1971 - 1980

In the seventies the factory was at its all-time low. The factory almost went bankrupt, one of the reasons was the decreasing demand for diesel driven generators. But as you can often see, in the regression their started a new evasion. In 1978 Jo Paulides started a new partnership with his son, Sjaak. The company slowly recuperated. A new market was found; the products changed. The company started to design more brushed DC machines for various applications. For example gun-turrets of tanks, parts for ship applications and air-conditioning for cars. Tennant and Gansow ordered a lot of motors for industrial sweepers. This all lead to several extensions to the factory, i.e. storage for small materials (1985), a new production space for metal cutting machines (1987) and at last in 1997 a building used for storing pallets and to paint motors.

Diesel driven welding and mains generator

Another system applications is the diesel driven welding/mains generator, where a 21hp diesel engine (1 cylinder, 4 stroke) of Ruggerini was used to direct-drive a welding and mains generator. The welding generator (12kW; S2-60%) was combined with a mains generator, where the welding generator generated a DC voltage (60VDC with 15 to 200A) and the mains generator supplied the AC voltage (220VAC with 16A). At the 2 pole welding generator a disc was used to short the magnetic flux from the field supply, what resulted in a cheap and gearless control. The mains generator (3.5kVA) supplied the AC voltage and current to two sockets of 16A (fused) at 220VAC. Further, the welding generator was one of the first motors where interpoles were used to minimise the armature reaction field.
