Upon testing, the initial version of the motor mounting bracket had a problem where it would slowly slide towards the motor as it was being run. It also was susceptible to deformation under high torque from the motor.
To solve the problem, I used Solidworks simulation tools to determine what kind of reinforcement structure would best eliminate both sliding and deformation. The best solution to the problem turned out to be a simple L-Channel Bracket that would physically prevent the motor from sliding, while at the same time providing more resistance to the torque of the motor.
