  • Patent number: 11489397
    Abstract: A drive device includes a drive unit having an annular shaped adhesion recess portion, a cover including an annular shaped adhesion protrusion portion that faces the adhesion recess portion, an adhesive sealant that adheres the adhesion recess portion to the adhesion protrusion portion, and a spacer that maintains a distance between the adhesion recess portion and the adhesion protrusion portion. Therefore, it is possible to ensure that a space is formed between the adhesion recess portion and the adhesion protrusion portion, and adhesive sealant is able to enter this space. As a result, it is easier to ensure that the adhesion recess portion and the adhesion protrusion portion are bonded in a stable manner by the adhesive sealant. Therefore, it is possible to provide a drive device in which components are appropriately adhered and fixed to each other.

  • Patent number: 11370476
    Abstract: A drive device includes a motor, a control board, a connector located between the motor and the control board in a predetermined direction, and a solder connecting a motor wire and the control board. The control board has a through-hole opening on an upper side and on a lower side. The connector includes a support portion that protrudes toward the control board such that a tip surface of the support portion is in contact with the lower side of the control board, a guide portion that has a guide hole through which the motor wire passes, the guide hole opening on a lower side and on an upper side. The upper side of the connector is spaced from the lower side of the control board in the predetermined direction. A fillet of the solder is formed on both the upper side and the lower side of the control board.

  • Patent number: 11349371
    Abstract: A drive device includes a motor, a connector on which a control board is mounted, and a cover that defines a housing space for the control board together with the motor and the connector. A first recess formed on a first side of the motor and having an annular shape is connected by a first adhesive to a first protrusion formed on a mounting side of the connector. A second recess formed on a connection side of the connector and having an annular shape is connected by a second adhesive to a second protrusion formed on a rim side of the cover.

  • Patent number: 11050318
    Abstract: A drive device includes: a cover that is installed to an outer wall of a housing; a control unit that is installed in an inside of the cover; a terminal that extends from the control unit and extends through the cover; and a lead wire that extends from a coil and extends through the housing and the cover. The lead wire is electrically connected to the terminal at an outside of the cover. Therefore, the lead wire and the terminal can be connected together after installation of the cover to the housing. At this time, a lead wire insertion hole is shielded by the cover, and thereby it is possible to limit intrusion of solder debris into an inside of the housing through the lead wire insertion hole.

  • Patent number: 10756593
    Abstract: A drive apparatus is provided which includes a motor and a control unit. The control unit has a heat sink secured to a cover. The motor is equipped with leads extending toward the control unit through a housing. The control unit has a substrate which is equipped with connectors detachably joined to the leads, thereby eliminating soldering or welding to achieve an electrical connection of the motor and the control unit. Such a connection is accomplished by inserting the leads into the connectors, thus eliminating the need for a special and large-sized equipment and resulting in a decrease in production cost of the drive apparatus. The non-destructive disassembling of the motor and the control unit is achieved by disengaging them from each other to remove the second terminal from the first terminal.

  • Patent number: 10251215
    Abstract: A control device includes an AC-DC converter that converts power supplied from a commercial power source into DC, a DC-DC converter that supplies the DC to a fixing heater, an calculator that calculates a target DC voltage of the DC to be supplied to the fixing heater, based on detected temperature of the fixing heater, an overcurrent detection unit that outputs an interruption signal when an overcurrent detection value is detected in a circuit including a switching element, and a controller that calculates switching time for switching the switching element so that an output of the DC-DC converter reaches the target DC voltage. When the interruption signal is output causing stopping of the switching of the switching element, the controller causes the calculator not to calculate the switching time to continuously use the previously calculated switching time after resuming switching of the switching element at a next switching cycle.
