An automotive manufacturer of an ADA (American Disabilities Act) compliant vehicle ramp needed a motor to enable someone in a wheelchair to easily enter and exit the vehicle. It was critical that the ramp have a zero-failure rate with a manual override option since the ramp comes out of the floor and lowers to the ground, allowing wheelchairs to have a smooth transition from the ground onto the ramp and into the vehicle. In order to accurately position the height of the ramp, Groschopp added a two channel encoder to send feedback to the motor.
