Selection of IEC standard motor power from 0.18 kw to 375 kw, NEMA standard motor power range 1 HP - 300 HP.Can provide CE and UL certification, NEMA motor service factor of 1.15, protection grade IP23, IP44, IP55, protection form the ODP TEFC.According to the requirements of variable torque load, motor can choose frequency conversion device.

IEC standard motor     

IEC standard, mainly used in European countries such as Sweden, Germany, France, Britain and other countries.China's GB standard is similar motor with IEC standard.IEC standard motor operating frequency is 50 hz, working voltage is 380 v, and the corresponding motor synchronous speed is 3000 RPM the 2 pole motor;4 pole motor 1500 RPM;6 pole motor 1000 RPM.Famous brands are: the motor motor, SIEMENS, ABB, LS (LEROY SOMER) LEROY SOMER Emerson motor, etc.
Currently many countries in the world (including China) of the motor system energy saving are given attaches great importance to, the United States, Europe, Canada, Australia and other countries and regions have developed about the standards of energy efficiency of the motor.In 1992, the U.S. department of energy (doe) released a new energy laws and regulations, rules on the efficiency of three phase asynchronous motor efficiency standards, and from October 24, 1997 formally began.Canada also formulate the corresponding energy efficiency ordinance in 1992, and formally went into effect since 1999.European electrical and electronic manufacturers association (CEMEP) decided in 1999 to 1999 to 50% reduction in lower level motor production efficiency.And after 2006, no longer to produce low efficiency level motor.CEMEP and according to the grade of the eu directives on the motor efficiency level, efficiency can be divided into EFF1, EFF2, EFF3 at three levels.There is European companies such as SIEMENS, ABB has developed for eff1 grades of high efficiency motor efficiency, and has set up a market.
