Drum Motor

Installation

All Drum Motors are stamped at one shaft end with the serial number and in

some cases with the letters UP.

Mounting the Drum Motor

with mounting brackets

The mounting brackets must be strong enough to withstand the torque produced

by the motor.

¾ Fix the mounting brackets securely to the conveyor or machine frame.

Ensure that the Drum Motor is fitted parallel to the idler pulley and at right

angles to the conveyor frame.

¾ Insert the shaft ends of the Drum Motor into the mounting bracket according to

the diagram "Mounting orientation" (see above).

¾ If it is necessary to fix the shaft to the mounting brackets, fix it only on one

side so that the opposite side allows axial movement for thermal expansion.

Torque fixing for S-, D-series, 80i, 113i, 217i and 315i: fix non-cable side

Torque fixing for 138i, 165i, 216i and 113E: fix cable side

¾ Ensure that at least 80 % of the Drum Motor shaft flat lengths are supported

by the mounting bracket.

¾ Ensure that the clearance between the flats and the mounting bracket is not

more than 0.4 mm.

¾ If the Drum Motor will be used with frequent reversible operations or many

start/stops: Ensure that there is no clearance between the flats and the

mounting bracket.

Risk of damage to the motor due to wrong mounting

orientation

¾ Ensure that the serial number and/or the UP mark is

situated according to the following installation diagram.

Models 80S, 113S, and D-series can be mounted in any

orientation.

Hint

It is also possible to mount the Drum Motor without mounting brackets. In this

case, the shaft ends have to be fitted into cut-outs that are cut into the conveyor

frame and reinforced to fulfill the above requirements.
