Description

Rescue device for starting system of electric motor {CONSTRUCTIVE ARRANGEMENT FOR THE STARTING SYSTEM OF AN ELECTRIC MOTOR}

The present invention relates to a rescue device for a starting system of the type used in electric motors, in particular single phase induction motors used in refrigeration hermetic compressors.

Single phase induction motors are widely used because of their simplicity, strength and high performance, and these single phase induction motors are generally found in household applications such as refrigerators, freezers, air conditioners, hermetic compressors, washing machines, pumps and fans as well as some industrial applications. Can be.

Known induction motors typically have a caged rotor and a coiled stator and have two windings: a winding for the driving coil and a winding for the starting coil. During normal operation of the compressor, the operating coil is supplied with alternating voltage and the starting coil is temporarily powered at the start of the starting operation, creating a rotating magnetic field in the air gap of the stator, which accelerates the rotor and starts the motor. To form the state necessary to facilitate

This rotating magnetic field may be obtained by supplying the starter coil with a time shifted current, preferably at an angle close to 90 ° with respect to the current flowing in the main coil. The time-displacement between the currents flowing in both coils is achieved by the structural feature of the coils or by installing an external impedance in series with one of the coils, usually the starting coil. The value of this current flowing in the starting coil during the start-up of the motor is generally high, so it is necessary to use a switch of the type to cut off this current after the time necessary to accelerate the acceleration of the motor.

In an electric motor requiring very high efficiency, this starting coil is not completely disconnected after the starting period has elapsed, and a capacitor, i.e., a running capacitor, is kept in series with the starting coil, so that the maximum torque of the motor is maintained. And provide sufficient current to increase efficiency.

In motors having such a configuration using permanent impedance in series with the starting coil during normal operation of the motor, several starting devices of PTC or electronic type are known, as disclosed in US Pat. No. 5,051,681.

Another structural component of the known starting and protection module for an electric motor is a thermal protector, which has the function of protecting the motor under short circuit or overload conditions. This component may be mounted directly to or received by an energizing pin of the compressor, connected to the compressor by an electrical conductor, or installed inside the compressor, for example in contact with a winding of an electric motor. It may be.

In some known constructions for the starting system, the starting system comprises a module which houses the starting device and the motor protector inside and carries at least one capacitor, ie an operating capacitor, outside. The capacitor is attached to this module via a capacitor support (US Pat. No. 5,170,307) or directly to the module (US Pat. No. 5,729,416).

In other known constructions, the starting system eliminates the use of capacitors or makes it possible for the operating capacitor (including the starting capacitor, if a starting capacitor is provided) to be operatively coupled to the module of the starting system by means of suitable connection cables. (WO98 / 21735).

In a structure in which the operating capacitor is attached directly or through a support to the module of the starting system, a fixed or detachable rod having a pin at its free end is provided to receive the engaging portion of the operating capacitor. In the solution proposed in US Pat. No. 5,729,416, a lateral groove is provided at the end of the stationary rod of the operating capacitor, preventing the capacitor attached to the module of the starting system from moving. Nevertheless, these grooves do not prevent the driving capacitor from inadvertently displaced from its mating position with respect to the module, since these grooves do not provide axial retention to the driving capacitor.

While known solutions for the modules of the starting system simplify the assembly of the starting and protective elements of the motor of the compressor, these known systems, due to their versatility, require different configurations of the starting system of the motor and require a starting system with suitable specifications. The disadvantage is that there is not enough flexibility to make it suitable for the application. In the solution proposed in US Pat. No. 5,729,416, the rescue device comprises a shell formed by a starting body and a base body accommodating a thermal protector, the cell being completely and securely closed during manufacture and starting up Depending on the application given to the system, a specific structure is required. Thus, the rescue device of US Pat. No. 5,729,416, after leaving the assembly line, does not allow for the relocation of the components, because the cell is completely closed, so that the starting device and the heat protector used in manufacturing are internally Because it is sealed. Due to these structural features, motor buyers must stock different types of modules for different applications. For example, if a problem occurs in the thermal protector, the entire module must be replaced and the starting device can be worn out. The same is true when a fault occurs in the starting device. Moreover, since the cover is designed to close the entire main body of the cell, neither the starting device nor the thermal protector can be replaced.

Another feature of the known rescue device is that the cell has a specific design for incorporating a double tubular extension comprising an opening for the power terminal when an insulation protection device is needed to prevent the user from accessing the power terminal of the module. It consists of. To this end, it is necessary to double the number of tools for manufacturing different types of cells, which increases manufacturing costs while reducing productivity and also increases the number of stock items.

It is therefore an object of the present invention to have a strong yet simple structure, to be easy to assemble, and to arrange the placement of components after the manufacture of the modules forming the starting system, without causing component loss or using different cell designs. It is to provide a rescue device for a starting system of an electric motor having sufficient flexibility not only to retrofit but also to retrofit electrical insulation protection means of a power supply terminal.

Another object of the present invention is to prevent other capacitors of the same type from being connected to the module when the capacitors are directly attached and mounted to the modules of the starting system, and also to prevent access to the live and unused terminals of these modules. It is to provide a rescue device for the starting system of the electric motor as described above.

The rescue device for the starting system of an electric motor according to the present invention is of a type including a basic body on which a cover is mounted, a starting device and an electric motor protector. The base body has a protruding rod for attaching a capacitor to an outer surface thereof; A pair of first openings in which respective terminals of the capacitors coupled to the protruding rods are fitted, and arranged in alignment with the pair of first electrical connectors provided inside the basic body; A first conducting opening for electrical connection to the starting device; And a second conduction opening for electrical connection to the motor protector. This basic body forms a first housing for receiving the starting device, which is closed by a cover on the opposite side of the protruding rod, the cover for receiving two pins for electrical connection to the motor. It has two receiving openings aligned with a pair of female connectors installed in the body. The motor protector has a female connector for introduction of a third pin for electrical connection to the motor, and is mounted in a second housing provided on the side of the first housing. The motor protector also has a contact pin aligned with the second conducting opening.

In the structure proposed by the present invention, the cover is provided only in the first housing, allowing access to the motor protector provided in the second housing even after the manufacture of the module. The proposed device thus makes it possible to use only one starting module which can accommodate a motor protector suitable for the particular application given to the starting system. The application of the motor protector may be made in the production line of the device using the starting system during manufacture or during maintenance of the device, such as a hermetic compressor, at the end user's site.

Another aspect contemplated is the reuse of one of the two components, depending on which defect is present.
