TEFC IC411

Product Introction

This series of tefc IC411 motor is suitable for continuous working duty (S1), having the characteristics of low loss, high efficiency, compact structure, stable operation, low vibration, low noise, long service life, convenient use and maintenance, etc. They can be widely mounted in machine tools, water pumps, fans, compressors, reducers, and also suitable for many mechanical transmission equipment, such as transportation, mixing, printing, agricultural machinery, food, etc.

The stator frame is the outer part of the motor. The function of the stator frame is to provide support to the stator core and stator winding.

It provides mechanical strength to the inner parts of the motor. The frame has fins on the outer surface for heat dissipation and cooling of the motor.The frame is casted for small machines and it is fabricated for a large machine. According to the applications, the frame is made up of die-cast or fabricated steel, aluminum/ aluminum alloys, or stainless steel.

The function of the stator core is to carry the alternating magnetic flux which produces hysteresis and eddy current loss. To minimize these losses, the core is laminated by high-grade steel stampings thickness of 0.3 to 0.6 mm. These stampings are insulated from each other by varnish. All stampings stamp together in the shape of the stator core and fixed it with the stator frame. An inner layer of the stator core has a number of slots.

The stator winding is placed inside the stator slots available inside the stator core. Three-phase winding is placed as a stator winding. And three-phase supply is given to the stator winding. The number of poles of a motor depends on the internal connection of the stator winding and it will decide the speed of the motor. If the number of poles is greater, the speed will less and if the number of poles is lesser than the speed will high. The poles are always in pairs. Therefore, the total number of poles always an even number.
