He was invited to Pest, Hungary, by Count István Széchenyi and became the casting master at the Roller Mill Plant (referred to as Hengermalom in Hungarian).

At that time, European foundries made wrought iron rims for spoked wagon wheels by pouring the casts in shapes in sand, and leaving them to cool down.

[citation needed] At this time the agricultural machines, steam locomotives, pumps and the railway carriages were the main products.

Prominent engineers at Ganz works included András Mechwart, Károly Zipernowsky, Miksa Déri, Ottó Titusz Bláthy, Kálmán Kandó, György Jendrassik and Ernő Wilczek.

[3] In 1878, the company's general manager András Mechwart founded the Department of Electrical Engineering headed by Károly Zipernowsky.

Engineers Miksa Déri and Ottó Bláthy also worked at the department producing direct-current machines and arc lamps.

The parallel connection and efficient closed core made construction of electrical distribution systems technically and economically feasible.

The Ganz Works built the first transformers using iron plating of enamelled mild iron wire, and started to use laminated cores to eliminate eddy currents[10] In 1886, the ZBD engineers designed, and the company supplied, electrical equipment for the world's first power station to use AC generators to power a parallel connected common electrical network.

[13] In 1894, Hungarian inventor and industrialist István Röck started to manufacture a large industrial ammonia refrigerator (together with the Esslingen Machine Works) which was powered by Ganz electric compressors.

At the 1896 Millennium Exhibition, Röck and the Esslingen Machine Works presented a 6-tonne capacity artificial ice producing plant.

In 1906, the first large Hungarian cold store (with a capacity of 3,000 tonnes, the largest in Europe) opened in Tóth Kálmán Street, Budapest, the machine was manufactured by the Ganz Works.

Until nationalisation after the Second World War, large-scale industrial refrigerator production in Hungary was in the hands of Röck and Ganz Works.

[15] The beginning of gas engine manufacturing in Hungary is linked to Donát Bánki and János Csonka but it is not clear that they ever worked for Ganz.

Ganz produced engines whose designs were licensed to Western European partners, notably in the United Kingdom and Italy.

Between 1901 and 1908, Ganz Works of Budapest and de Dion-Bouton of Paris collaborated to build a number of railcars for the Hungarian State Railways together with units with de Dion-Bouton boilers, Ganz steam motors and equipments, and Raba carriages built by the Raba Hungarian Wagon and Machine Factory in Győr.

The Ganz company started to export steam motor railcars to the United Kingdom, Italy, Canada, Japan, Russia and Bulgaria.

In 1894, Hungarian engineer Kálmán Kandó developed high-voltage three-phase AC motors and generators for electric locomotives.

The first-ever electric rail vehicle manufactured by Ganz Works was a 6 HP pit locomotive with direct current traction system.

Under the management, and on the basis of plans from Kálmán Kandó, three phase electric power at 3 kV and 15 Hz was fed through two upper wires and the rails.

Italian railways were the first in the world to introduce electric traction for the entire length of a main line rather than just a short stretch.

Kandó was invited in 1905 to undertake the management of Società Italiana Westinghouse and led the development of several Italian electric locomotives.

[21] In 1918,[23] Kandó invented and developed the rotary phase converter, enabling electric locomotives to use three-phase motors whilst supplied via a single overhead wire, carrying the simple industrial frequency (50 Hz) single phase AC of the high-voltage national networks.

[20] After World War I, at the Ganz Works, Kálmán Kandó constructed a single-phase electric railway system using 16 kV at 50 Hz.

Because of the early death of Kálmán Kandó, László Verebélÿ continued the work for the Hungarian State Railways (MÁV).

[citation needed] In 1982/83 Ganz-Mávag supplied an order for electric multiple units to New Zealand Railways Corporation for Wellington suburban services.

In 1974, the locomotive and wagon Works were merged under the name of Railway Vehicle Factory and then the machine construction branch went through significant development.

[33] Now the plant is operated by a new investor as a tenant, Ganz Transformer Motor and Manufacturing Ltd., after the previous owner was unable to finance the production.

Through the 90's Ganz has developed more advanced motors with decreased total weight, increased efficiency and low noise levels in order to satisfy the actual needs of the market and all conditions of the industrial application and to conform to IEC, NEMA, ATEX and EAC standards.
