HYDRAULIC POWER STEERING PUMP HAVING WET TYPE MOTOR WITH OPEN TYPE MAGNET

摘要

PURPOSE: A steering pump including a wet motor of an open magnetic structure is provided to improve efficiency of a motor by improving magnetic properties of a permanent magnet and to improve economic efficiency by simplifying a structure to connect the permanent magnet. CONSTITUTION: A steering pump (100) including a wet motor of an open magnetic structure comprises a housing (110), a gear pump module (130), and a motor module. The gear pump module pressurizes fluid by being supported on one side of the housing. The motor module supplies driving power to the gear pump module by being supported to the other side of the housing and includes a stator and a rotor. The stator is supported by the housing so that a current is supplied by a power source applied in the outside. The rotor is connected to a partition member of the housing and includes a permanent magnet (161) and a motor rotary shaft (151). The outside of the permanent magnet includes an exposed unit (161a) exposed towards the stator.
