  • Patent number: 10286345
    Abstract: A fuel filter assembly incorporates a BLDC motor and control circuit configured to operate at a first rotational speed upon startup and switch to a second rotational speed when measured variables indicate that the filter assembly is filled with fuel. The first rotational speed is initiated as a default when power is applied to the control circuit. If the filter assembly has been serviced, it must be primed before resuming normal operation. The first rotational speed is significantly higher than the second rotational speed to reduce the amount of time necessary to prime the filter assembly. The control circuit is arranged to monitor a variable which corresponds to the torque necessary to drive the pump. When the pump is filled with air prior to priming, lower torque is required to drive the pump, which corresponds to lower current draw and power consumption at the BLDC motor.

  • Patent number: 9617986
    Abstract: A hermetic compressor includes: a main bearing (126) which supports a main shaft (120) of a shaft (119); and a thrust ball bearing at an upper end portion of the main bearing (126). A rotor (116) is fixed to the main shaft (120) via a flange. A rotor core (117) has a magnetic center displaced upward relative to the magnetic center of a stator core (115) so that a downward magnetic attractive force is applied between the rotor (116) and the stator (114). Accordingly, a contact load between steel balls and upper and lower races in the thrust ball bearing is appropriately maintained.

  • Patent number: 9572281
    Abstract: A method for controlling a mechanical vibrating element driven by a driving means includes operating the driving means at an operation frequency for stimulating the vibrating element to oscillate at this frequency. The method also includes adjusting the operation frequency of the driving means for stimulating the vibration element at different frequencies and of determining a respective energy consumption of the driving means depending on the frequency at which the vibrating element oscillates. The resonance frequency of the oscillation of the vibrating element is identified as the frequency at which the energy consumption of the driving means is lowest and the driving means for stimulating the vibrating element can be operated at the resonance frequency.
