High-voltage motor:
Make: EMZ | Power: 450-800 kW | Voltage: 6,000 V | Frequency: 50 Hz | Speed: 1,490 rpm | Protection class: IP55 | Cooling type: IC411
Low-voltage motor:
Make: EMK | Type: B3 | Power: 5.5-90 kW | Voltage: 400/460 VD | Frequency: 50/60 Hz | Speed: 1,489/1,787 rpm | Protection class: IP55
In April 2021, EMZ was able to deliver two major orders for a renowned German pump manufacturer on schedule. A total of 35 high-voltage motors and 34 low-voltage motors were manufactured for this project.
The motors in the power range from 5.5kW to 800kW drive various special pumps in flue gas desulfurization plants (FGD) in coal-fired power plants in Turkey. While the low-voltage motors were manufactured in accordance with the applicable energy efficiency specifications, the high voltage motors had to comply with the special regulations of the power plant operators. Among other things, the high voltage motors were manufactured with silencers for the cooling air inlet, which limit the sound pressure level to 85db(A). Furthermore, the speed and the direction of rotation of the motors are monitored with additionally installed incremental encoders so that any reverse rotation of the pumps by the returning pumped medium is reliably detected and prevented. The prevailing very warm and humid climate requires optimized corrosion protection. With a special coating and 220µm layer thickness, the motors are also prepared for this requirement in the coming years.
