Thermal aspects
The dissipation of the device is the sum of two sources:
the supply current (I
plus the motor current ( I
voltage (V
(I
is not running. It is obvious from the ratings that the
combination of V
allowed at T
note 2. But it is also improbable that the motor is
continuously driven, therefore the following assumptions
have been made.

It is assumed that the device must be capable of moving
the motor from one end to the other in four equal steps and
that the total time needed for this excursion is 16 seconds.
After this excursion a pause is allowed before the same
pulses are used to return to the original position.
This operation is illustrated in Fig.11.
