Embodiment Construction

[0018] Example embodiments will now be described in more detail with reference to the accompanying drawings.

[0019] refer to figure 1 A scroll compressor 10 includes a cylindrical housing 12 and a single-phase motor 40 configured to drive an orbiting scroll member 52 using a drive shaft 30 . The motor 40 may be, for example, a single-phase induction motor. Alternatively, the motor may be a synchronous motor. Furthermore, the motor 40 may be a multi-phase motor, such as a three-phase motor.

[0020] Electric motor 40 includes a stator assembly 42 , windings 44 wound around stator assembly 42 , and a rotor 43 coupled to drive shaft 30 . Specifically, winding 44 is formed by looping wire about teeth within stator assembly 42 .

[0021] As described herein, the wire used for winding 44 includes aluminum. Additionally, as used herein, aluminum should be understood to also include suitable aluminum alloys used as wires to form the motor windings 44 .

Abstract

A compressor is provided and includes a single-phase electric motor and a protector device. The electric motor drives a compression mechanism and has a rotor and a stator. The stator is comprised of aluminum windings. The protector device is attached to the stator and is configured to disconnect the electric motor from a power supply when an input voltage of the power supply to the electric motor is less than a threshold voltage value set at a level between a minimum run voltage and an overheat voltage of the compressor. The overheat voltage corresponds to an overheat temperature of the electric motor. The threshold voltage value is set at a level that is between the minimum run voltage and the overheat voltage. The protector device includes a tolerance level such that the threshold voltage minus the tolerance level is greater than the overheat voltage and the threshold voltage plus the tolerance level is less than the minimum run voltage.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Provisional Application No. 61 / 791,330, filed March 15, 2013. The entire disclosure of this application is incorporated herein by reference. technical field [0003] The present disclosure relates to compressor motors, and more particularly to systems and methods for protecting compressors with aluminum winding motors. Background technique [0004] This section provides background information related to the present disclosure which is not necessarily prior art. [0005] Refrigeration and air conditioning systems generally include a compressor, a condenser, an expansion valve or its equivalent, and an evaporator. These components are coupled sequentially to define a continuous flow channel. Refrigerant flows through the system and alternates between liquid and vapor or vapor phases. The various types of compressors used in refrigeration systems include, but are not limited t...
