contact surfaces of the primary and secondary parts are combined with a
highly heat-dissipating machine construction.
In this connection, please observe that an increased heat introduction into
the machine construction has a negative impact on the achievable accuracy.
During design of a system with maximum accuracy, the operating tempera‐
ture of the motor winding is decisive.
With increasing winding temperature, the emitted heat of the machine is also
increased. If the temperature level of the machine has to be kept at a con‐
stant level, the motor should be sufficiently dimensioned or equipped with
machine-side cooling.
If the contact surfaces of the motor components, particularly of
the primary part, are made of a material with low heat conductivity
(e.g. plastic), a reduction in motor performance has to be expec‐
ted.
In general, the heat dissipation must be increased proportionally
with the size and frame length and the respectively higher power
loss of the motor if the same utilization capacity of the motor is to
be achieved.
For this reason, observe maximum heat dissipation of motor com‐
ponents when designing the machine. Only this way optimum dis‐
sipation of the emitted heat of the motor via the surrounding ma‐
chine components can be ensured.
The following specifications serve as reference to estimate the required mo‐
tor performance data depending on the thermal connection of the motor. The
illustrated installation modes can be selected and taken into account for mo‐
tor controller dimensioning in IndraSize and for commissioning in IndraWorks.
