Special adaptation on a gigantic scale: 22 ton motor for Malaysia

Menzel Elektromotoren have constructed a 100% compatible replacement induction motor for a Malaysian power plant and are also ensuring its delivery, installation and eventual commissioning on site. The plant operators had turned to Menzel, because the special motor manufacturer had already carried out an earlier urgent order to their satisfaction. Featuring 1,300 kW rated power, 11,000 V voltage and a speed of 372 min-¹, the motor is designed for 36 tons mechanical tensile stress on the shaft.

The power plant needed the motor as a long-term replacement for an aged Mitsubishi motor, that drives a pump. Even for Menzel, who manufacture and deliver large motors up to 20,000 kW, this drive was an unusually powerful specimen. The 16-pole motor in frame size 900 weighs in at 22,600 kg and requires a ladder and platform for the operating staff due to its height of 4.70 m. To be painted and delivered, it had to be dismantled into individual component parts. The customer attended the test run in Menzel's in-house load test field in Berlin. Commissioning will take place on site in Malaysia by Menzel's engineers.
