  • Methods and systems for transient voltage protection
    Patent number: 9735725
    Abstract: Protection of an electric motor drive controller from a transient voltage is described herein. The transient voltage is provided by an alternating current (AC) power line that includes a line conductor, a neutral conductor, and a ground conductor. The transient voltage protection system includes a first stage protection device coupled to an input of a rectifier of the motor drive controller. The first stage protection device is configured to suppress the transient voltage to prevent damage to the motor drive controller. The transient voltage protection system also includes a second stage protection device coupled between the rectifier and an inverter of the motor drive controller. The second stage protection device is configured to further suppress the transient voltage to prevent damage to the inverter.

  • Electric machine housing
    Patent number: 9431881
    Abstract: A housing for enclosing electronics of a motor having an axis of rotation is provided. The housing includes an end cap having an outer surface and an inner surface. A control board is coupled to the inner surface, wherein the printed circuit board includes a first side, a second side and an edge located between the first side and the second side. The housing further includes a first circuit coupled to the first side which includes a plurality of first electrical components. Each first electrical component includes a tab extending beyond the edge. A second circuit is coupled to the second side and a fastener assembly is coupled to the tab and the inner surface.
