1.2.7 Ambient Environment
If you continue to use the spindle motor with dirt such as oil mist and dust adhered, its cooling performance degrades
and the motor is unable to fully exercise its performance, which may cause the spindle motor overheat alarm. In some
cases this may result in damage to the bearing or cooling fan. Use a filter, etc. to protect the motor from oil mist and dust.
1.2.8 Installation of Spindle Motor
Make sure that the spindle motor is installed so that the motor shaft points from downward to 90° as shown below. When
installing upward more than 90°, contact your Mitsubishi Electric dealer.
To yield good cooling performance, provide a space of at least 30mm
between the cooling fan and wall. If the motor is covered by a structure and
the air is not exchanged, its cooling performance degrades and the motor is
unable to fully exercise its performance, which may cause the spindle
motor overheat alarm. Do not use the spindle motor in an enclosed space
with little ventilation.
CAUTION
1. Rubber packing for waterproof is attached on the inner surface of the top cover of terminal block, and on the fan lead.
After checking that the packing is installed, install the top cover so that no foreign objects are stuck in between.
2. When installing a motor on a flange, chamfer(C1) the part of flange that touches inside low part of the motor.
