Swift motor replacement

On the Friday night, they turned to Menzel with a request for the construction and delivery of a replacement motor – and by Monday, a new identical motor with customised modifications had already left Menzel Berlin's workshop. Prolonged and costly production downtime was averted. 

Such a quick response was possible mainly due to Menzel's stock of more than 20,000 motors in a power range to 15,000kW. A suitable slip ring motor with 2300kW, 11,000V nominal voltage and a speed of 992 min-¹ that matched the original motor's features – namely constantly running brushes, roller bearings for grease lubrication, and two free shaft ends – was readily available. The availability of in-house load test fields at Menzel also contributed substantially to the fast delivery time.
