摘要:
A six lead, two speed, consequent wound, single phase induction motor with a tapped auxiliary winding having a 2-pole high speed mode and 4-pole low speed mode. A portion of the auxiliary winding is connected in series with the four pole main winding. The 4-pole low speed mode has an efficiency of over 80%.

A hermetic motor includes a stator having at least one winding formed by a winding wire, and an on-winding motor protector having at least one contact. To improve the reliability and reduce the cost of the hermetic motor, the winding wire is directly coupled (without a lead wire) to the motor protector contact. Additionally, a common wire extending from the motor protector to a cluster block (if applicable) can be the same type of wire as the winding wire.

An electric terminal connector block is provided with oblong tool openings that communicate with interior channels of the connector block and with openings in the motor wiring electric terminals positioned in each channel of the connector block. The oblong shapes of the tool openings enable insertion of tool pins through the tool openings and openings of the electric terminals and movement of the tool pins along the lengths of the oblong tool openings whereby the tool pins engage with the electric terminals and move the terminals relative to the connector block to insure that the terminals are locked in place in the connector block. In addition, the tooling used with the connector block is operated according to a method that insures that the terminals of the motor winding are moved to a position relative to the connector block where the terminals are locked in place. The tooling also provides conductor bars of a surge testing device that are connected to the electric terminals of the connector block as the terminals are properly positioned in the connector block.
摘要:
A variable capacity compressor assembly (20) configured for variable capacity modulation includes a housing (30), with a compressing mechanism (22) and a driving mechanism (24) disposed within the housing. The compressing mechanism includes compressing members (54, 56) that are shiftable relative to one another between loaded and unloaded states. The driving mechanism includes a line-start brushless permanent magnet motor (26). The line-start brushless permanent magnet motor includes a plurality of permanent magnets (102) that are mounted on, and extend generally axially along, a rotor core body (90) of the motor. Using the motor may reduce manufacture cost, maintain conveniently, and increase reliability.
摘要:
A line-start brushless permanent magnet motor assembly includes an unconventional combination of a rotor assembly including a plurality of permanent magnets mounted thereon, and a stator assembly including aluminum winding coils. The unique combination of construction features leads to significant motor performance enhancements at lower incremental cost. The line-start brushless permanent magnet motor assembly may be incorporated into a hermetic compressor, such as may be used in an air conditioning system, to meet high efficiency standards (e.g., seasonal efficiency energy rating). The disclosed embodiments have an efficiency of at least 90% with winding coils consisting essentially entirely of aluminum.

An electrical connector includes a terminal attached to a length of wiring that extends from the stator windings of an electrical device, and a tubular insulating sleeve that extends along the length of wiring. The sleeve is secured stationary relative to both the wiring and the terminal by being secured to the stator windings by the same mechanical connection that binds the stator windings.
