Magnetically enhanced oil filter apparatus

Abstract

A DC motor apparatus includes a motor housing assembly which includes an outer liquid-tight coolant chamber and an inner, armature-reception chamber portion. Pairs of permanent magnet stator magnet modules are housed within the liquid-tight coolant chamber, and shunt members are housed within the liquid-tight coolant chamber between the stator magnet modules. An armature is centrally located in the inner, armature-reception chamber portion. The armature includes at least one pair of armature pole portions which are wound with same-directional windings. A commutator is connected to the armature, and the commutator includes commutator contacts. An adjustable brush advance / retard mechanism includes roller brushes for contacting the commutator contacts. A liquid cooling system includes a coolant pump and a coolant fluid radiator for circulating liquid coolant through the liquid-tight coolant chamber for cooling the stator magnet modules and the shunt members.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates generally to direct current (DC) electric motors and, more particularly, to DC electric motors with motor-cooling features. [0003] 2. Description of the Prior Art [0004] It is well known that DC electric motors give off heat when they operate. With many motors, ambient air is sufficient for cooling the motors. Even a fan blowing ambient air may also provide sufficient cooling. However, for a DC electric motor that performs relatively large amounts of work and generates more heat than can be sufficiently cooled merely by air, it would be desirable if a DC electric motor were provided with a liquid cooling system. [0005] Generally, a conventional DC electric motor has a simple stator, an armature that includes a pair of armature poles wherein one armature pole has a right-handed winding, and the other armature pole has a left-handed winding. Also, such a conventional DC electric motor inc...

AI Technical Summary

Benefits of technology

"The present invention provides a DC motor apparatus with improved efficiency and performance. The motor includes a housing assembly with stator magnet modules and shunt members. The stator magnet modules have multiple pairs of magnets and the shunt members are positioned between the stator magnet modules. The shunt members have same-directional windings that match the magnets. The motor also includes a brush advance / retard mechanism and a roller brush support plate for adjusting the position of the brushes against the commutator contacts. The motor housing assembly includes an outer liquid-tight coolant chamber and the inner armature-reception chamber portion between the stator magnet modules. The shunt members can include at least one north-pole to north-pole or south-pole to south-pole shunt member, and the same-directional windings can include right-handed or left-handed windings. The motor housing assembly also includes a plate drive assembly for adjusting the roller brush support plate. The stator magnet modules have a plurality of cylindrical magnets and shunt blocks. The shunt carrier blocks are connected between the magnets and the shunt members to ensure proper alignment and performance. The motor can provide maximum torque and performance at different motor speeds and loads. The motor can also include a liquid coolant system and a pump-to-radiator conduit for improved cooling."
