Motor winding parameter converter

Abstract

A motor winding parameter converter is composed of a first contactor, a terminal base, a second contactor, a side cover and auxiliary components, wherein the first contactor, the terminal base and the second contactor are assembled into a whole in a wedging mode through a mortise joint structure arrange on a shell body and are fastened through fastening screws and nuts, terminals and static contacts inside the first contactor, the terminal base and the second contactor are correspondingly connected through three-hole connecting pieces and / or two-hole connecting pieces to form an integral electric system, electromagnetic coils of the first contactor and the second contactor are independent of each other, different on-off relation combinations are formed between the static contacts and the terminals by controlling the working states of the first contactor and the second contactor, and then a motor winding is controlled. The motor winding parameter converter is suitable for various types of motors, convenient to install and maintain, small in size, capable of being directly installed in a motor junction box to replace a wiring terminal, simple in structure, low in energy consumption and convenient to popularize.

Problems solved by technology

[0002] With the advancement of science and technology, all kinds of machinery and equipment are more and more widely used in every field of people's life day and night. Among all the components of equipment, the motor is one of the most widely used and most used components. Although new New materials for products are constantly being developed, but the principles and structures of all motors currently in service are basically fixed in several typical types, and most of the realization of motor winding parameter transformation is also fixed in several typical methods, which is very important for motor control products. The development and promotion of the motor provide great convenience, but at present, the method of realizing the transformation of the motor winding parameters generally adopts the method of combining multiple non-energy-saving traditional parts into an overall control circuit, which not only has many connecting wires, complex assembly, and high assembly cost. , not energy-saving, and bulky at the same time, it is not suitable for installation on the motor casing. In this way, many wires must be led to the control circuit in the multi-winding motor, which wastes materials and easily causes interference and failure

It can be seen that in the face of the huge number of motors in operation, the above-mentioned shortcomings and deficiencies in the control of motor windings need to be overcome and improved urgently.
