Menzel Elektromotoren, Germany, manufactures IP67 low and medium voltage squirrel-cage motors up to size 355. TÜV Süd has recently attested the dust- and waterproof construction according to protection class IP67 of an entire low voltage motor type series. The series extends to outputs of 400 kW and voltages of 1000 V. In addition, TÜV Süd has attested Menzel’s procedures for IP67 testing, which the manufacturer also offers for medium voltage motors from its own brand up to 11 kV.
Menzel builds IP67 motors with minimal tolerances, waterproof encapsulated cast-iron casings and terminal boxes. The manufacturer holds stock in its main warehouse of all basic components for dust- and waterproof squirrel-cage motors and can therefore realize very short delivery times for standard designs of IP67 motors. The motors are used worldwide, mainly in pump stations, flood-prone areas, food and drink industries and maritime applications. They can be fully immersed at standstill for a period of 24 hours without any ingress of water. Subsequently, when water has receded, the motors are ready to be switched on again directly. The manufacturer runs comprehensive acceptance tests on its motors in its inhouse load test field before shipping. As part of the test spectrum, Menzel also offers underwater tests for all induction motors with cage or slip ring rotors.
