Dry condition
BiS series is an electric component. It may be damaged by liquid like
water and oil. Therefore keep away from them. If the air is supplied
into a spindle, take some structure not to catch condensed dew. Even
if the air is dried, dew condensation may occur by the effect of the
adiabatic expansion. Therefore be care enough. If dew condensation
happens in motor, trouble may occur.
Keep the manufacturing number
Write down and remember the serial number on the lead wire of stator,
and the manufacturing number on the side of rotor, so that you can
find the manufacturing number of the motor when the maintenance.
Check resistance and insulation
Before assembling a spindle, check the resistance and insulation of
winding. And also check them on periodically maintenance.
WARNING
Shutdown the power supply and disconnect the
leads which are connected to the amplifier before
measuring to prevent an electric shock. In
measuring, insulate the open terminals so that not
to touch.
Winding resistance
Measure the winding resistance by milli-ohm meter according to the
following list. Insulate the terminals that are not used while
measuring.
