Atlantic Controls Unclaimed

Did you know that we can supply you with a mechanical solution to speed control on an electric motor driving a centrifugal load like a pump or fan? The MAGNADRIVE ASD range of adjustable speed drives transmit torque through an airgap from the motor to the driven load. There is no physical contact between the motor and the load, thus your motor always starts up under no load conditions. By varying the airgap inside the drive, the torque transmitted by the rare earth magnets to the copper plate assembly is increased and infinite speed control is achieved within the motor's rated speed. Because the drive is purely mechanical there is no harmonics generated back into the supply, the quality of the supply does not affect the drive, the same drive can be used for low and medium voltage applications and because there is no direct connection between motor and load, the motor is cushioned from any vibration or jam-ups caused by the load. Furthermore if anything goes wrong with the speed control electrics,i.e. the control of the linear actuator, you can still control the speed of the drive manually! Guaranteed spares availability for at least twenty years means that there will not be a "new improved model" like with so many VFD's. We have the perfect answer to speed control right now.
