A washing machine motor test device based on actual load

Abstract

The invention provides a washing machine motor testing device based on an actual load. The testing device utilizes the actual load of a washing machine to replace a traditional artificial load to test the operating state of a motor, can effectively acquire required design input information of the used motor with different loads before design and development to enable a design objective more definite, and avoids the blind and repetitive design. The washing machine motor testing device can realize assembly and disassembly for different washing machine platforms, different transmission mechanisms and different motors, achieve the optimal matching design among the all three through a combinatorial test, shorten the development cycle of the motor, control the material cost accurately and improve the core competence of a product.

Description

technical field [0001] The invention relates to the technical field of washing machine motor performance testing, in particular to a washing machine motor testing device based on actual load. Background technique [0002] At present, the design target values ​​collected before the design and development of the motors used in the domestic washing machine industry are all theoretical empirical values. After the products are developed, the parameters of the motors at the characteristic points are tested by using a dynamometer to load simulated loads. However, the specific parameters such as the actual output power and torque required for the motor to be assembled on the washing machine cannot be known. In the case of a certain transmission mechanism, it is impossible to determine whether the motor is completely matched with the actual load, and sometimes there will be insufficient performance or excess margin, which is not good for the development cycle and cost control of the ...
