Abstract
The motor protector for a motor is located so as to be responsive to the discharge temperature of a compressor. The protector is thereby responsive to motor current and compressor discharge temperature. Additionally, by conduction, the protector is responsive to the motor temperature. For scroll compressors, specifically, this provides protection from excess heating of the scroll wraps without requiring an additional sensor.
