Fan Motor for Cement Plant With Express Custom Configuration

IN MANY CASES, PLANT OPERATORS urgently need an industrial motor which would normally take six months to produce. On top of that, the motor will often need to be customised. Menzel recently experienced this with a fan motor for a privately run Algerian cement plant. Within 13 weeks, the Berlin-based familyrun company was able to build a robust replacement for a failed slip ring motor, which was then flown out to the customer.

A number of individual adjustments were required so that the new motor could smoothly replace the existing model. Menzel was able to reduce manufacturing time to a minimum by using components in stock and adjusting them accordingly. The highly robust MEBSSL-type 6-pole slip ring motor in frame size 630 has a rated output of 1,950kW, an operating voltage of 11,000V and a rated torque of 18,754Nm. It is suitable for operation in both directions of rotation and features protection class IP55 with IC 611 cooling (air-toair heat exchanger). Menzel replicated the dimensions of the original motor that were crucial for interchangeability – shaft dimensions, foot mounting holes and terminal box positions – and also manufactured special terminal boxes to the customer’s specifications. Despite the urgency, Menzel even implemented other special requests, such as the installation of a filter monitoring system and a particular brand of vibration sensors, which must fit into the existing monitoring architecture. The motor manufacturer won over the customer with expert and continuous advice, including on-site support during commissioning.
