In order to ensure that the mechanical equipment is always in good technical condition and can be put into operation at any time, reduce the failure downtime, improve the mechanical integrity and utilization rate, reduce mechanical wear, prolong the service life of the machinery, and reduce the mechanical operation and maintenance costs, energy-saving intelligent motors and fans are being more and more used in mechanical equipments and systems.
There are many kinds of mechanical equipment. When the mechanical equipment is running, some of its components and even itself can carry out different forms of mechanical movement. Mechanical equipment consists of driving device, speed change device, transmission device, working device, braking device, protective device, lubrication system, cooling system, etc.
