| titleOfInvention | Constant tension control system for a dc reel drive motor |
| abstract | A constant tension system for a direct current reel drive motor operating to wind or unwind a coil of strip material moving at a line speed. A coil diameter signal D is derived which is a function of the instantaneous coil diameter, the coil having a finite diameter Do when the reel drive motor is at the weakest motor field setting. A motor field controller coupled to receive the coil diameter signal regulates the field flux phi so that when D>Do, phi is a function of D, and when D < OR = Do, phi is a constant. An armature current controller is coupled to receive the coil diameter signal D and to control the armature current Ia so that when D>Do, Ia is constant, and when D < OR = Do to enable the operator to reduce line speed so that the reel drive motor will not exceed its highest rated voltage and speed. |
