What are the selection principles for three-phase asynchronous motors? This post was last edited by lihy on 2009-2-11 09:32.]
Take a look at these two: http://bbs.hcbbs.com/thread-311959-1-1.html http://bbs.hcbbs.com/thread-339624-1-2.html
The selection of a motor should be based on the nature of the load, as well as the requirements regarding the motor’s starting, reversing, and speed control； Requirements such as load torque, speed range, and frequency of starting and stopping ； Consider the temperature rise limits of the motor, its overload capacity, as well as the limits on starting torque and starting current ； As well as various factors such as working environment conditions, it is necessary to properly select the motor’s power, operating mode, and protection structure type. If the construction machinery design institute (office) is responsible for the design and manufacturing, the manufacturer shall order the motors from the motor manufacturers designated by the design institute (office), in accordance with the motor model, specifications, and requirements chosen by the institute (office).
For motors, what power level generally requires the addition of current monitoring?
Here, we usually add it for units of 30-55KW and above. .
The environment, load, working hours, and work capacity, I guess.
