The mounting brackets must be sufficiently robust to withstand the motor torque.
4
Install the brackets at the conveyor or machine frame. Ensure that the drum motor
is installed parallel to the idler pulley and at a right angle to the conveyor frame.
4
Insert the axle ends of the drum motor into the mounting brackets according to the
"Mounting position" table (see above).
4
If the axle must be fastened to the mounting brackets (e.g. with a screw through a cross hole
in the journal), it should be done only on one side so that the other side can move in axial
direction in case of thermal expansion.
4
Ensure that at least 80% of the key surfaces of the drum motor are held by the
mounting brackets.
4
Ensure that the distance between the key surfaces and the bracket is not more than 0.4 mm.
