IPC: A63B55/60
Filed: 1995-10-27
Abstract: PROBLEM TO BE SOLVED: To realize regenerative braking to automatically detect excessive speed to limit the speed by providing a theoretical controller which receives a signal from a current detecting means of an armature winding and a field winding of a shunt DC power generator, and starts electrical braking when the direction of current flowing through the armature winding is inverted. SOLUTION: Amplitude and polarity of an armature current is monitored with an amplifier 96 connected to the terminals of a current sensor 46. During the normal operation, the motor terminal A1 is positive for the terminal A2 and a current flows to the bus 40 from the bus 38 via the armature current sensor 46, an armature 42 and a switching element 44. However, under the excessive speed condition, the armature rotates in the speed higher than the commanded speed, it operates as a power generator. An armature current inverses the direction and a regenerative current flows inversely through the diode 50, armature 42 and current sensor 46. As a result, a field current increases, speed is lowered with a large torque and the regenerative braking is operated.

Filed: 1989-10-27
Abstract: PURPOSE:To prevent a false operation due to a bound without fail by setting a pulse monitoring time in consideration of the speed of rotation of an object of measurement and the switching characteristic of a sensor. CONSTITUTION:A sensor detection signal is wave-shaped by a filter circuit 1 and a Schmitt circuit 2. The edge of the waveform of this signal being used as a trigger, a pulse of a reference frequency from an oscillation circuit 3 is counted in a count circuit 4 and a pulse monitoring circuit 5. When no wave- shaped pulse is generated within a prescribed time, a signal to the effect that an output of the circuit 4 is delivered, as it is, to a subsequent stage is outputted from the circuit 5 to an addition circuit 6. When the wave-shaped output pulse is generated within the prescribed time, that is, when a bound occurs in the sensor detection signal, the circuit 6 is made to hold once the output of the circuit 4 by an output signal of the circuit 5, and thereby a false operation due to the bound of the sensor detection signal is prevented without fail.
