Title: Slow starting device for motor
Inventor: UDAGAWA RIYUUSUKE
IPC: B66C13/22
Filed: 1979-03-09
Abstract: PURPOSE:To obtain smooth, slow starting of a moter by setting a voltage pattern to be impressed by a combination of timers and function generators. CONSTITUTION:When a switch 1 of a main circuit is closed, the voltage of a function generator FG1 is simultaneously impressed to a motor 3 as the reference voltage of a phase control circuit GC, which controls the phases of controlled rectifier elements 4, 5 of the main circuit. By this, a low torque is produced at the motor and a play in a load system is eliminated. By the operation of a timer T1, the voltage of a function generator FG2 is impressed to the circuit GC, and the motor 3 is caused to start slowly. Next, by the operation of a timer T2, the voltage of function generator FG3 is impressed to the circuit GC and the motor 3 is accelerated. When the rotational speed of the motor approaches the rated rotational speed, a timer T3 operates, the voltage of a function generator FG4 is impressed to the circuit GC, and the total voltage is impressed to the motor 3.

Filed: 1983-02-21
Abstract: PURPOSE:To avoid malfunction due to noise at AFT operation by placing priority over a signal applied earlier timewise when an AFT up signal and an AFT down signal are applied at the same time. CONSTITUTION:First it is discriminated whether the AFT signal is an up signal. When the signal is not the up signal, it is discriminatd whether or not the signal is a down signal.

It is discriminated whether or not the up signal exists in this state. When no up signal exists, the same state is continued and whether or not the down signal exists is discriminated when the up signal exists. When the down signal exists, the state that the frequency of the SIF is lowered sequentially is continued and when the down signal does not exist, the fL is increased sequentially and the frequency of the SIF is increased sequentially. Whether or not the up signal exists is discriminated in this case and the same state is continued when the down signal existis. When the no up signal exists, the AFT operation is stopped.
