Hard to tell with that photo as the tiny piece is a bit blurred but it may be one of the Hall sensors - these are attached to a PCB via 4 or more leads or a strip with solder pads differing depending on motor type - Nippon Densan or Pioneer and are fitted into the periphery of the motor board. You’ll need to dismantle the motor fully and have a good look. If you’ve lost a sensor the motor won’t run - you can’t just glue them back as they are an electronic component soldered in place and control the motor.
