8.2.2 Installing the motor with mounting brackets
Themountingbracketsmustbesucientlyrobusttowithstandthemotortorque.
1. 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.
2. Insert the shaft ends of the drum motor into the mounting brackets according to the „Mounting position” table
(see above).
3. If the shaft 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drummotoratsareheldbythemountingbrackets.
5. Ensurethatthedistancebetweentheatsandthebracketisnotmorethan0.4mm.
6. If the drum motor is used for frequent reversing duty or for start/stop operation: Ensure that there is no gap
between key surfaces and the mounting brackets.
The drum motor can also be installed without mounting brackets. In this case, the shaft ends must be
installedintocorrespondingrecessesintheconveyorframe;theserecessesmustbereinforcedinsuchaway
that they meet the aforementioned requirements.
