Abstract: A system and method for cooling an enclosed position feedback device mounted to a motor is disclosed. An active cooling device is mounted between the position feedback device and the housing enclosing the position feedback device. A compliant mount is provided to accommodate vibration in the position feedback device. The compliant mount may be a compliant thermal pad positioned between the feedback device and the active cooling device. Optionally, the compliant mount may be provided between the motor and the position feedback device.

Abstract: An improved system for monitoring vibration of an electric machine is disclosed. According to one embodiment, sensors are positioned in a plane orthogonal to the motor shaft and each sensor detects vibration along at least one axis of the motor. The sensors are oriented such that the polarity of each sensor is reversed. The pairs of sensors may be used to isolate specific vibrations within the motor. According to another embodiment, a sensor may be mounted directly to the motor shaft. The sensor on the motor shaft directly detects vibrations along the motor shaft. Optionally, a second sensor may be mounted to a fixed location within the motor housing, and the combination of the sensor on the motor shaft and the sensor at a fixed location may be used to isolate specific vibrations within the motor. A motor controller may adjust operation of the motor to reduce the isolated vibration.
Abstract translation: 公开了一种用于监测电机振动的改进系统。 根据一个实施例，传感器定位在与电动机轴正交的平面中，并且每个传感器沿着电动机的至少一个轴检测振动。 传感器被定向成使得每个传感器的极性相反。 传感器对可用于隔离电动机内的特定振动。 根据另一个实施例，传感器可以直接安装到电动机轴上。 电机轴上的传感器直接检测电机轴的振动。 可选地，第二传感器可以安装到电动机壳体内的固定位置，并且电动机轴上的传感器和固定位置处的传感器的组合可用于隔离电动机内的特定振动。 电机控制器可以调节电机的运行，以减少隔离振动。
