T-T Electric proposes a series of square frame ac motors for variable speed applications with flux vector control types. This asynchronous motor has been developped and designed to achieve the same high performance and dimensions as dc motors of similar power. The AC Square motor complies with IEC 60034 standards and responds to the requirements for most industrial applications. The compact and flexible square frame design facilitates its integration into all types of machinery. |

The mechanical and technical characteristics of AMP motors can be compared to DC motors. Speed ranges: • from 0 to nN : Constant Torque • from nN to n1: Constant Power • from n1 to nmax: Power decreasing as 1/n (Field weakening range) As standard,the motor is wound for nominal voltage 400V for base speed nN In IP23: n1 = 1.6 nN In IP54/55: n1 = 2.1 nN |
• Compact square frame • High operation speed range (Up to 8000rpm) • High overload capability • Fast response with low rotor inertia • Low maintenance requirements |
