If the resistance is lower than 1 Giga-ohm the
windings should be dried in one of the two following
ways:
1) Bake in oven at temperatures not exceeding
90 ⁰C until insulation resistance becomes
constant.
2) With rotor locked, apply low voltage, and
gradually increase current through windings
until temperature measured with thermometer
reaches 90 ⁰C. Do not exceed this
temperature.
If the motor is stored for an extensive period, the rotor
must be periodically rotated. In case the ambient
conditions are very humid, periodical inspection is
recommended during storage.
When storing the motor, please ensure that the motor
is covered, so as not to permit any metal particles or
dust to collect inside the motor. This is especially
important when dealing with either the air (AC) or
combined (CC) cooled motor.
1.9. Handling
Raising and moving of the motors should be steady
and jointless, otherwise bearings may be harmed.
Motor connectors, moving parts or cables, should not
be used to lift the motor. The motor should be lifted
by a sling around the rotor, or via an X-bracket
attached to it. Take care, not to damage the sensors
or connectors during manipulation.
