摘要： A three-phase regenerative drive (20) is operated based upon power from a single-phase AC source ( 12) and power from a DC source (14). The single-phase AC input power and the DC input power are converted to DC voltage on a DC bus (24) by a three-phase converter (22). DC power is provided from the DC bus (24) to a three-phase inverter having outputs connected to a motor (34). A controller (44) controls operation of the three-phase converter (22) based upon contribution factors of the AC and DC sources ( 12, 14) during motoring and regeneration. The controller (44) also controls an AC component of current from the DC source to reduce ripple current on the DC bus (24).

摘要： An exemplary device for determining a position of a component moved by operation of a motor includes a rotating member that rotates responsive to operation of the motor. At least one accelerometer is supported on the rotating member. The accelerometer provides at least one of an indication of a tangential force that is tangential to a direction of rotation of the rotating member and a radial force that is perpendicular to the tangential force. A controller determines the position of the component based upon the force indication from the accelerometer.

摘要： .Power is managed in an elevator system including an elevator hoist motor (12), a primary power supply (20), and an electrical energy storage (EES) system (32). A power demand of the elevator hoist motor is determined, and a state-of -charge (SOC) of the EES system is determined. Power exchanged between the hoist motor, the primary power supply, and the EES system is controlled based on the power demand of the hoist motor and the SOC of the EES system.
