    摘要: Each torque-producing phase current of a multi-phase motor is passed through a filter which includes an R/C shunt to ground and a series, current-compensated choke. Each choke has a winding in series with each phase so that the net current generated by phase currents in the windings is zero, and therefore the net flux generated by phase currents in the highly permeable core of the choke is zero at all times. However, there is significant inductive reactance created by the non-counterbalanced motor leakage currents, which prevent leakage currents from circulating through the motor. Thus, torque-producing motor currents can accurately be measured for feedback, without pollution from leakage currents. LEM current transducers allow use of small, proportional currents in the measuring and suppress inter-phase coupling.

    摘要: A power supply for an elevator drive includes a voltage input, a comparator for comparing the input voltage with a predetermined threshold, a transformer having a primary winding and a secondary winding connected to the elevator drive. The transformer has a single tapped primary winding. When the input voltage exceeds the predetermined threshold input, the comparator output causes power to be supplied to the primary winding via one of an end of the winding or the tapping of the winding, and when the input voltage is below the predetermined threshold, input power is supplied to the primary winding via the other of the end of the primary winding and the tapping of the winding.
