ZC2516S series intelligent low resistance tester is specially used to test various resistances. The 24 bit color 4.3 inch color LCD screen with touch function is simple in operation and fast in testing. It is suitable for various resistance design, inspection, quality control and production testing. This machine has three gear sorting function. In the sorting state, the resistance value or percentage value can be selected to display, and the resistance value can be judged as too large, too small or good according to the set value. At the same time, there is a sorting interface on the back panel of the instrument to enable the interface to start the signal and enable the instrument to measure. The test results are output from the interface on the back panel at the same time. Through this signal interface, the instrument can be connected to the component mechanical processing equipment for automatic testing. In addition, the machine has a USB interface and a Handler interface. The panel function can be completely controlled by the computer. The test results can also be sent back to the computer for saving through the USB interface or USB interface, or the data can be directly saved in a USB flash disk.

Brief introduction

The ZC5840 micro motor tester is a test equipment for the life aging of motors, etc. The internal core chip is professionally used for off-axis moment of inertia (ERM) and linear resonant actuator (LRA) (with built-in library and intelligent control Eng) Haptic drive. This series of devices uses a special LRA control algorithm called automatic resonance tracking. Automatic resonance tracking uses the back-EMF of the LRA to monitor and track the resonance frequency. Later, it can use this resonant frequency information to drive the closed-loop LRA. Automatic resonance has many benefits and makes LRA fusion simple: the rotor vibration is stronger and more consistent, the power consumption of the resonance drive is lower, it has the ability of over-speed driving and LRA braking to obtain better response time, which is the current test The most suitable method for the motor. Compared with the previous method of measuring F0 with a sine wave, and then using the corresponding F0 value to de-age the motor, the method has improved a lot.
