  In a driver-integrated motor that has been conventionally proposed, the case of the driver unit is entirely made of a metal material in order to dissipate heat generated in the driver unit. For this reason, there is a problem that the overall weight increases. Conventionally, an active structure for releasing heat generated from an electric component (transistor switch) disposed inside the case to the outside through a metal case has not been adopted. Therefore, there has been a limit to increasing the excitation current in order to increase the motor torque. Further, the structure for arranging the circuit board on which the drive circuit is mounted in the case is complicated, and the assembly of the driver unit is troublesome.

  An object of the present invention is to provide a driver-integrated motor including a driver unit that is lighter and has a higher heat dissipation performance than conventional ones.

  Another object of the present invention is to provide a driver-integrated motor that can be easily assembled.

  Still another object of the present invention is to provide a driver-integrated motor capable of preventing heat from an electrical component with a large amount of heat disposed in a driver unit from adversely affecting an electrical component with a small amount of heat. There is to do.

  Another object of the present invention is to provide a driver-integrated motor in which the connector part of the wire harness does not come off even when a pulling force is applied to the wire harness.

  Another object of the present invention is to provide a driver-integrated motor in which electrical adjustment of a drive circuit after assembly is easy.

  Still another object of the present invention is to provide a driver integrated motor capable of knowing the operating state of a drive circuit from the outside.

  A driver integrated motor to be improved by the present invention includes a motor unit and a driver unit. The driver unit includes a drive circuit that controls driving of the motor unit, and is combined with the motor unit via a coupling structure. The driver unit has a structure in which a circuit board used for configuring a drive circuit, an electric component with a small amount of heat generated on the circuit board, and an electric component with a large amount of heat generated are housed in the case. have. An electrical component that generates a large amount of heat is generally a semiconductor switching element for driving. In the present invention, the case of the driver unit has a structure in which the heat radiating portion and the case main body portion are combined. The heat dissipating part is formed of a material with excellent heat conductivity having a heat sink function to which an electrical component having a large amount of heat is mounted. Generally, the heat radiating part can be formed by extrusion molding or the like using a metal material such as aluminum or copper. The case body has a structure in which a circuit board formed of a synthetic resin material and mounted with electrical components with a small amount of heat generation is accommodated. Needless to say, the synthetic resin material used to form the case main body may include a reinforcing material such as glass fiber or glass particles.

  According to the present invention, heat from an electric component with a large calorific value mounted on the heat radiating part can be directly radiated from the heat radiating part to the outside. Further, since the case main body is formed of a synthetic resin material, the case of the driver unit can be made lighter than before, and the weight of the entire driver integrated unit can be made lighter than before. Further, when the case of the driver unit is divided into a heat radiating portion and a case main body portion, it is easy to mount an electrical component with a large amount of heat generation on the heat radiating portion, and it is easy to store the circuit board in the case.

  A lead wire may be used for electrical connection between an electrical component having a large amount of heat generated in the heat radiating portion and a circuit pattern on the circuit board. However, if the electrical components and circuit boards that generate a large amount of heat are connected via a connection structure that is mechanically and electrically connected when the heat dissipation part is mounted on the case body, the driver unit Easy to assemble. In this case, the electrical component having a large calorific value has a structure including a plurality of male connection terminals. In general, an electrical component that generates a large amount of heat may be integrated into an IC (integrated circuit). The circuit board is also provided with a plurality of female connection terminals that are press-fitted with a plurality of male connection terminals (which can be tightly fitted to complete electrical connection simultaneously). A connection structure can be constituted by a plurality of male connection terminals and a plurality of female connection terminals. With such a connection structure, the electrical connection and the mechanical connection can be completed only by inserting a plurality of male connection terminals into the plurality of female connection terminals. Assembling becomes easy.

  In addition, radiation between the first component storage chamber in which an electrical component with a large amount of heat generation is stored and the second component storage chamber in which a part of the electrical component with a small amount of heat generation is stored is inside the case body. It is preferable to integrally provide a radiation heat shielding wall portion for preventing heat transfer. By providing such a radiation heat transfer shielding wall, it is possible to prevent direct heating of electrical components with a small amount of heat generation due to radiant heat emitted from electrical components with a large amount of heat generation. A component having a low heat-resistant temperature can be used as the component. As a result, the drive circuit can be made at low cost. In addition, the reliability of the drive circuit can be increased.

