  • Compressors and methods for determining optimal parking positions for compressor pistons
    Patent number: 9470225
    Abstract: Compressors and methods for determining optimal parking positions for compressor pistons are provided. A method includes performing a current value evaluation for an initial time during operation of a motor of the compressor. Performing the current value evaluation includes measuring a motor current value at the time and comparing the motor current value to an existing optimal parking current value. Performing the current value evaluation further includes modifying the existing optimal parking current value to the motor current value when the motor current value exceeds or is equal to the existing optimal parking current value.
