Motors having spring-loaded
spherical roller bearings must not be
allowed to run at normal speed
without a load. When checking
direction of rotating, do not hold the
switch closed—just “tap” it.
If the direction of rotation is not
correct, reverse it by changing the wiring
connections to the motor. For a three-
phase motor, interchange any two of the
three leads. If the motor is single-phase,
directions for reversing rotation are
given on the nameplate. MARK THE
LEADS TO INDICATE THE
CORRECT CONNECTIONS.
The motor must not be tested for
direction of rotation when coupled to
the pump. If the pump should rotate
in the wrong direction, serious
damage to the pump and motor and
grave injury to nearby personnel
could result.
Once the motor rotation is
confirmed to be correct, make the final
electrical connections to the motor. All
connections must be insulated in
accordance with local electrical codes.
At this time the top drive coupling
can be reinstalled in its original location,
using anti-seize compound on the
registers between the top drive coupling
and the motor rotor.
