Step 2: Connecting motor and pulley
Cut about 2 feet of string to thread into the pulley. Loop around the pulley once and tie a knot that will allow the string to be secured to the internal channel of the pulley.
Lace one end of the thread through the two adjacent holes in the pulley and tie a knot there as shown. This will prevent thread from slipping around the center channel of the pulley and ensure that the pulley winds as it pulls. Double knot is necessary.
Connect the pulley on the mounting hub using the screws and nuts provided with the motor and pulley.
Attach the aluminum bracket, the motor and the mounting hub using the screws provided. Your motor is ready to be attached to the gripper board.
