Preventive maintenance of motors and controls Electrical
A wellplanned preventive maintenance program is the key to dependable, longlife operation of motors and generators modern plant operations, unscheduled stoppage of production or long repair shutdowns are intolerable. The high cost of the resultant downtime eats deeply into profits. Although management probably realizes the value of a good preventive maintenance (PM)

Elevator Machine and Drive System ~ Electrical Knowhow
The mating surfaces of these two elements are contained within an oil bath for lubriion. Regular access to the machine to check the level of oil, as well as the condition of the oil and the ring gear is an important aspect of ongoing equipment maintenance. 7 Machine Bedplate . The gear box, motor and brake may be assembled on a common bedplate.
To plan maintenance effectively, it is essential to have accurate condition information about when components need repairing or replacing. A variety of offline and online diagnostic methods conducted during commissioning and acceptance testing as well as inservice maintenance on rotating machines allow a reliable insulation condition assessment.
