7.4 Coupling of linear servomotors
Linear servomotors can be connected with one another in order to act together on a magnetic track. The
forces of the motors are added together. The motors are connected in parallel to the controller, which leads
to a higher total current. Motors of the same type can always be connected to one another. Motors of
different types but from the same series can be connected together if their power constants are equal.
7.4.1 Temperature sensor
Use the temperature sensor of the motor which has the poorest cooling and which will thus have the higher
temperature development.
7.4.2 Layout of the motors
There is a fixed distance between the motors windings that depends on the series. In the case of the AL2xxx
series this is 16 mm. If linear servomotors are coupled with one another, there must be a multiple of this
winding distance between the windings of the connected motors as well.
Phase repetition = 3 x winding distance = 3 x 16 mm = 48 mm
Example 1 with AL2006 and AL2012
In example 1 the connecting cables of the motors point in different directions. This enables the minimum
distance between the linear servomotors.
