DATA AND DRAWINGS IP54 IP55 38, General information. T T Electric proposes a series of square frame ac motors for variable speed drives applications. This asynchronous motor has been developed and designed to achieve the same dynamic performance as. for DC motors series, The AC square motor complies with IEC600 34 standards and responds to the requirements for most. industrial applications Its flexible square frame design facilitates its integration into all types of machinery. AMP are 3 phase asynchronous squirrel cage 4 pole motors manufactured in degree of protection IP23 and. IP54 55 9 sizes 112 132 160 180 225 250 280 315 355 are proposed covering a power range from 16 to. 1300 kW at 1500 rpm, TYPE OF DESIGNATION OPERATING CURVES. The mechanical and technical characteristics of, Frame Core. Size Length, AMP motors can be compared to DC motors.
