Pump motor for the Red Cross in Syria

Menzel Elektromotoren has manufactured a pump motor for the Red Cross in Syria. This is intended to help stabilize the water supply in communities that have been destroyed in the civil war.

The motor replaces an old vertical motor (type V1) and should not require any structural or design changes in the pumping station. This meant that a wide range of sophisticated features were required. The motor is a very large vertical motor of size 800, with the unusual cooling type IC 511 (tube-cooled), with a smooth round welded steel housing with protection class IP54. Menzel manufactured a special flange for the assembly and equipped the slip ring motor with a short-circuit and brush lift device (KBAV). This lifts the carbon brushes after the motor starts, thus reducing brush wear and the maintenance required for cleaning the slip ring chamber. According to customer specifications, the KBAV was to be located on the drive side. Menzel also implemented this atypical design professionally and within a manageable budget, with various additional work such as the manufacture of additional intermediate rings. The medium-sized company also manufactured the motor shaft and terminal boxes to customer specifications. Before delivery, Menzel subjected the pump motor to thorough testing. This involved the use of a new additional function of the load test bench, a 3 MW angular gearbox that allows load running in a vertical position. An independent test engineer monitored the load test on behalf of the customer. The rated data of the custom-made motor are 1150 kW, 6300 V, 14841 Nm, and a speed of 740 min^-1.
