Abstract
As an adjustable speed drive the electronic constant-current motor system has the same characteristics as the variable voltage system but with a minimum complement of power tubes. Its constant torque characteristics simplify its use for certain classes of application, such as maintenance of tension. These installations range in size from 1/4 horsepower to 7 1/2 horsepower and have a definite advantage in use with electronic control.
