Abstract: A motor controller having low standby power consumption is provided. The motor controller includes a direct current (DC) bus. The motor controller also includes a low-power supply. The motor controller also includes an inverter configured to control a supply of current to stator windings of a motor. The motor controller also includes a switch circuit coupled between the DC bus and the low-power supply. The motor controller also includes a switch controller coupled to the switch circuit and configured to be coupled to a system controller. The switch controller is configured to control the switch circuit to electrically decouple, in response to detecting an absence of a control signal from the system controller, the DC bus from the low-power supply.

Abstract: A motor controller and methods for operating a motor are described herein. The motor controller includes a high-frequency (HF) inverter having a direct current (DC) input stage and an alternating current (AC) output stage, the HF inverter operable at a switching frequency to generate a three-phase output having a fundamental frequency. The motor controller also includes a differential mode (DM) filter coupled in series with the output stage of the HF inverter and having a resonant frequency less than 10% of the switching frequency, the DM filter configured to reduce harmonic components of the three-phase output and generate a first filtered output. The motor controller further includes a common mode (CM) filter coupled in series with the DM filter, the CM filter configured to filter the first filtered output to generate a second filtered output having a reduced CM voltage to operate the electric motor with a reduced bearing current.

Abstract: A motor controller for controlling an electric motor includes at least one integrated sensor disposed on the electric motor. The least one integrated sensor is configured to collect sensor data associated with a status of the electric motor for a period of time, the period of time beginning at an activation time and extending at least until an installation time. The motor controller may include an energy management system configured to power the at least one integrated sensor for at least a portion of the period of time, and a memory device configured to store the sensor data. The motor controller may include a data management system configured to communicate the sensor data from the at least one integrated sensor to at least one of the memory device and a remote device.

Abstract: A ground assembly includes a first layer, a second layer, and a bypass capacitor. The first layer includes a power ground, a communication ground spaced from the power ground, a conductive path defining a parasitic inductance and electrically coupled between the power ground and the communication ground, and an electrically insulating layer. At least a portion of the insulating layer is positioned between the power and communication grounds. The second layer includes a first substrate that is spaced from the power ground to define a first parasitic capacitance therebetween and is spaced from the communication ground to define a second parasitic capacitance therebetween. The bypass capacitor is electrically coupled between the power ground and the first substrate.
