Abstract: A motor assembly includes a shaft, a bearing, at least one fluid channel, a temperature sensor, a lubricant supply pump, and a controller. The bearing defines a bearing interface against which the shaft rotates. The at least one fluid channel is fluidly coupled with the bearing interface. The temperature sensor detects a temperature of the bearing. The lubricant supply pump is fluidly coupled with the at least one fluid channel to transport lubricant from a lubricant supply to the bearing interface via the at least one fluid channel. The controller receives the bearing temperature from the temperature sensor, determines a difference between the bearing temperature and a supply temperature of the lubricant, determines a lubricant flow rate based on the difference, and transmits a control signal to the lubricant supply pump to cause the lubricant supply pump to transport the lubricant to the bearing interface at the lubricant flow rate.
