DMI-DC motors
What is the DMI motor?
The DMI motor series is ABB’s latest DC product range in the market. It combines improve output performance with less maintenance, higher reliability and adaptability compared to conventional DC motors. This means increased productivity and a smooth integration in almost any application.
The DMI benefits from all the know-how and experience embodied in its highly successful predecessors, and represents the next step in the evolution of DC motors.
What are the main features?
- Frame size IEC 180, 200, 225, 250, 280, 315, 400
- Comp. wind frame size 250
- Power up to 1400 kW / 1910 HP
- Torque up to 22 kNm
- Voltage up to 810 V
- Field voltage 110-440 V
- IM Horizontal or vertical, foot or flange
- IP 23-55
- IC 06, 17, 37, 86W, 666, 410
- Insulation Class 200
- Standards IEC, CE, CSA (up to 710 V)
The DMI DC motor is designed to allow fan cooling, air/water and air/air heat exchangers, external cooling or frame cooling. The wide selection of options and built-in flexibility means that these motors can be tailored for any application and industry
DMI motors comply with the requirements of class 200 insulation.
The insulation system is moisture resistant and has a temperature index well above class H.
The built-in extra margin is substantial, which ensures a very long life.
During the development of the DMI’s patented cross-section, efforts were taken to increase the power output, toque and speed range uniquely combined with lowered electrical stress. The key behind DMI’s peak performance lies in optimization of the electromagnetic circuit, reduced flux intrusion from the cooling ducts and improved efficiency of the cooling
The DMI has positive environmental characteristics. In Fact it was the first rotating machine in the world which was granted the Environmental Product Declaration certificate, issued by BVQI.
Due to the smart mechanical design the DMI can be designed for tandem or even triple installations ABB has an unsurpassed experience in delivering tandem solutions to different customer in the metals industry.
The rotor’s skewed coil slots give the motor excellent low-speed characteristics and also a lower noise level.
What are the customer values?
High output and small dimensions
- Increased productivity and capacity
High output over a wide speed range
- More flexible solution and wider commutation margins
Smooth running at low speeds and low moment of inertia
- Shorter cycle times and smaller converters
Simplicity of DC and the minimum of maintenance
What is ABB’s total DC offering?
ABB’s DC motors and drives are rated from 10 kW up to 2,0 MW and are among the industry’s best performers in terms of power output, torque and speed. All products conform to ISO standards. ABB’s intensive R&D programme for DC products has resulted in motors and drives that are compact and modular in design. This, coupled with a high power density, has provided numerous applications with the ideal solution.
Along with its manufacturing and assembly plants around the world, ABB has sales and service facilities in over 140 countries.
