1. An apparatus for conformance testing of a rebuilt motor comprising:
integrator;
a plurality of sensors coupled to the integrator, the plurality of sensors comprising:
a first vibrational sensor configured to sense three axes of vibration of a drive end of a motor under test;
a second vibrational sensor configured to sense three axes of vibration of a non-drive end of the motor under test;
a first temperature sensor configured to sense a first temperature of a bearing housing of the motor under test;
a tachometer configured to sense rotational speed of a shaft of the motor under test; and
at least one processor operatively coupled to the integrator, wherein the at least one processor is configured to execute computer readable instructions to perform a plurality of operations comprising:
receiving a set of test parameters of a conformance test, the set of test parameters comprising:
a vibrational sensor parameter, wherein the vibration sensor parameter is configured to enable sensing from at least one of the first vibrational sensor and the second vibrational sensor;
a temperature sensor parameter, wherein the temperature sensor parameter is configured to enable sensing from the first temperature sensor; and
a rotational speed parameter, wherein the rotational speed parameter is configured to enable sensing from the rotational speed sensor;
receiving a plurality of sensor data simultaneously from the plurality of sensors;
determining that sensor data corresponding to a rotational speed of the shaft exceeds a threshold rotational speed, wherein the rotational speed parameter is configured to define the threshold rotational speed;
store a plurality of time sampled sensor data, the time sampled sensor data comprising:
time sampled sensor data of the first vibrational sensor;
time sampled sensor data of the first temperature sensor; and
time sampled sensor data of the first rotational speed sensor;
wherein the plurality of time sampled sensor data is defined relative to a time zero, the time zero corresponding to the determination that sensor data corresponding to the rotational speed of the shaft exceeding the threshold rotational speed; and
transmitting the plurality of time sampled sensor data to a remote processing device configured to store the plurality of time sampled sensor data relative to the time zero in a time zero data structure, wherein the time zero data structure is configured to correspond to a unique identifier of the motor.
