Description
The TEC T2A IE2 0.25 kW 6 pole three-phase motor is an aluminium IE2 high efficiency induction motor in IEC frame size 71 (frame reference 712-6), foot mounted (B3). It gives 0.25 kW at 910 rpm on a 415v three-phase supply and has a 14 mm diameter, 30 mm long output shaft.
B3 means foot mounted: the motor bolts down through the four feet on its base with the shaft horizontal. It suits pumps, fans, compressors and gearboxes on a baseplate, driven through a coupling, pulley or belts. The same motor is also available B35 foot and flange mounted and B34 foot and face mounted.
As a 6 pole motor it has a synchronous speed of 1,000 rpm and runs at 910 rpm at full load. For a different speed at the same power, see the 0.25 kW 2 pole (2,840 rpm) and 0.25 kW 4 pole (1,385 rpm) versions. The IEC frame size sets the fixing dimensions, so the shaft centre height on the feet is 71 mm and this motor fits the same mounting as any other IEC 71 frame motor with the same mounting type.
The TEC T2A range has a lightweight aluminium body, built to current European mechanical and electrical standards for wet and dusty conditions. It is wound for dual voltage, rated for 50 and 60 Hz, and has inverter-rated insulation, so it can run from a variable speed drive. The temperature rise is Class B (110°C), it is rated for continuous duty (S1), and it has a sheet metal fan cover, an aluminium terminal box with metric cable gland entries and a gasket, and a PTC thermistor in each phase for overheat protection.
