Motor common fault analysis and maintenance - the choice of the motor

1.According to the motor installed.Point of the surrounding environment to choose motor forms: rural common forms a protective type of motor and enclosed two kinds.Protection type ventilation performance is good,price is low,suitable for dry environment,place electrical motor USES less dust;If dirt is more,water splash,enclosed motor should be adopted.Such as agricultural and sideline products processing machinery and water pumps can be used in this kind of motor,in addition,there is a motor run capacitor sealed motor,bail can be immersed in the water work,this kind of motor electric submersible pump is adopted.2.According to use load condition,select the motor power: the power of the motor general should be in the production of electricalmotor1.blogspot.com mechanical power 1.1~1.5 times.If too much power to choose,not only to increase investment,but also reduces the mechanical efficiency,increase the cost of production.If power choice is too small,motor to bear too much load for a long time,can make temperature rise is too high and damage the insulation,shorten the motor to asynchronous motor make in life.3.According to the requirements of the machine speed motor and transmission way,speed and production machinery matching principle is to make the motor is running under the rated speed,the same way transmission.
