Abstract

The invention relates to a construction device for a motor start-up system, comprising a base body (10) with a shell cover (20) arranged on, wherein, the external plane (11) of the base body (10) is provided with a convex ram (12), a pair of first open holes (13) for arranging the corresponding terminal of a capacitor (2) to be connected with the convex ram (12), a first power supplying open hole (15) for the electrical connection of a start-up device (30), and a second power supplying open hole (16) for the electrical connection of a motor protector (40). The base body (10) is provided with a first chamber (17) for holding the start-up device (30), and the chamber is closed opposite to the shell cover (20) of the convex ram (12). A second chamber (18) is fixed at the lateral side of the first chamber (17). The motor protector (40 and 40') is arranged inside the second chamber (18).

Description

[0001] This application is a divisional application of the patent application whose application number is 01821780.X, the application date is November 30, 2001, and the invention title is "Electric Motor Starting System Building Device". technical field [0002] The invention relates to a construction device for starting systems of the type used in electric motors, in particular single-phase induction motors in hermetic compressors of the refrigeration type. Background technique [0003] Single-phase induction motors are widely used due to their simplicity, efficiency and high performance. They are commonly used in household appliances such as refrigerators, freezers, air conditioners, hermetic compressors, washing machines, water pumps, fans, etc. They are also used in some industrial applications. [0004] Existing induction motors usually have a cage-type rotor and a helical-type stator. There are also two windings in the motor, one for the running coil and the other for ...
