TDK-Lambda, Interface Inc, and Omega Engineering have become our newest Bronze sponsors with donations of parts for a motor dyno I am working on to test the efficiency of our motor and motor controller. We can use this data to make better strategy decisions during the race and to determine if a newer motor is worth the price. The dyno will also be open to other student projects as it provides a motor testing range which is not present in any other MIT lab.
TDK Lambda provided the team with a Genesys 3.3 kW power supply. They has sponsored us with smaller supplies in the past which fills most of our needs, but running the motor a full tilt needs a bit more juice.
Interface has donated a 20Nm torque transducer for measuring torque directly in the output shaft of the motor. This allows for an accurate measurement without other losses affecting the results.
Information is useless without an accurate way to collect it. This 24 bit USB data acquisition module will monitor 16 analog signals ranging from +_ .078V to +- 20V at a 1kHz aggregate sample rate. It also has 500V isolation for peace of mind when plugging in your expensive (from a student perspective) personal laptop!
