New Factory in SarstedtIn addition to the existing plant, a new state-of-the-art manufacturing facility is under construction at the HELMKE site in Sarstedt (near Hannover, Germany).
Drive systems - engineered by HELMKEHELMKE is a worldwide acknowledged competence for the delivery of complete drive systems. The converter cabinets engineered by HELMKE are projected and manufactured for customized and branch-specific applications.
Delivery of an electrically and mechanically exchangeable reserve motor for two vacuum pump drives, make: Strömberg, type: HSSTL. In its works in Rouen, the company UPM operates two 18-year old Strömberg synchronous motors. The motors are designed with two shaft ends, each motor driving four vacuum pumps. The power of the motors is 1,200 kW, the speeds are 214 1/min (28-pole) and 250 1/min (24-pole). As the vacuum generation is a key function in the paper manufacturing process, UPM had tendered the delivery of a reserve machine.
HELMKE was in competition with all wellknown European manufacturers, also with ABB who could revert to the original manufacturing documents. In the course of this project HELMKE developed an 28-pole synchronous motor in type of construction IM7312. This motor could be installed on the baseframe on site which was cast in concrete.
The technical requirements were as follows:
