At speed higher than "N1max" the power is reduced.
• High operation speed range
(Up to 8000rpm)
• High overload capability:
→ 120% continuously
→ 130-140% for 30 minutes
• Fast response with low rotor inertia
• Low maintenance requirements

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 motors can be controlled up to the specified nominal speed "Nom. Speed" at constant torque and up to speed "N1max" at constant power. At speed higher than "N1max" the power is reduced. • High operation speed range (Up to 8000rpm) • High overload capability: → 120% continuously → 130-140% for 30 minutes • Fast response with low rotor inertia • Low maintenance requirements |
