The decisive factor is notthe efficiency of individual components, but rather theefficiency of the overall system. There is no benefit in high-efficiency motor design if other components in the systemwork to reduce the overall system efficiency. The EC+concept enables automatic performance optimization forcomponents regardless of source. Therefore, the systemdesigner is free to select an optimal combination ofstandard components for drive, motor, and fan/pump, andstill achieve optimal system efficiency.ExampleA practical HVAC example is the EC version of plug fanswith external-rotor motors. To achieve the compactconstruction, the motor extends into the intake area of theimpeller. This intrusion impacts the efficiency of the fannegatively, and therefore reduces the efficiency of theentire ventilation unit. In this case, high motor efficiencydoes not lead to high system efficiency.AdvantagesThe flexibility of EC+ ensures that such reduction of systemefficiency is avoided, and provides the system designer andthe end user with the following benefits:• Superior system efficiency thanks to acombination of individual components withoptimum efficiency.• Free option of motor technology: Asynchronousor PM.• Manufacturer independency in componentsourcing.• Easy and cost-efficient retrofitting of existingsystems.VLT® DriveMotor FCP 106 with EC+ enable the systemdesigner to optimize system efficiency, without losingflexibility and reliability.• The FCP 106 can be mounted on either anasynchronous or a permanent magnet motor.• The use of standard motors and standard drivesensures long-term availability of components.Programming of FCP 106 is similar to programming of allother Danfoss drives.Application Examples VLT® DriveMotor FCP 10646 Danfoss A/S © 12/2018 All rights reserved.
