The advantages of permanent magnet technology together with the simplicity and service-friendliness of an induction platform. Each motor-drive package combines proven stator technology, an innovative magnet-free rotor design, a best-in-class industrial drive and advanced software to offer a complete, optimized solution.
The permanent magnet motor range extends the effective nominal speed range of the rugged industry workhorses down to 100 – 850 r/min. The motors can simplify drive systems by effectively eliminating the need of speed reduction devices. They are designed exclusively for frequency converter supply, where they provide high speed accuracy even without speed sensors because they are synchronous motors without rotor slip.
The roller table motors supplied by ABB are squirrel cage motors which are specially designed for use with frequency converters. Robust in construction, the motors are fully sealed to withstand the tough conditions in rolling mills.
The motors are low speed units intended for direct connection to rollers. The pole number and frequency can be selected, avoiding the need for gearboxes and therefore saving on maintenance costs and increasing the overall efficiency of the drive.
HDP series have been designed to be used in rough operating conditions and to operate only with a frequency converter. Square frame design and high overload capacity gives the motor an excellent dynamic response due to low moment of inertia and high pulse torque.
