ABB is the world’s leading manufacturer of low voltage variable speed electric drives.  ABB provides a complete line of energy-efficient electric drives and drive systems to a wide range of industries and applications.  AC drives are used to control the speed and torque of a standard induction motor, the workhorse of industry.  ABB is a market leader in both motors and drives worldwide.  AC drive technology extends the motor speed range from zero to high above the rated speed, increasing the productivity of the driven process. When a low capacity is enough, the drive reduces the machine speed and saves energy.
