  • Patent number: 9756788
    Abstract: Apparatus and methods for cooling controller assemblies for electric utility vehicles are disclosed. Auxiliary implements powered by electric motors onboard a utility vehicle create airflow that is captured and directed to provide increased ambient airflow across heat sinks used to dissipate heat from heat generating components. Airflow across heated surfaces is further created by vehicle movement and vacuum pressure. Fins and other heat dissipating architecture are employed. Features of the cooling systems enable increased controller assembly functionality and/or decreased controller assembly package size.

  • Publication number: 20130257317
    Abstract: Electronic control systems and related control methods for controlling electric drive motors for propelling a vehicle and electric auxiliary motors for performing work, such as electric deck motors for mower blades. The apparatus is shown in use with a vehicle that includes a mowing deck. Features of the control systems allow for safe and efficient use of the vehicle. Controller assemblies and packaging for electronic control systems of electric motors utilized in utility vehicles or other power equipment are also disclosed. The controller assemblies are packaged for robust design and heat dissipation, while collectively housing the controllers, switches and sensors needed to operate multiple motors performing different functions, or the same function in serial.
