However, regardless of the motor or solution (four), it is based on Wei as the source of power, using the magnetic field account to achieve the power of the mechanical work to generate power, or to sense the re-energization of the magnetic field to produce the corresponding vibration towel s § change signal However, the above-mentioned technical content for synchronizing and analyzing the rotational angle of the motor so that the angling is connected in series with the rotary motor can achieve the purpose of synchronous analysis, but the derivative is derived from the accuracy of the analysis. (4) Magnetic interference (Lion)瞧 的 c interference)' Especially for the resolver with higher resolution requirements, the interference caused by the voltage generated by the magnetic field and the conductor will become more significant. Eight bodies. In the US Patent No. 6856() No. 61, the specific technology (4) of the revolver is set on the rotating shaft of the internal-rotating direct-drive motor, and the technical content is in compliance with (4) Green The basic requirements, bribery Xiao Ma __ (four) move, to obtain the position information of the synchronization angle, the manufacturing is still not ideal, especially in the case of avoiding the motor action, the interference caused by the angle reduction, the US patent case will be due to Interpretation of the motor room = from the Qi, the offer, the material-specific deletion and the conventional technology ~ the structure of the complex structure - in addition to the production of the 4 degree of the arbitrarily, while also on the 3 due to the content of the turbulence makes the motor in the axial direction can withstand The low effect on the use of the direct drive motor will be more significant. [New content] Therefore, the main purpose of this creation is to provide a motor structure with a resolver, which is a bearing structure necessary for Lin Chengzhong, which is installed in the motor unit and the angler unit. The X-expanded handle reaches a single-pass and the eliminator unit to reduce the possible interference, and at the same time, the set wheel supports an appropriate barrier between the motor unit and the resolver unit, and the grounding is effective to reduce interference. The specific effect. The purpose of this creation is to provide a motor construction with a resolver' that is compact in construction and long: the load capacity of the motor in the axial direction. The edge is 'to achieve the above purpose, the motor structure provided with the resolver provided by the present invention includes a motor-unit having a mandrel, an annular casing _ put on the mandrel, and The inner side of the mandrel has a radially outer side, and the inner side of the outer ring surface is opposite to each other and is mutually branched. The stator portion and the rotor portion are respectively disposed on the opposite end of the mandrel and the outer casing; a weaving unit, located at one end of the heart; a bearing portion having a ring-shaped bearing socket, which is formed between the _nuclear opposing toroids and a stator of the hetero-angle H unit without a horse element The ship rotor (four), the bearing, is accommodated in the bearing socket. [Embodiment] Hereinafter, as shown in the first to third figures, a motor structure (10) having a (four) H is provided in a preferred embodiment of the present invention, and the main body includes a motor unit (20). ), a resolver unit (3〇) and a bearing unit (4〇). The motor unit (20) is externally rotated, and has a hollow mandrel (21), an annular outer casing (22) having an inner diameter larger than the outer diameter of the mandrel (21), and the piercing shaft is sleeved in the core The shaft (21) and the radial annulus on the inner side of the outer cymbal (22) and the radial annulus on the outer side of the mandrel (21) face each other and are spaced apart from each other, and a certain sub-portion (23) Surrounding the bottom end of the outer ring surface of the mandrel (21), the rotor portion (24) surrounds the bottom end portion of the inner ring surface of the outer casing (22). 23) Relatively moving by magnetic force, it is easy to say that the function of the motor unit (20) is the same as that disclosed in the conventional motor technology. The angler unit (30) is also a sensing technique for resolving angular positions, and has an angled stator (31) and an angled rotor (32), wherein the angled stator (31) is borrowed A tubular solid seat (33) is coaxially fixed to the axial top end of the mandrel (21), and the angled rotor (5) is fixed on the top end of the inner ring surface of the outer casing (22), and The angled stator (31) adjacently corresponds to 'turning the angled rotor (32) synchronously with the rotor portion (23) via the outer casing (22), whereby the corner of the motor unit (2〇) The location is parsed. The miscellaneous portion (40) has an annular bearing height (41) between the mandrel (21) and the outer casing (22), and the stator portion of the aging unit (10) _ motor unit (2G) Between the rotor portions (23) (24), the vehicle is housed in the pumping socket (9), and the motor single a (20) and the recoiler unit (3) are allowed. Rotation, wherein the bearing away from (4) is the accommodation space defined by the specific configuration between the outer casing and the car (22) (21), specifically: the casing (22) The annular body (221) having an appropriate thickness, the axon outer ring protrusion (222) axon is disposed on the ankle ring surface of the (4) (221), and the outer pressure ring (223) is coaxial Radially projectingly fixed to the bottom side wall of the outer ring protrusion (222) and spaced apart from the convex step (2221) on the side of the outer ring protrusion M437572, and forming a groove shape therebetween The collar (224); the mandrel (21) has a hollow tubular reduction (211), and the inner ring protrusion (212) of the first shape is coaxially protruded from the surface of the body (211), and is mixed with the material. The cymbal (222) is opposed to each other, and the inner pressure ring (213) is coaxially and radially protrudedly fixed on the top side body wall of the inner ring protrusion (212) The sub-phase is spaced apart from the convex step (2121) on the bottom side of the inner ring protrusion (212), and a groove-shaped inner ring recess (214) is formed therebetween; «the inner concave (214) and the outer ring concave The (224) portions are opposed to each other by the opening, and the bearing pockets (41) are formed between them. By the composition of the above components, the motor structure (i〇) having the resolver is spatially separated by the bearing portion (40) as the decanter unit (3〇) and the motor unit (10). The structure & can expand the distance between one, reduce the interference degree of the motor unit (2〇) to the resolver unit, and at the same time, by the barrier of the bearing (42), The interference of the motor unit (20) can be further solved, and the interference prevention effect can be achieved.
