fft calculations once per hour and starts per day are counted if the motor 102 is off no data is stored and the monitor 100 is set to capture the acceleration time upon start up other sources of electrical power suitable for use within the monitor 100 are available for example the 3 volt battery of the preferred embodiment could be replaced with a peltier device this type of device includes a material which when heated on one side and cooled on the other produces electrical power the larger the temperature differential the more power that the device is able to produce the peltier device would take advantage of motor heat to elevate the temperature of the hot side of the device while ambient cooling would be used to reduce the temperature of the cold side as another alternate source of power a 120 volt power line can be connected to the monitor 100 during operation of an electric motor 102 heat generated by the motor is typically transferred by the motor frame 104 to the ambient air creating a heat blanket that surrounds the motor frame 104 a heat blanket may also result from external factors such as heating induced by absorption of sunlight under certain conditions with some motors this heat blanket can be large enough to adversely effect the accuracy of the ambient temperature sensor 122 and.
