Nikhil R. LAKHKAR has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20240034154
    Abstract: A magnetic HVIL system for a drive in a transport application includes a Hall effect sensor within at least one housing of the drive that includes terminals and a removable cover. The removable cover includes a magnet having a magnetic field that is detectable by the Hall effect sensor when the removable cover is installed on the housing. The magnetic field of the magnet is not detectable by the Hall effect sensor when the removable cover is removed from the housing. The magnet HVIL system is configured to be operable to enable active operation of the drive when the Hall effect sensor detects the magnetic field of the magnet and is in a closed circuit condition and disable operation of the drive when the Hall effect sensor does not detect the magnetic field of the magnet and is in an open circuit condition.

  • Patent number: 11706899
    Abstract: A compressor may include a compressor shell, a motor, a compression mechanism, an enclosure, a control module, a fan, and an airflow deflector. The compression mechanism is disposed within the compressor shell. The motor drives the compression mechanism. The enclosure defines an internal cavity. The control module is in communication with the motor and is configured to control operation of the motor. The fan may be disposed within the internal cavity. The airflow deflector may include a base portion, a first leg, and a second leg. The first and second legs may be spaced apart from each other and may extend from the base portion. The fan may force air against the base portion. A first portion of the air may flow from the base portion along the first leg, and a second portion of the air may flow from the base portion along the second leg.

  • Publication number: 20230146546
    Abstract: In other features, a refrigeration system is provided and includes a compressor motor, an inverter, a converter and a control module. The inverter is configured to convert a direct current (DC) bus voltage to an alternating current (AC) voltage and supply the AC voltage to the compressor motor. The converter is configured to convert a DC input voltage to the DC bus voltage. The control module is configured to obtain a parameter and in response to the parameter exceeding a predetermined threshold, reduce the DC bus voltage and at least one of (i) reduce a switching frequency, (ii) increase an amount of negative d-axis current of the compressor motor, or (iii) reduce a speed of the compressor motor.

  • Publication number: 20220104391
    Abstract: A compressor may include a compressor shell, a motor, a compression mechanism, an enclosure, a control module, a fan, and an airflow deflector. The compression mechanism is disposed within the compressor shell. The motor drives the compression mechanism. The enclosure defines an internal cavity. The control module is in communication with the motor and is configured to control operation of the motor. The fan may be disposed within the internal cavity. The airflow deflector may include a base portion, a first leg, and a second leg. The first and second legs may be spaced apart from each other and may extend from the base portion. The fan may force air against the base portion. A first portion of the air may flow from the base portion along the first leg, and a second portion of the air may flow from the base portion along the second leg.

  • Patent number: 11206743
    Abstract: A compressor may include a compressor shell, a motor, a compression mechanism, and an assembly that houses an electronic component. The electronic component may control operation of the compressor and/or diagnose compressor faults. The assembly may include a shell, an electronic component, a fan, and an airflow deflector. The shell member may define an enclosure having an internal cavity. The fan and the electronic component may be disposed within the internal cavity. The airflow deflector may include a base portion, a first leg, and a second leg. The first and second legs may be spaced apart from each other and extend from the base portion. The fan may force air against the base portion. A first portion of the air may flow from the base portion along the first leg. A second portion of the air may flow from the base portion along the second leg.
