The electric motor is divided according to the type of electrical power supply motor, it can be divided 2 type is a DC motor and AC motor. Currently, said that 90.To do this, engineering projects, the three phase induction motor the probe with the purpose to study the efficiency of the motor after use. 500 hours. By paving the hope will be useful to the public.Legend, heavy and size 1 horsepower sperm as one body connected to test equipment, the equipment ใช้ทดสอบ. Electric power meter power meter The base consisted of motor with the experimental set.Legend set enter burden. The horsepower of 2.1 Nm. And test machine motor 1 horsepower. The burden of 6.5 entered Nm.In which each test to test working time 10 hours a day 1 times. And will be tested until 500 hours, which will keep the 10 every hour. The result is derived to calculate the efficiency...
