Electric motor 250 kW - 750 RPM - 400/690V - IE3 - Cast Iron

Ref: GMM3E 355 L 8d

The Gamak 250 kW three-phase electric motoris a high-power industrial drive solutionfor equipment requiring high drive capacity, significant torque, and maximum reliability in intensive use. Thanks to its 8-pole (50 Hz)design, it offers a rotational speed of 750 rpm, perfectly suited for applications requiring progressive, smooth, and controlled power transmission.

Equipped with a smooth shaft with a 100 × 210 mm keywayand an axis height of 355 mm, this motor is easily integrated into many industrial installations such as large-capacity pumps, industrial fans, heavy-duty conveyors, mechanical reducers, production lines, or professional agricultural equipment.

Its high-strength cast iron casinggives it excellent mechanical robustness and high resistance to vibrations, repeated stresses, and harsh operating conditions. This design ensures good heat dissipation and optimal motor stability, while its IP55 protection ratingguarantees effective protection against dust and water splashes in demanding industrial environments.

Thanks to its IE3 energy efficiency, this motor helps limit electricity consumption while maintaining a high level of performance. Its Class F windingensures excellent thermal resistance and helps extend its lifespan, even during prolonged operation under heavy load.

The Gamak 250 kW three-phase motoroperates on a 400/690 V three-phase supplyand is available with B3, B5, and B35mountings, allowing for flexible adaptation according to mounting needs. Its design with standardized dimensions also facilitates the replacement of an existing motor with equivalent characteristics.

With its exceptional power, robust construction, and performance suitable for heavy industrial applications, this motor is a reliable and durable solution for industrialists, machine builders, and maintenance servicesseeking a high-performance drive for their most demanding installations.

  • Power

Discover the 250 kW electric motor with a smooth and keyed shaft with a diameter of 100x210mm. It rotates at a speed of 750 rpm, or 8 poles, at 50Hz. This type of 250 kW electric motor can replace a standard motor of an equivalent brand, without modification. It is designed with a cast iron frame and has an IP55 protection rating. This 250 kW three-phase motor must be powered by a three-phase voltage of 400V or a three-phase voltage of 690V. Its high IE3 efficiency will lead to energy savings.
