously evolving and regularly searching for technological innovation, CZPT CZPT ttronica has been ready to react to all the technological issues that have arisen more than the many years, offering remedies capable to make its CZPT er’s equipment far more and a lot more performing and highly aggressive.
    And it is precisely to underline the value and the uniqueness of each and every one CZPT er that we style, with care and commitment, very CZPT ised automation options, that are in a position to completely meet any request, the two concerning application and components.
    Our team of mechatronic engineers can without a doubt CZPT ise the application with specifically developed firmware, and it can also adapt the motor by CZPT ising, for illustration, the duration of the cables or the diameter of the crankshaft and the IP safety degree, all strictly dependent on the CZPT er’s technical specifications.




Synchronous motors operate at a pace that is synchronous with the frequency of the mains present. This indicates that in the regular-condition of the motor, the rotation of the shaft is synchronized with the frequency of the offer present. The interval of rotation of the shaft is equivalent to the amount of AC cycles. The stator of a synchronous motor has polyphase AC electromagnets. These electromagnets create a magnetic subject that rotates in synchrony with the present in the wire. The rotor outfitted with permanent magnets or electromagnets rotates synchronously with the stator magnetic area to form the second synchronous rotating magnetic discipline of the AC motor.