  Moreover, the structure of the case body is arbitrary. For example, the case main body portion may have a structure including a circuit board housing chamber for housing a circuit board with a motor unit side opening that opens toward a surface facing the motor unit. In this case, when the circuit board is stored in the board storage chamber with the board surface facing the motor unit side opening, a part of the electrical component with a small amount of heat generation is stored in the second component storage chamber. As described above, an electrical component with a small amount of heat generation is mounted on the circuit board. This facilitates the mounting of the circuit board on which the electrical component is mounted to the case body. If the circuit board is exposed from the opening on the motor unit side, the connector part used for electrically connecting the motor unit and the driver unit via the connector structure is mounted on the circuit board in the same manner as in the past. Thus, the electrical connection between the driver unit and the motor unit can be easily performed.

  The circuit board has a connector portion to which a connector portion of a wire harness having a plurality of lead wires including a power supply line and a connector portion to which these lead wires are electrically connected is connected to the second component storage chamber. Can be implemented to be inserted. The case main body includes a first peripheral wall component surrounding the periphery of the substrate storage chamber, and a second component storage in cooperation with the radiation heat transfer shielding wall formed continuously from the first peripheral wall component. A second peripheral wall component that surrounds the periphery of the chamber, and a first peripheral wall component that is formed continuously with the first peripheral wall component and the second peripheral wall component and that surrounds the first component storage chamber in cooperation with the heat radiating portion. 3 peripheral wall constituent portions, and a bottom wall portion that is formed continuously with the second peripheral wall constituent portions and the third peripheral wall constituent portions and faces the motor unit side opening. When the case body is configured in this way, a through hole through which a connector portion of the wire harness and a plurality of lead wires continuous with the connector portion pass is formed in the bottom wall portion. The second peripheral wall constituent part is formed with a peripheral wall side opening which is closed by a lid member constituting a part of the second peripheral wall constituent part. In addition, the case body is placed at a position facing the opening on the peripheral wall side and contacts the connector part connected to the connector part to prevent the connector part from being tilted by an external force applied to the connector part from the peripheral wall side opening part side. An inclination preventing wall portion may be further provided. Furthermore, the lid member is integrated with a locking prevention engagement part that prevents the connector part from coming out of the connector part when a pulling force is applied to a plurality of lead wires by engaging with a part of the connector part. Can be provided. If it does in this way, since a wire harness can be attached and exchanged in the state where a lid member was opened, a wire harness of arbitrary length can be used according to a use. In addition, the attachment of the lid member completes the removal of the connector portion, so that the wire harness can be easily attached.

  Moreover, it is preferable to arrange | position the adjustment component operated in order to adjust later on the circuit board in the position which can be operated through a surrounding wall side opening part. In this way, after the driver unit and the motor unit are combined, the electric fine adjustment of the drive circuit can be performed, so that the adjustment work on the user side is facilitated.

  In this case, it is preferable that the adjustment component is mounted on the adjustment component mounting board that is mounted upright with respect to the circuit board and is electrically connected to the circuit pattern on the circuit board. When such a structure is employed, the adjustment component can be disposed at a position corresponding to the opening on the peripheral wall side at a low cost and easily.

  In addition, it is preferable to provide a light emitting display means for displaying the operation state of the drive circuit to the outside depending on the presence or absence of light emission. If such a light emitting display means is provided, the operation status of the driver unit can be visually confirmed from the outside, so that maintenance is facilitated. The light emitting display means can be composed of a light emitting element mounted on the adjustment component mounting substrate and a light diffusing member that is provided on the case body and diffuses the light emitted from the light emitting element to the outside. . When such a structure is employed, electrical connection work when providing the light emitting display means can be performed in the process of manufacturing the circuit board, and the assembly of the driver unit is facilitated.

  According to the present invention, since heat generated from an electrical component with a large amount of heat mounted on the heat radiating portion can be directly dissipated from the heat radiating portion to the outside, there is an advantage that the heat radiating performance can be improved as compared with the prior art. Further, since the case main body is formed of a synthetic resin material, the case of the driver unit can be made lighter than before, and the advantage that the weight of the entire driver integrated unit can be made lighter than before can be obtained. In addition, the driver unit case is divided into a heat radiating part and a case body part, so that it is easy to mount electrical components with a large amount of heat to the heat radiating part, and the circuit board can be easily stored in the case. can get.
