Embodiment 1
[0022] Such as figure 1 As shown, in the elevator traction motor vibration online detection system of the present invention, the power supply 8 provides electric energy for all electrical components of the detection system, and the power supply is a constant voltage power supply; the signal processing module collects and amplifies the data collected by the sensor , the signal processing module includes a signal amplifier 6 and a data collector, the signal amplifier 6 amplifies the signal of the sensor, and the data collector is used to collect the signal conveyed by the signal amplifier 6 .
[0023] Such as image 3 and Figure 4 As shown, the sensor is used to collect the vibration signal of the traction motor, which includes a casing 1, a telescopic support 2, a base 3, a flexible sleeve 4 and a capacitor 5, and the capacitor includes a fixed plate 55 and a movable plate 54, so The telescopic bracket 2 is connected to the shell 1 and the base 3, and the base 3 is fixed on ...
Embodiment 2
[0030] The difference from Embodiment 1 is that the vibration sensors include multiple groups, installed on different working end faces of the traction motor, to detect the vibration of the motor in a more comprehensive manner.
