Categories Medium Voltage Electric Motors
Medium voltage motors are motor solutions designed for transporting heavy loads and executing complex applications in industrial processes requiring high power. Used in a wide range of applications from oil and gas plants to cement production, mining and power plants, these motors play a critical role in processes that require high strength and reliability. GAMAK medium-voltage asynchronous motors offer performance that exceeds industry standards thanks to their long-lasting frame construction, high efficiency class options and engineering designs adaptable to harsh conditions. The brand produces solutions that are compatible with different industrial requirements thanks to their tailored design, customized production and wide application flexibility.
Technical Specifications of Medium Voltage Motors
GAMAK medium voltage motors are designed according to advanced engineering criteria to ensure efficient and safe operation under heavy-duty conditions. These motors offer high durability with a rotor, cast iron frame, IP55-56 protection class, Class F insulation (155 °C) and Class B temperature rise (80K). The TEFC, TEFV and TEAAC constructions with totally enclosed cooling solutions ensure that the motor maintains a stable temperature profile during long-term operation. PT100 temperature sensors placed at the bearing and winding points increase the operational safety of the motor. This technical structure sets GAMAK apart in the global market in terms of medium voltage motor specifications.
These motors are designed to provide high dielectric strength in the 3,000-10,000 V voltage range and can operate safely thanks to their reinforced insulation structure. The wide range of mounting options offers installation flexibility to suit field conditions, while the improved air ducts and housing geometry improve the thermal efficiency of the motor, ensuring stable performance over long periods of operation.
Power Ranges of Gamak Medium Voltage Motors
The motors in the series cover a wide power range from 150 to 4000 kW. Depending on the application requirements, 4-pole or 6-pole models can be preferred. Operating in the 3.000 V - 10.000 V voltage range, these motors are suitable for direct supply from the grid and can be used with DOL, VFD (with reinforced insulation) and Soft Starter. These options allow the motor to offer optimum starting current and speed control according to process conditions.
Efficiency and Protection Classes of Gamak Medium Voltage Motors
Medium voltage motors are safely protected from outdoor factors, dust and liquid splashes thanks to IP55-56 protection class. Insulation class F offers resistance up to 155 °C, while maintaining the temperature rise in class B increases the thermal efficiency of the motor. First-class cooling systems help the motor maintain a stable operating temperature according to different workload profiles. This structure makes high performance sustainable in harsh industrial environments.
Frame Size of Gamak Medium Voltage Motors
GAMAK medium-voltage motors have a cast iron frame, which provides high mechanical strength and helps to keep vibration levels under control. The 180-degree rotatability of the terminal box and different mounting options (IMB3, IMV1, IMV3) facilitate the integration of the motor in the field. While protection is provided with standard RAL 7031 paint, different paint options can be applied upon request.
Where are Medium Voltage Motors Used?
Medium voltage motors are used in all industrial processes that require high power and durability. Oil and natural gas production facilities, marine systems, pump and compressor groups, cement and mining equipment, paper production lines, metal processing machines and water treatment plants are among the most common areas where these motors are utilized. Stable performance in applications requiring complex torque and a wide power range make GAMAK medium voltage motors one of the preferred solutions in the heavy-duty category.
