Problems solved by technology

[0003] At present, motors using centrifugal switches are not yet popular in China, so the durability test methods for mechanical centrifugal switches are not unified. Most of them use time relays, control relays and generators as loads. The overall system is cumbersome and Poor operability, even expensive, and relatively complicated to implement

Embodiment Construction

[0026] The present invention will be further described below in conjunction with accompanying drawing:

[0027] Such as Figure 1-Figure 5 A kind of motor centrifugal switch endurance testing device shown, comprises the motor 1 that is provided with centrifugal switch 2 that is connected with power supply 8, also includes the controller 5 that is connected with motor 1 input end and is used for controlling motor 1 start-stop, and The analog load 3 connected to the output end of the motor 1 and the counter 6 connected in parallel with the controller 5 . After the power supply 8 is turned on, the start-stop time ratio of the motor 1 is set by the controller 5, the controller 5 controls the motor 1 to start, and the centrifugal switch 2 arranged on the motor 1 is energized and is in an off state; at the same time, the counter 5 passes its The voltage generated above is counted once; when the motor 1 stops, the controller 5 controls the motor 1 to stop, the centrifugal switch 2 i...

Abstract

The invention relates to a motor centrifugal switch durability test device comprising a motor which is connected with a power supply and provided with a centrifugal switch. The device also comprises a controller which is connected with the input end of the motor and used for controlling on / off of the motor, a simulated load which is connected with the output end of the motor and a counter which is connected in parallel with the controller. The motor centrifugal switch durability test device is simple in structure, convenient to operate and economical in cost. The invention also relates to a motor centrifugal switch durability test method. The test method is safe and reliable and high in practicality and provides the quality guarantee for development of the matched motor and terminal product. The counter is connected in parallel with the controller and used for performing statistics of the number of cycles of durability testing so that on / off time can be arbitrarily adjusted, over hundreds of thousands of times of mechanical durability testing can be realized and thus the product is enabled to meet the design requirements.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a durability test device and a test method for a centrifugal switch of a motor. Background technique [0002] Centrifugal switch is one of the core components for small single-phase asynchronous motors, both in terms of function and safety. The durability of the mechanical centrifugal switch directly determines the life of the motor and even the whole machine. Therefore, the durability test of the mechanical centrifugal switch is particularly important. [0003] At present, motors using centrifugal switches are not yet popular in China, so the durability test methods for mechanical centrifugal switches are not unified. Most of them use time relays, control relays and generators as loads. The overall system is cumbersome and The operability is poor, and even the cost is relatively large, and the implementation is relatively complicated. Contents of the invention [0004] Th...
