If you complete your tests and find one or more problems with your motor, there are a few things that you can do depending on the problem at hand.
The stator core is usually constructed of iron to reduce load losses. High efficiency - induction motors have high efficiencies. To measure the input power two-wattmeter method is used. This growler acts as an open-ended transformer that induces AC power into the rotor's armature for the purpose of checking for the presence of shorted turns. The steel laminations, squirrel cage, and bearings, are all mounted onto the rotor shaft. Disconnecting the motor from power: When you are ready, move the transformer's motor disconnect switch to take it off of power. When the motor stator winding is damaged by moisture or external impact, the insulation value of winding and stator core and rotor insulation material is greatly reduced or even zero, the motor case with a point cannot start normally, the machine temperature is greatly increased or even burned out. B. The Influence of Select Losses Components on Induction Squirrel-Cage Motor Efficiency. strength of the magnetic lines of flux. The complete weight of the motor is transferred to the structure or ground through the feet. What is a Wound Rotor Motor and How Does it Work? When a motor fails to start, runs hot, continually trips or sputters, there are many possible causes.
The detection method is to use a multimeter resistance or bridge to detect the DC organization of each phase winding, if it is lower than the specified value, open the end cover to check the winding to find out the fault point, if the damage is not serious available insulation material to repair; if the serious short circuit, has burned the coil, according to the actual situation re-embedding wire processing. The fan forces air across the exterior of the motor frame to cool it during operation. The terminal housing shields the connection board and electrical connections from foreign object damage such as water. How to test a squirrel cage motor design b. You should also be sure to wear rubber gloves during the test to protect yourself from electric shock.
