Patent number: 11569711Abstract: The present disclosure relates to mechanical braking mechanisms used in electric motor applications. The present braking mechanisms may be configured as non-back-drivable mechanical brakes and provide immediate braking of the motors. According to one embodiment, a mechanical brake assembly for an electric motor may include a female disk including a groove and an abutment and a male disk including a projection, the male disk being in mechanical communication with a rotor of the electric motor. When the electric motor is energized, the projection of the male disk is configured to rotate with the rotation of the rotor of the electric motor, but when the electric motor is de-energized, the projection of the male disk is configured to travel within the groove of the female disk and abut the abutment of the female disk, thereby reducing the rotation of the rotor of the electric motor.Type: GrantFiled: July 2, 2020Date of Patent: January 31, 2023Assignee: MOLON MOTOR AND COIL CORPORATIONInventor: Emilio A.

Publication number: 20230009231Abstract: A gear box has a housing and a direct current motor inside of the housing. A rotatable output shaft extends through a wall of the housing and is rotatably driven by the motor via a gear train. The gear box can be used to dispense ice from a refrigerator/freezer. The motor drives the output shaft in one direction to dispense ice cubes. The motor also drives the output shaft in an opposite direction to crush ice and dispense the crushed ice. The gear box has a low-profile height. The gear train is located in front of a motor shaft of the motor and has a maximum height which does not exceed a maximum height of the motor. The motor shaft is perpendicular to the input gear of the gear train and to the output shaft of the gear box.Type: ApplicationFiled: January 21, 2022Publication date: January 12, 2023Applicant: MOLON MOTOR AND COIL CORPORATIONInventors: Emilio A.

Patent number: 10784742Abstract: The present disclosure relates to mechanical braking mechanisms used in electric motor applications. The present braking mechanisms may be configured as non-back-drivable mechanical brakes and provide immediate braking of the motors. According to one embodiment, a mechanical brake assembly for an electric motor may include a female disk having a curved groove and an abutment. The mechanical brake assembly further includes a male disk having a projection, the male disk being attached to a rotor of the electric motor. When the electric motor is energized, the projection of the male disk is allowed to rotate uninterrupted with the rotation of the rotor. However, when the electric motor is de-energized, the projection of the male disk travels within the curved groove of the female disk and abuts the abutment of the female disk, thereby stopping the rotation of the rotor of the electric motor.Type: GrantFiled: October 18, 2018Date of Patent: September 22, 2020Assignee: MOLON MOTOR AND COIL CORPORATIONInventor: Emilio A.

Patent number: 10707721Abstract: The present invention relates to a compact, dual compartment gear motor assembly for use primarily in operating appliances and/or components of appliances. The compact nature of the dual compartment gear motor assembly makes it useful in many residential and commercial appliances, including ice making machines, automatic dishwashing machines, laundry machines and vending machines. The dual compartment configuration separates a gear train assembly and motor into a housing compartment separate from a power source, such as printed circuit board or control board, and further secures the gear motor assembly components within the housing compartments without the need for fasteners.Type: GrantFiled: June 21, 2017Date of Patent: July 7, 2020Assignee: MOLON MOTOR AND COIL CORPORATIONInventors: Emilio A.

Patent number: 10461610Abstract: The present disclosure relates to miniaturized motor assembly for use in an appliance, for example, an ice maker for a commercial or residential refrigerator. The miniaturized motor assembly includes an electric motor, such as a permanent magnet direct current (PMDC) motor, and a printed circuit board operable to control power to the electric motor, wherein the printed circuit board is connected to the motor as a component of the assembly. At least one electrically-conductive connection device acts as a terminal, providing multiple points of contact between the printed circuit board and the motor, forming both an improved, reliable mechanical connection and an effective electrical connection between the circuit board and the motor. Use of the electrically-conductive connection device of the present disclosure eliminates the need for tedious and inconsistent soldering connections, while providing multiple points of contact and improved electrical contact over other forms of connecting devices.Type: GrantFiled: June 5, 2017Date of Patent: October 29, 2019Assignee: MOLON MOTOR & COIL CORPORATIONInventors: Larry Gebhardt, Emilio A.
