When does the low voltage motor need to be repaired?
Until now, the detection and preventive maintenance of low-voltage motors has been a time-consuming and costly process. ABB's new technology transforms simple motors into smart devices that tell when maintenance is needed. The smart sensor is directly connected to the motor and provides data during the operation of the wireless connection.
In addition to cutting maintenance and repair costs, the new technology will also make it easier for motor users to implement ABB's “Internet of Things, Services and People” (IOTSP) philosophy. The idea is that ABB is proposing to use digital opportunities for its customers, including small and medium-sized businesses.
Smart sensors measure motor vibration, temperature or periodic overload and calculate power consumption. The data is analyzed by specially developed software and presented to the plant operator as an image. The operator maintains the work according to the data plan, which reduces downtime by 70%. At the same time, the motor's service life can be extended by 30% and save 10% of energy consumption.
The user can check the status of the motor at any time and will give an alarm when a problem is detected. ABB said the cost of investing in the new condition monitoring technology could be recovered within a year.
“This innovative solution makes condition monitoring a new standard for low-voltage motors,” said Pekka Tiitinen, president of ABB's Discrete Automation and Motion Division. “Optimized maintenance programs help to significantly reduce maintenance costs. Significantly reduce or even eliminate unplanned downtime Time. The increase in usability has greatly improved the productivity of our customers."
The monitoring sensor can be installed in the motor production plant or it can be modified in a few minutes on an existing low-voltage motor (motor of any age from any manufacturer).
There is no electrical connection between the sensor and the motor, so unauthorized parties cannot access the motor through this path. Smart sensors wirelessly transmit data to a cloud-based server using an encryption protocol through a smartphone or gateway. Data stored in the cloud is also encrypted, using special algorithms to analyze the data on the server. The Internet-based customer portal uses a role-based protocol to allow users to securely access data.
