Assembly of electric motor starter components

Abstract

The invention relates to assembly of electric motor starter components. Techniques disclosed herein include systems and methods for assembly of electric motor starter connecting packages that enable increased automation and reduced assembly via top-down assembly of circuit components, thereby allowing robotic placement, connection, and securing of circuit components. The connecting package can include an electric motor starter, with optional overload protector, packaged as one unit. The motor starter can include an electrical circuit containing a triac, current transformer, Positive Temperature Coefficient (PTC) element, resistor, and a capacitor. A cover and base of the connecting package enclose and firmly secure connected circuit elements without needing a circuit board or filler material. The device design enables quick testing of the motor starter circuit and circuit elements after being enclosed by the housing.

Description

technical field [0001] The present disclosure relates to electric motor starters, and more particularly to electric motor starters and connection packs for compressors such as gas compressors and refrigerator compressors. Background technique [0002] Electric motors used with cooling compressors or refrigerator compressors are usually powered or controlled by a motor starter. Generally, a motor starter device and an overload protector are installed outside the refrigerator compressor or outside the housing of the refrigerator compressor. The motor starter itself usually has a housing and terminals for connecting to the refrigerator compressor. As such, motor starters are typically manufactured separately from refrigerator compressors. The housing of a motor starter may contain various circuit components such as capacitors and positive temperature coefficient (PTC) elements. [0003] Motor starter connection packs are routinely manufactured as high volume, low cost device...

AI Technical Summary

Problems solved by technology

The act of adding filler material and / or mechanically encapsulating circuit components can physically shock or move circuit components, which can lead to defective devices

However, testing equipment after encapsulating a motor starter can increase assembly and testing time due to some electrical testing that makes certain components heat, resulting in the need to wait for the heat-generating components to cool down before completing the electrical testing, therefore, after covering circuit components This test is challenging
