Title: Motor control system
Inventor: HAYASHI KAZUTOSHI
IPC: H02P29/00
Filed: 1985-12-13
Abstract: PURPOSE:To make it possible to change over the smooth speed and tensile force control by feeding forward the load torque estimate value calculated from the motor rotating speed and current value to the output value of the speed control unit. CONSTITUTION:A speed regulator 5 outputs the current command value i* in accordance with the deviation of the speed actual value n from the speed command value. The current command value i* is limited to below the tensile force setting value i r by a limiter 6. A current regulator 7 controls a power converter 1 in accordance with the deviation of the current actual value i from the output of the limiter 6. An estimation computing element 9 estimates the load torque from the speed actual value n and current actual value i, so that the current estimate value is obtained equivalent to the load torque, which is then added to the current command value i*. Thus the establishment of tensile force in changing over from the speed control to the tensile force control can be heightened and the speed vibration suppressed.

Filed: 1990-10-18
Abstract: PURPOSE:To prevent a paper from slacking by providing a 1st pressing roller whose hardness is equal to a forward feed roller and pressed thereto, an auxiliary feed roller higher than the forward feed roller and arranged in a delivery direction, a 2nd pressing roller lower than the forward feed roller and pressed to the auxiliary feed roller, and making a peripheral speed of the auxiliary feed roller in the forward direction faster than the forward feed roller. CONSTITUTION:As the hardness of a 2nd pressing roller 29 is the lowest, it is easy to set a pressing force with respect to an auxiliary feed roller 24 to a small value having a little irregularities. As the hardness of the auxiliary feed roller 24 is the highest, it easily slips with respect to a paper 33 even if it is rotated with a peripheral speed faster than a peripheral speed of a platen 3 at rotating in the forward direction, so that there is no possibility to give an excessive stretching force on the paper 33. Also, when the paper 33 is to be returned to a reverse direction, the auxiliary feed roller 24 follows up with rotation due to the stretching force of the paper 33, so that there is no possibility to give the excessive stretching force on the paper 33. Accordingly, slacks of the paper 33 can be always prevented and the paper 33 can be conveyed with an accurate feed quantity.
