Abstract
Methods, systems, and apparatuses for motor hotspot identification. One system includes a first motor installed in a vehicle, the first motor including a stator having at least one stator winding corresponding to one phase of the first motor. The system also includes a first set of temperature sensors coupled to the first motor and a controller. The controller receives a motor operating condition signal of the first motor, accesses a stored correlation model, and generates hypothetical temperature measurement data for a hypothetical temperature sensor of the first motor based on the stored correlation model and the motor operating condition signal. The stored correlation model is generated based on motor operating condition signals associated with a second motor operating in a test environment. In response to identifying a hotspot within the first motor based on the hypothetical temperature measurement data, the controller modifies operation of the first motor.
