In this video you will see the restoration of a very old electric motor, from what I could find out it is from the year 1930 approximately, below I will leave you a little history about the company that manufactured this emblematic motor.
EMF Dordt is the name by which Willem Smit & Co.'s Electromotorenfabriek Dordrecht became known. This company existed from 1910 to 1977 in Dordrecht, in the Dutch province of South Holland, and the company manufactured electric motors.
History
EMF Dordt originated from the Smit Slikkerveer company and was founded by Willem Benjamin Smit. As the demand for electric motors increased, Smit Slikkerveer began to focus on large, specialty motors and generators. Series production of the most common engines would have to take place in a separate factory and a site for this was found in Dordrecht. Therefore, the company used the name: Smit Dordt as its logo. It was agreed that the engines manufactured in Dordrecht should not exceed 15 hp (11 kW). The largest engines would be manufactured at Slikkerveer.
In 1914 the limit was increased to 18 CV and in 1915 to 30 CV. In 1918, however, the demand for engines over 30 hp was also met and now EMF Dordt became a competitor to Smit Slikkerveer. The company name has now been changed to EMF Dordt. The company grew well. The registered capital (NLG 200,000) already doubled after two years (in 1913) and even increased to NLG 1 million in 1918. At that time it employed 160 people, in 1920 to 180. In addition to the factory (three floors) at Korten Parallelweg, the company also owned a factory building in 's-Gravendeelsedijk (including dyers). The 1920s were reasonably prosperous and the company was not even relatively affected by the economic crisis of the 1930s. In 1933, the Vereenigde IJzerfabrieken electric motor construction department became De Vijf in Doetinchem taken. In mid-1932, the NV Electric Machine Company, abbreviated EMO, was founded as a subsidiary, into which the manufacture of household items such as vacuum cleaners was incorporated. After initial success, it was liquidated again in 1940.
