DC Motors

Shipping Blocks

Motors supplied with roller bearings at the drive end are shipped with
wooden blocking to prevent axial movement of the shaft during
shipment. Remove the blocking and bolts securing it and discard.
Make sure motor shafts turn freely. If motor is to be reshipped,
blocking of bearing is required.

Motor Application Data

Maximum Safe Speed

The speeds given in

Table C

are the maximum mechanically safe

operating speeds for frames with standard construction. These speeds
must not be exceeded under any condition. Motor control must hold
the maximum speed under any load condition including no-load
within the maximum safe speed. Drive systems whose design
characteristics inherently prevent the AC motor from exceeding the
motor maximum safe operating speed must prevent the motor from
exceeding the maximum safe speed if a single component failure
should occur.

Table C
Maximum Safe Speed

With special construction maximum safe speed may differ from the
above values. In all cases, the maximum safe speed is indicated on the
motor nameplate.

Important: Normal operating speeds must be limited to those listed in

order to meet nameplate rating and assure validity of
warranty.

!

ATTENTION: The machinery builder and/or user are
responsible for assuring that all drive train mechanisms, the
driven machine, and process material are capable of safe
operation at the maximum speed at which the machine will
operate. Failure to observe these precautions could result in
personal injury.
