摘要： A method and system of reducing/eliminating ripple in an electric motor. An electric parameter, such as current is sensed in an input electric signal. Ripple is detected in the signal using one or more current sensors and a discrete Fourier transform calculation. Ripple is reduced by adjusting the electric signal being sent from a drive control to an electric motor, using a closed-loop configuration. The electric motor might be a regenerative electric motor that is configured to sink or supply electricity to a power grid.

摘要： A brake assembly for an elevator system includes a guide rail configured to guide movement of an elevator car. Also included is a safety brake operatively coupled to the elevator car and having a brake surface configured to frictionally engage the guide rail. Further included is a safety brake actuation mechanism (30) operatively coupled to the safety brake and configured to actuate the brake member to a braking position. The safety brake actuation mechanism (30) includes a sensing device (40) disposed at a distance from the guide rail to determine a speed of the elevator car relative to the guide rail. The safety brake actuation mechanism (30) also includes a first rigid plate (52) having an inner edge disposed at a distance from the guide rail that is less than the distance that the sensing device (40) is spaced from the guide rail to prevent the sensing device (40) from contacting debris disposed on the guide rail.
