Problems solved by technology

The current way to drive compressors is to drive different compressors by matching different eeprom parameters on the basis of a fixed underlying driver program. As a result, if the driver boards required for production and after-sales maintenance are matched according to the compressor model, tens of It is very difficult to produce and manage each type of driver board, and some original driver boards have been discontinued for a long time.

Embodiment Construction

[0014] The present invention aims to propose a generalized motor drive matching method, which can automatically match the compressor according to the identified motor parameters, thereby obtaining the corresponding drive parameters and realizing the generalization of matching with various types of compressors. Its core idea is: by writing all the parameters in the eeprom of various types of compressors that are compatible with the product into the driver program, since the eeprom includes not only the motor drive parameters of this type of compressor, but also the corresponding parameter information of the motor (such as resistance , d-axis inductance, q-axis inductance, counter electromotive force constant and other information), so when driving the motor, the specific model of the motor can be identified based on the identification of the relevant parameters of the motor, so as to call the corresponding driving parameters for driving, to achieve and each Generalization of mod...

Abstract

The invention relates to the field of motor drive, and discloses a generalized motor drive matching method, which automatically matches compressors according to identified motor parameters, thereby obtaining corresponding drive parameters and realizing generalization of matching with various types of compressors. The method includes the following steps: a. matching the eeprom parameters of various types of compressors adapted to it according to product requirements; b. writing all the parameters in the eeprom of each compressor that have been matched into the driver program; c. when driving the motor , first identify the relevant parameters of the motor, and then judge the model of the motor according to the identified motor parameters, so as to call the driving parameters of the motor of this type in the driver program to drive the motor. The invention is suitable for generalized matching of motor drives of household appliances.

Description

technical field [0001] The invention relates to the field of motor drive, in particular to a generalized motor drive matching method. Background technique [0002] For household appliances with motors such as refrigerators and air conditioners, the core of the control system is the compressor. At present, manufacturers are using more and more compressor models due to reasons such as cost and performance improvement. However, the current way to drive compressors is to drive different compressors by matching different eeprom parameters on the basis of a fixed underlying driver program. As a result, if the driver board required for production and after-sales maintenance is matched with the compressor model, dozens of It is difficult to produce and manage each type of driver board, and some original driver boards have been discontinued for a long time. Therefore, how to realize the generalization of motor drive is a hot issue studied by various businesses. Contents of the in...
