In order to perform maintenance on the rotor, it is necessary to partly disassemble the motor. This is done in two steps. First, apply the bearing puller and remove the bearing ring. Second, apply the rotor puller and pull out the rotor from the stator housing in a safe way, as described below.

The bearing puller, crafted in alloy and aluminum, is developed and manufactured by Copenhagen Subsea A/S. The bearing puller is customized for our subsea thruster and must be applied as part of the maintenance process. The bearing puller is purchased as an additional product.
