摘要： A motor controller assembly is configured for use with an electric motor and includes a controller and an absorbent pad. The controller includes a capacitor with a capacitor shell and a liquid electrolyte contained therein. The capacitor shell has a frangible rupture area that opens during a capacitor rupture event to permit the discharge of liquid electrolyte from the capacitor shell. The absorbent pad overlies the rupture area to collect discharged liquid electrolyte.

摘要： A tool for programming a controller of an electric motor by engaging a connection block of the motor and providing high voltage power and communicating programming signals to the controller. The tool includes a body having an interface for engaging the connection block, and internal wiring presenting tool terminals at the interface for making contact with corresponding motor terminals to allow for providing power and communicating signals between the tool and the controller. An energy-limited transformer having an isolated high impedance secondary winding provides both electrical isolation to protect against shock and low energy output to protect against arc flash. Redundant interlocks include a software interlock which allows the power to be present at the interface only during actual programming of the controller. A light ring encircling the body indicates the presence of high voltage and is visible from multiple directions.

摘要： A motor comprising a rotor, a stator, a motor shell, a pair of motor endshields, and a controller housing is provided. The rotor is rotatable about an axis. The stator presents opposite axial ends. The motor shell extends around the axis to at least partly circumscribe the rotor and stator. Each motor endshield is positioned adjacent a respective one of the stator ends and provides support for the rotor. The fastener extends through and interconnects the stator and endshields. The controller housing defines an electronics compartment positioned radially outside the motor shell. The controller housing includes a connector that receives the fastener so as to fix the controller housing to the stator and endshields.
