NeveRest 40 Motor FEATURES AND TESTING Danny Blau ANDYMARK, INC.
NeveRest 40 Motor Features and Testing 8/27/14 Intro As the AndyMark staff interacted with the FTC community over the past year, we found teams wanted more motor options. This summer we spent a great deal of time looking for and testing new motors that could bring those new options to the FTC community. Our first step was to understand the performance of the FTC motors legal in 2013-14 and the concerns that the community raised about those motors.
NeveRest 40 Motor Features and Testing 8/27/14 NeveRest 40 Testing Test 1: Generating Motor Curves Our first step was to test the existing motors for max power output and max torque. With the data from our motor dynamometer we were able to create an experimental curve for the motor. Each trial consisted of a 20 second build up to the max breaking torque which occurs at the end of the test. The motor started each trial at full speed without any breaking torque applied.

We locked both the motor and output shaft from spinning using the Tetrix motor mount clamp and a motor hub. Using our standard electrical supply each motor was given 12 volts and up to 100 amps.

Gearbox without housing Encoder Attached Encoder One of the most exciting features of the NeveRest 40 is its attached encoder. This is built onto the back side of the motor and runs directly off the motor’s shaft.
