The present disclosure relates to a bearing sealing member, a bearing sealing assembly, and a bearing assembly. The bearing sealing assembly comprises: a frame, a radial outer end face of the frame being provided with a wave recess extending in a circumferential direction; a sealing body, the sealing body being attached to an outer wall of the frame; and a felt material, the felt material being filled in the wave recess of the frame and protruding out of a wave crest of the wave recess in the radial direction.

A radial outer wave structure of a sealing head is filled and covered with the felt material, and the felt has good air permeability and waterproofness. This means that, while moisture and pollutants are prevented from entering the bearing, an appropriate amount of gas exchange between the interior of the bearing and the external environment is permitted, thereby effectively eliminating a possible vacuum state in a bearing cavity during a temperature change process, maintaining a pressure balance between the inner air and the outer air of the bearing, relieving abrasion of a sealing lip, and prolonging the service life of the sealing assembly.

An electric oil pump, comprising a drive electric motor (10), a pump rotor assembly (20) and a housing (30), wherein the drive electric motor (10) and the pump rotor assembly (20) are mounted inside the housing (30); the drive electric motor (10) comprises a rotor (12) and an electric motor shaft (13), which are coaxially connected in an anti-torsion manner; and the rotor (12) and the pump rotor assembly (20) are axially spaced apart, and the electric motor shaft (13) axially runs through the rotor (12) and the pump rotor assembly (20) in sequence. The electric oil pump further comprises a first bearing (40). The electric motor shaft (13) comprises a first end (13a) which axially faces away from the rotor (12) and extends out from the pump rotor assembly (20), and the first end (13a) is rotatably supported on the housing (30) by means of the first bearing (40). The electric oil pump can be reduced in size, thereby facilitating installation, and being stable and reliable.

Abrégé

The invention relates to a method for the open-/closed-loop controlling of a stepper motor. The stator windings of the stepper motor are controlled via a full-bridge circuit with switching elements. The switching elements can be controlled in such a way that a rapid-decay mode or a slow-decay mode can be set. A charge cycle time in a pulse width modulation (PWM) period is stored, and the rapid-decay mode or the slow-decay mode for the next PWM period is set according to the charge cycle time. The invention additionally relates to a control unit, and a stepper motor comprising the full-bridge circuit and the control unit.
