The rotation direction of a gear motor is identified by looking at the motor from the front and with the take off shaft turned upwards (see figures below).

Motors with clockwise rotation (D) have a take off shaft which turns clockwise, with the inlet port on the left and the outlet port on the right.

Motors with counterclockwise rotation (S) have a take off shaft which turns counterclockwise, with the inlet port on the right and the outlet port on the left. The figure also shows the pressure flow inside the motors as the oil is transferred from the inlet port to the outlet port. As regards reversible motors (R), the ports are alternatively

for high and low pressure.

Motors with a unidirectional rotation (D or S) have the deno­mination APM. Motors with reversible rotation have the denomination APMR.

It is possible to change the rotation direction of the entire range of motors without having to replace any component, except for the APM100 group, for which it is necessary to replace the front cover.

To ensure a good technical result, we recommend in any case that such inversion be carried out at our factory. Technical descriptions are available on request, which show the correct procedure for the motor rotation inversion.
