Title: Control of drum winder drive in mine shafts
Inventor: LEWIS E A
IPC: H02P5/68
Filed: 1984-10-31
Abstract: A motor control system for a double drum mine winder in which the drums are not mechanically coupled but are driven by respective motors MLH, MRH and convertors A1, A2. Conventionally, when one motor is raising its load and the other lowering its load, one convertor provides a load on the supply and the other regenerates energy to the supply. The very wide range of convertor operating conditions that this implies causes a poor power factor and consequent inefficiency. According to the invention the motor convertor loops are coupled by a further convertor A3 which carries the greater current of the other two. Each motor in a generating condition then serves to provide at least part of the energy supply to the loaded motor and a significant improvement in power factor is achieved. <IMAGE>

Title: Shaft misalignment monitoring
Inventor: BRITTON JOHN D
IPC: G01B7/31
Filed: 1985-09-12
Abstract: A shaft misalignment monitoring system comprises a coil L1 on one side of a coupling connecting two co-rotating shafts and a ferromagnetic rod A on the other side of the coupling, the rod being so positioned within the confines of the coil that misalignment of the shafts alters the relative disposition of the rod and coil so as to affect the inductance of the coil, the coil forming part of an alternating current circuit an operating parameter of which is variable in dependence upon the inductance of the coil and which variable operating parameter is monitored. The coil may form part of a Colpitts oscillator producing a frequency which varies over one revolution to a degree determined by angular misalignment and with a phase relative the signal from a reference generator 56 indicative of the direction of misalignment; average frequency reflects axial misalignment. The signal is mixed with a reference frequency signal and controls a shunt across the secondary of a rotory power input transformer, to modulate the signal applied to the primary winding. In a second embodiment only the coil and one winding of a rotary transformer rotate with one of the shafts, the transformer secondary feeding an AC bridge circuit. <IMAGE>
